+
+Basic Installation
+==================
+
+   Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.  Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the `make install' phase executed with root
+     privileges.
+
+  5. Optionally, type `make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior `make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type `make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide `make
+     distcheck', which can by used by developers to test that all other
+     targets like `make install' and `make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.  This
+is known as a "VPATH" build.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'.  Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated.  The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the `DESTDIR' variable.  For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names.  The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of `make' will be.  For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved.  Use GNU `make'
+instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
+a workaround.  If GNU CC is not installed, it is therefore recommended
+to try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+   On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+     Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+     Print a summary of the options unique to this package's
+     `configure', and exit.  The `short' variant lists options used
+     only in the top level, while the `recursive' variant lists options
+     also present in any nested packages.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names::
+     for more details, including other options available for fine-tuning
+     the installation locations.
+
+`--no-create'
+`-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+This directory contains components use to build an autoconf-ready package
+of the SQLite amalgamation:  sqlite-autoconf-30XXXXXX.tar.gz
+
+To build the autoconf amalgamation, run from the top-level:
+
+   ./configure
+   make amalgamation-tarball
+
+The amalgamation-tarball target (also available in "main.mk") runs the
+script tool/mkautoconfamal.sh which does the work.  Refer to that script
+for details.

+This package contains:
+
+ * the SQLite library amalgamation source code file: sqlite3.c
+ * the sqlite3.h and sqlite3ext.h header files that define the C-language
+   interface to the sqlite3.c library file
+ * the shell.c file used to build the sqlite3 command-line shell program
+ * autoconf/automake installation infrastucture for building on POSIX
+   compliant systems
+ * a Makefile.msc, sqlite3.rc, and Replace.cs for building with Microsoft
+   Visual C++ on Windows
+
+WHY USE THIS PACKAGE?
+=====================
+
+The canonical make system for SQLite requires TCL as part of the build
+process.  Various TCL scripts are used to generate parts of the code and
+TCL is used to run tests.  But some people would prefer to build SQLite
+using only generic tools and without having to install TCL.  The purpose
+of this package is to provide that capability.
+
+This package contains a pre-build SQLite amalgamation file "sqlite3.c"
+(and its associated header file "sqlite3.h").  Because the amalgamation
+has been pre-built, no TCL is required.
+
+REASONS TO USE THE CANONICAL BUILD SYSTEM RATHER THAN THIS PACKAGE
+==================================================================
+
+ * the cononical build system allows you to run tests to verify that
+   the build worked
+ * the canonical build system supports more compile-time options
+ * the canonical build system works for any arbitrary check-in to
+   the SQLite source tree
+
+Step-by-step instructions on how to build using the canonical make
+system for SQLite can be found at:
+
+  https://sqlite.org/src/doc/trunk/doc/compile-for-unix.md
+  https://sqlite.org/src/doc/trunk/doc/compile-for-windows.md
+
+
+SUMMARY OF HOW TO BUILD USING THIS PACKAGE
+==========================================
+
+  Unix:      ./configure; make
+  Windows:   nmake /f Makefile.msc
+
+BUILDING ON POSIX
+=================
+
+The generic installation instructions for autoconf/automake are found
+in the INSTALL file.
+
+The following SQLite specific boolean options are supported:
+
+  --enable-readline           use readline in shell tool   [default=yes]
+  --enable-threadsafe         build a thread-safe library  [default=yes]
+  --enable-dynamic-extensions support loadable extensions  [default=yes]
+
+The default value for the CFLAGS variable (options passed to the C
+compiler) includes debugging symbols in the build, resulting in larger
+binaries than are necessary. Override it on the configure command
+line like this:
+
+  $ CFLAGS="-Os" ./configure
+
+to produce a smaller installation footprint.
+
+Other SQLite compilation parameters can also be set using CFLAGS. For
+example:
+
+  $ CFLAGS="-Os -DSQLITE_THREADSAFE=0" ./configure
+
+
+BUILDING WITH MICROSOFT VISUAL C++
+==================================
+
+To compile for Windows using Microsoft Visual C++:
+
+  $ nmake /f Makefile.msc
+
+Using Microsoft Visual C++ 2005 (or later) is recommended.  Several Windows
+platform variants may be built by adding additional macros to the NMAKE
+command line.
+
+
+Other preprocessor defines
+--------------------------
+
+Additionally, preprocessor defines may be specified by using the OPTS macro
+on the NMAKE command line.  However, not all possible preprocessor defines
+may be specified in this manner as some require the amalgamation to be built
+with them enabled (see http://www.sqlite.org/compile.html). For example, the
+following will work:
+
+  "OPTS=-DSQLITE_ENABLE_STAT4=1 -DSQLITE_OMIT_JSON=1"
+
+However, the following will not compile unless the amalgamation was built
+with it enabled:
+
+  "OPTS=-DSQLITE_ENABLE_UPDATE_DELETE_LIMIT=1"

+This is the SQLite extension for Tcl using the Tcl Extension
+Architecture (TEA). 
+
+----------------------- A BETTER WAY ---------------------------
+
+A better way to build the TCL extension for SQLite is to use the
+canonical source code tarball.  For Unix:
+
+    ./configure --with-tclsh=$(TCLSH)
+    make tclextension-install
+
+For Windows:
+
+    nmake /f Makefile.msc tclextension-install TCLSH_CMD=$(TCLSH)
+
+In both of the above, replace $(TCLSH) with the full pathname of
+of the tclsh that you want the SQLite extension to work with.  See
+step-by-step instructions at the links below for more information:
+
+    https://sqlite.org/src/doc/trunk/doc/compile-for-unix.md
+    https://sqlite.org/src/doc/trunk/doc/compile-for-windows.md
+
+The whole point of the amalgamation-autoconf tarball (in which this
+README.txt file is embedded) is to provide a means of compiling
+SQLite that does not require first installing TCL and/or "tclsh".
+The canonical Makefile in the SQLite source tree provides more
+capabilities (such as the the ability to run test cases to ensure
+that the build worked) and is better maintained.  The only
+downside of the canonical Makfile is that it requires a TCL
+installation.  But if you are wanting to build the TCL extension for
+SQLite, then presumably you already have a TCL installation.  So why
+not just use the more-capable and better-maintained canoncal Makefile?
+
+This TEA builder is derived from code found at
+
+    http://core.tcl-lang.org/tclconfig
+    http://core.tcl-lang.org/sampleextension
+
+The SQLite developers do not understand how it works.  It seems to
+work for us.  It might also work for you.  But we cannot promise that.
+
+If you want to use this TEA builder and it works for you, that's fine.
+But if you have trouble, the first thing you should do is go back
+to using the canonical Makefile in the SQLite source tree.
+
+------------------------------------------------------------------
+
+
+UNIX BUILD
+==========
+
+Building under most UNIX systems is easy, just run the configure script
+and then run make. For more information about the build process, see
+the tcl/unix/README file in the Tcl src dist. The following minimal
+example will install the extension in the /opt/tcl directory.
+
+	$ cd sqlite-*-tea
+	$ ./configure --prefix=/opt/tcl
+	$ make
+	$ make install
+
+WINDOWS BUILD
+=============
+
+The recommended method to build extensions under windows is to use the
+Msys + Mingw build process. This provides a Unix-style build while
+generating native Windows binaries. Using the Msys + Mingw build tools
+means that you can use the same configure script as per the Unix build
+to create a Makefile. See the tcl/win/README file for the URL of
+the Msys + Mingw download.
+
+If you have VC++ then you may wish to use the files in the win
+subdirectory and build the extension using just VC++. These files have
+been designed to be as generic as possible but will require some
+additional maintenance by the project developer to synchronise with
+the TEA configure.in and Makefile.in files. Instructions for using the
+VC++ makefile are written in the first part of the Makefile.vc
+file.

+#    headers
+# 7. Parse the OPTS macro value for user-specified build configuration
+# 8. Parse the STATS macro value for statistics instrumentation
+# 9. Parse the CHECKS macro for additional compilation checks
+# 10. Based on this selected configuration, construct the output
+#     directory and file paths
+# 11. Construct the paths where the package is to be installed

+Maintaining Autosetup in the SQLite Tree
+========================================================================
+
+This document provides some tips and reminders for the SQLite
+developers regarding using and maintaining the [Autosetup][]-based
+build infrastructure. It is not an [Autosetup][] reference.
+
+**Table of Contents**:
+
+- [Autosetup API Reference](#apiref)
+- [API Tips](#apitips)
+- [Ensuring TCL Compatibility](#tclcompat)
+- [Design Conventions](#conventions)
+  - Symbolic Names of Feature Flags
+  - Do Not Update Global Shared State
+- [Updating Autosetup](#updating)
+
+------------------------------------------------------------------------
+
+<a name="apiref"></a>
+Autosetup API Reference
+========================================================================
+
+The Autosetup API is quite extensive and can be read either in
+the [files in the `autosetup` dir](/dir/autosetup) or using:
+
+>
+```
+$ ./configure --reference | less
+```
+
+That will include any docs from any TCL files in the `./autosetup` dir
+which contain certain (simple) markup defined by autosetup.
+
+This project's own autosetup-related APIs are in [proj.tcl][] or
+[auto.def][].  The former contains helper APIs which are, more or
+less, portable across projects (that file is re-used as-is in other
+projects) and all have a `proj-` name prefix. The latter is the main
+configure script driver and contains related functions which are
+specific to this tree.
+
+
+<a name="apitips"></a>
+Autosetup API Tips
+========================================================================
+
+This section briefly covers only APIs which are frequently useful in
+day-to-day maintenance and might not be immediately recognized as such
+obvious from a casual perusal of [auto.def][]. The complete docs of
+those with `proj-` prefix can be found in [proj.tcl][]. The others are
+scattered around [the TCL files in ./autosetup](/dir/autosetup).
+
+In (mostly) alphabetical order:
+
+- **`file-isexec filename`**\  
+  Should be used in place of `[file executable]`, as it will also
+  check for `${filename}.exe` on Windows platforms. However, on such
+  platforms is also assumes that _any_ existing file is executable.
+
+- **`get-env VAR ?default?`**\  
+  Will fetch an "environment variable"
+  from the first of either: (1) a KEY=VALUE passed to the configure
+  script or (2) the system's environment variables. Not to be confused
+  with `getenv`, which only does the latter and is rarely, if ever,
+  useful in this tree.
+  - **`proj-get-env VAR ?default?`**\  
+    Works like `get-env` but will, if that function finds no match,
+    look for a file named `./.env-$VAR` and, if found, return its
+    trimmed contents. This can be used, e.g., to set a developer's
+    local preferences for the default `CFLAGS`.
+
+- **`define-for-opt flag defineName ?checkingMsg? ?yesVal=1? ?noVal=0?`**\  
+  `[define $defineName]` to either `$yesVal` or `$noVal`, depending on
+  whether `--$flag` is truthy or not. `$checkingMsg` is a
+  human-readable description of the check being made, e.g. "enable foo
+  bar baz?" If no `checkingMsg` is provided, the operation is silent.\  
+  Potential TODO: change the final two args to `-yes` and `-no`
+  flags. They're rarely needed, though: search [auto.def][] for
+  `TSTRNNR_OPTS` for an example of where they are used.
+
+- **`proj-fatal msg`**\  
+  Emits `$msg` to stderr and exits with non-zero.
+
+- **`proj-if-opt-truthy flag thenScript ?elseScript?`**\  
+  Evals `thenScript` if the given `--flag` is truthy, else it
+  evals the optional `elseScript`.
+
+- **`proj-indented-notice ?-error? ?-notice? msg`**\  
+  Breaks its `msg` argument into lines, trims them, and emits them
+  with consistent indentation. Exactly how it emits depends on the
+  flags passed to it (or not), as covered in its docs. This will stick
+  out starkly from normal output and is intended to be used only for
+  important notices.
+
+- **`proj-opt-truthy flag`**\  
+  Returns 1 if `--flag`'s value is "truthy," i.e. one of (1, on,
+  enabled, yes, true).
+
+- **`proj-opt-was-provided FLAG`**\  
+  Returns 1 if `--FLAG` was explicitly provided to configure,
+  else 0. This distinction can be used to determine, e.g., whether
+  `--with-readline` was provided or whether we're searching for
+  readline by default. In the former case, failure to find it should
+  be treated as fatal, where in the latter case it's not.
+
+- **`proj-val-truthy value`**\  
+  Returns 1 if `$value` is "truthy," See `proj-opt-truthy` for the definition
+  of "truthy."
+
+- **`proj-warn msg`**\  
+  Emits `$msg` to stderr. Closely-related is autosetup's `user-notice`
+  (described below).
+
+- **`sqlite-add-feature-flag ?-shell? FLAG...`**\  
+  Adds the given feature flag to the CFLAGS which are specific to building
+  the library. It's intended to be passed one or more `-DSQLITE_ENABLE_...`,
+  or similar, flags. If the `-shell` flag is used then it also passes
+  its arguments to `sqlite-add-shell-opt`. This is a no-op if `FLAG`
+  is not provided or is empty.
+
+- **`sqlite-add-shell-opt FLAG...`**\  
+  The shell-specific counterpart of `sqlite-add-feature-flag`.
+
+- **`user-notice msg`**\  
+  Queues `$msg` to be sent to stderr, but does not emit it until
+  either `show-notices` is called or the next time autosetup would
+  output something (it internally calls `show-notices`). This can be
+  used to generate warnings between a "checking for..." message and
+  its resulting "yes/no/whatever" message in such a way as to not
+  spoil the layout of such messages.

+Ensuring TCL Compatibility
+========================================================================
+
+It is important that any TCL files used by the configure process
+remain compatible with both [JimTCL][] and the canonical TCL. Though
+JimTCL has outstanding compatibility with canonical TCL, it does have
+a few corners with incompatibilities, e.g. regular expressions. If a
+script runs in JimTCL without using any JimTCL-specific features, then
+it's a certainty that it will run in canonical TCL as well. The
+opposite, however, is not _always_ the case.
+
+When [`./configure`](/file/configure) is run, it goes through a
+bootstrapping process to find a suitable TCL with which to run the
+autosetup framework. The first step involves [finding or building a
+TCL shell](/file/autosetup/autosetup-find-tclsh).  That will first
+search for an available `tclsh` (under several common names,
+e.g. `tclsh8.6`) before falling back to compiling the copy of
+`jimsh0.c` included in the source tree. i.e. it will prefer to use a
+system-installed TCL for running the configure script. Once it finds
+(or builds) a TCL shell, it then runs [a sanity test to ensure that
+the shell is suitable](/file/autosetup/autosetup-test-tclsh) before
+using it to run the main autosetup app.
+
+There are two simple ways to ensure that running of the configure
+process uses JimTCL instead of the canonical `tclsh`, and either
+approach provides equally high assurances about configure script
+compatibility across TCL implementations:
+
+1. Build on a system with no `tclsh` installed in the `$PATH`. In that
+   case, the configure process will fall back to building the in-tree
+   copy of JimTCL.
+
+2. Manually build `./jimsh0` in the top of the checkout with:\  
+   `cc -o jimsh0 autosetup/jimsh0.c`\  
+   With that in place, the configure script will prefer to use that
+   before looking for a system-level `tclsh`. Be aware, though, that
+   `make distclean` will remove that file.
+
+**Note that `jimsh0` is distinctly different** from the `jimsh` which
+gets built for code-generation purposes. The latter requires
+non-default build flags to enable features which are
+platform-dependent, most notably to make its `[file normalize]` work.
+This means, for example, that the configure script and its utility
+APIs must not use `[file normalize]`, but autosetup provides a TCL
+implementation of `[file-normalize]` (note the dash) for portable use
+in the configure script.
+
+
+<a name="conventions"></a>
+Design Conventions
+========================================================================
+
+This section describes the motivations for the most glaring of the
+build's design decisions, in particular how they deviate from
+historical, or even widely-conventional, practices.
+
+Symbolic Names of Feature Flags
+------------------------------------------------------------------------
+
+Historically, the project's makefile has exclusively used
+`UPPER_UNDERSCORE` form for makefile variables. This build, however,
+primarily uses `X.y` format, where `X` is often a category label,
+e.g. `CFLAGS` and `y` is the specific instance of that category,
+e.g. `CFLAGS.readline`.
+
+When the configure script exports flags for consumption by filtered
+files, e.g. [Makefile.in][] and the generated
+`sqlite_cfg.h`, it does so in the more conventional `X_Y` form because
+those flags get exported as as C `#define`s to `sqlite_cfg.h`, where
+dots are not permitted.
+
+The `X.y` convention is used in the makefiles primarily because the
+person who did the initial port finds that considerably easier on the
+eyes and fingers. In practice, the `X_Y` form of such exports is used
+exactly once in [Makefile.in][], where it's translated into into `X.y`
+form for consumption by [Makefile.in][] and [main.mk][]. For example:
+
+>
+```
+LDFLAGS.shobj = @SHOBJ_LDFLAGS@
+LDFLAGS.zlib = @LDFLAGS_ZLIB@
+LDFLAGS.math = @LDFLAGS_MATH@
+```
+
+(That first one is defined by autosetup, and thus applies "LDFLAGS" as
+the suffix rather than the prefix. Which is more legible is a matter
+of taste, for which there is no accounting.)
+
+
+Do Not Update Global Shared State
+------------------------------------------------------------------------
+
+In both the legacy Autotools-driven build and in common Autosetup
+usage, feature tests performed by the configure script may amend
+global flags such as `LIBS`, `LDFLAGS`, and `CFLAGS`[^as-cflags].  That's
+appropriate for a makefile which builds a single deliverable, but less
+so for makefiles which produce multiple deliverables. Drawbacks of
+that approach include:
+
+- It's unlikely that every single deliverable will require the same
+  core set of those flags.
+- It can be difficult to determine the origin of any given change to
+  that global state because those changes are hidden behind voodoo performed
+  outside the immediate visibility of the configure script's
+  maintainer.
+- It can force the maintainers of the configure script to place tests
+  in a specific order so that the resulting flags get applied at
+  the correct time and/or in the correct order.\  
+  (A real-life example: before the approach described below was taken
+  to collecting build-time flags, the test for `-rpath` had to come
+  _after_ the test for zlib because the results of the `-rpath` test
+  implicitly modified global state which broke the zlib feature
+  test. Because the feature tests no longer (intentionally) modify
+  global state, that is not an issue.)
+
+In this build, cases where feature tests modify global state in such a
+way that it may impact later feature tests are either (A) very
+intentionally defined to do so (e.g. the `--with-wasi-sdk` flag has
+invasive side-effects) or (B) are oversights (i.e. bugs).
+
+This tree's [configure script][auto.def], [utility APIs][proj.tcl],
+[Makefile.in][], and [main.mk][] therefore strive to separate the
+results of any given feature test into its own well-defined
+variables. For example:
+
+- The linker flags for zlib are exported from the configure script as
+  `LDFLAGS_ZLIB`, which [Makefile.in][] and [main.mk][] then expose as
+  `LDFLAGS.zlib`.
+- `CFLAGS_READLINE` (a.k.a. `CFLAGS.readline`) contains the `CFLAGS`
+  needed for including `libreadline`, `libedit`, or `linenoise`, and
+  `LDFLAGS_READLINE` (a.k.a. `LDFLAGS.readline`) is its link-time
+  counterpart.
+
+It is then up to the Makefile to apply and order the flags however is
+appropriate.
+
+At the end of the configure script, the global `CFLAGS` _ideally_
+holds only flags which are either relevant to all targets or, failing
+that, will have no unintended side-effects on any targets. That said:
+clients frequently pass custom `CFLAGS` to `./configure` or `make` to
+set library-level feature toggles, e.g. `-DSQLITE_OMIT_FOO`, in which
+case there is no practical way to avoid "polluting" the builds of
+arbitrary makefile targets with those. _C'est la vie._
+
+
+[^as-cflags]: But see this article for a detailed discussion of how
+    autosetup currently deals specifically with CFLAGS:
+    <https://msteveb.github.io/autosetup/articles/handling-cflags/>
+
+
+<a name="updating"></a>
+Updating Autosetup
+========================================================================
+
+Updating autosetup is, more often than not, painless. It requires having
+a checked-out copy of [the autosetup git repository][autosetup-git]:
+
+>
+```
+$ git clone https://github.com/msteveb/autosetup
+$ cd autosetup
+# Or, if it's already checked out:
+$ git pull
+```
+
+Then, from the top-most directory of an SQLite checkout:
+
+>
+```
+$ /path/to/autosetup-checkout/autosetup --install .
+$ fossil status # show the modified files
+```
+
+Unless the upgrade made any incompatible changes (which is exceedingly
+rare), that's all there is to it. Check over the diff, test the
+configure process, and check it in.

+# Configuration subroutine to validate and canonicalize a configuration type.
+# Supply the specified configuration type as an argument.
+# If it is invalid, we print an error message on stderr and exit with code 1.
+# Otherwise, we print the canonical config type on stdout and succeed.
+
+# You can get the latest version of this script from:
+# https://git.savannah.gnu.org/cgit/config.git/plain/config.sub
+
+# This file is supposed to be the same for all GNU packages
+# and recognize all the CPU types, system types and aliases
+# that are meaningful with *any* GNU software.
+# Each package is responsible for reporting which valid configurations
+# it does not support.  The user should be able to distinguish
+# a failure to support a valid configuration from a meaningless
+# configuration.
+
+# The goal of this file is to map all the various variations of a given
+# machine specification into a single specification in the form:
+#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
+# It is wrong to echo any other type of specification.
+
+# The "shellcheck disable" line above the timestamp inhibits complaints
+# about features and limitations of the classic Bourne shell that were
+# superseded or lifted in POSIX.  However, this script identifies a wide
+# variety of pre-POSIX systems that do not have POSIX shells at all, and
+# even some reasonably current systems (Solaris 10 as case-in-point) still
+# have a pre-POSIX /bin/sh.

+# Routines for Steve Bennett's autosetup which are common to trees
+# managed in and around the umbrella of the SQLite project.
+#
+# The intent is that these routines be relatively generic, independent
+# of a given project.
+#
+# This file was initially derived from one used in the libfossil
+# project, authored by the same person who ported it here, and this is
+# noted here only as an indication that there are no licensing issues

+########################################################################
+#
+# Design notes:
+#
+# - Symbols with a suffix of _ are intended for internal use within
+#   this file, and are not part of the API which auto.def files should
+#   rely on.
+#
+# - By and large, autosetup prefers to update global state with the
+#   results of feature checks, e.g. whether the compiler supports flag
+#   --X.  In this developer's opinion that (A) causes more confusion
+#   than it solves[^1] and (B) adds an unnecessary layer of "voodoo"
+#   between the autosetup user and its internals. This module, in
+#   contrast, instead injects the results of its own tests into
+#   well-defined variables and leaves the integration of those values
+#   to the caller's discretion.
+#
+# [1]: As an example: testing for the -rpath flag, using
+# cc-check-flags, can break later checks which use
+# [cc-check-function-in-lib ...] because the resulting -rpath flag
+# implicitly becomes part of those tests. In the case of an rpath
+# test, downstream tests may not like the $prefix/lib path added by
+# the rpath test. To avoid such problems, we avoid (intentionally)
+# updating global state via feature tests.

+# A toplevel window is created that allows you to type in SQL commands to

+SQLite's OS layer contains the following definitions used in F2FS related
+calls:
+
+#define F2FS_IOCTL_MAGIC        0xf5
+#define F2FS_IOC_START_ATOMIC_WRITE     _IO(F2FS_IOCTL_MAGIC, 1)
+#define F2FS_IOC_COMMIT_ATOMIC_WRITE    _IO(F2FS_IOCTL_MAGIC, 2)

+#define F2FS_FEATURE_ATOMIC_WRITE       0x0004
+
+After opening a database file on Linux (including Android), SQLite determines
+whether or not a file supports F2FS atomic commits as follows:
+
+  u32 flags = 0;
+  rc = ioctl(fd, F2FS_IOC_GET_FEATURES, &flags);
+  if( rc==0 && (flags & F2FS_FEATURE_ATOMIC_WRITE) ){
+    /* File supports F2FS atomic commits */
+  }else{
+    /* File does NOT support F2FS atomic commits */
+  }
+
+where "fd" is the file-descriptor open on the database file.
+
+Usually, when writing to a database file that supports atomic commits, SQLite
+accumulates the entire transaction in heap memory, deferring all writes to the
+db file until the transaction is committed.
+
+When it is time to commit a transaction on a file that supports atomic
+commits, SQLite does:
+
+  /* Take an F_WRLCK lock on the database file. This prevents any other
+  ** SQLite clients from reading or writing the file until the lock
+  ** is released.  */
+  rc = fcntl(fd, F_SETLK, ...);
+  if( rc!=0 ) goto failed;
+
+  rc = ioctl(fd, F2FS_IOC_START_ATOMIC_WRITE);
+  if( rc!=0 ) goto fallback_to_legacy_journal_commit;
+
+  foreach (dirty page){
+    rc = write(fd, ...dirty page...);
+    if( rc!=0 ){
+      ioctl(fd, F2FS_IOC_ABORT_VOLATILE_WRITE);
+      goto fallback_to_legacy_journal_commit;
+    }
+  }
+
+  rc = ioctl(fd, F2FS_IOC_COMMIT_ATOMIC_WRITE);
+  if( rc!=0 ){
+    ioctl(fd, F2FS_IOC_ABORT_VOLATILE_WRITE);
+    goto fallback_to_legacy_journal_commit;
+  }
+
+  /* If we get there, the transaction has been successfully 
+  ** committed to persistent storage. The following call
+  ** relinquishes the F_WRLCK lock.  */
+  fcntl(fd, F_SETLK, ...);
+
+Assumptions:
+
+1. After either of the F2FS_IOC_ABORT_VOLATILE_WRITE calls return,
+   the database file is in the state that it was in before
+   F2FS_IOC_START_ATOMIC_WRITE was invoked. Even if the ioctl()
+   fails - we're ignoring the return code.
+
+   This is true regardless of the type of error that occurred in
+   ioctl() or write().
+
+2. If the system fails before the F2FS_IOC_COMMIT_ATOMIC_WRITE is
+   completed, then following a reboot the database file is in the
+   state that it was in before F2FS_IOC_START_ATOMIC_WRITE was invoked.
+   Or, if the write was commited right before the system failed, in a 
+   state indicating that all write() calls were successfully committed
+   to persistent storage before the failure occurred.
+
+3. If the process crashes before the F2FS_IOC_COMMIT_ATOMIC_WRITE is
+   completed then the file is automatically restored to the state that
+   it was in before F2FS_IOC_START_ATOMIC_WRITE was called. This occurs
+   before the posix advisory lock is automatically dropped - there is
+   no chance that another client will be able to read the file in a
+   half-committed state before the rollback operation occurs.

+# Notes On Compiling SQLite On All Kinds Of Unix
+
+Here are step-by-step instructions on how to build SQLite from
+canonical source on any modern machine that isn't Windows.  These
+notes are tested (on 2024-10-11) on Ubuntu and on MacOS, but they
+are general and should work on most any modern unix platform.
+
+  1.  Install a C-compiler.  GCC or Clang both work fine.  If you are
+      reading this document, you've probably already done that.
+
+  2.  *(Optional):* Install TCL development libraries.  In this note,
+      we'll do a private install in the $HOME/local directory,
+      but you can make adjustments to install TCL wherever you like.
+      This document assumes you are working with TCL version 9.0.
+      <ol type="a">
+      <li>Get the TCL source archive, perhaps from
+      <https://www.tcl.tk/software/tcltk/download.html>
+      or <https://sqlite.org/tmp/tcl9.0.0.tar.gz>.
+      <li>Untar the source archive.  CD into the "unix/" subfolder
+          of the source tree.
+      <li>Run: `mkdir $HOME/local`
+      <li>Run: `./configure --prefix=$HOME/local`
+      <li>Run: `make install`
+      </ol>
+      <p>
+      As of 2024-10-25, TCL is not longer required for many
+      common build targets, such as "sqlite3.c" or the "sqlite3"
+      command-line tool.  So you can skip this step if that is all
+      you want to build.  TCL is still required to run "make test"
+      and similar, or to build the TCL extension, of course.
+
+  4.  Download the SQLite source tree and unpack it. CD into the
+      toplevel directory of the source tree.
+
+  5.  Run: `./configure --enable-all --with-tclsh=$HOME/local/bin/tclsh9.0`
+
+      You do not need to use --with-tclsh if the tclsh you want to use is the
+      first one on your PATH or if you are building without TCL.
+
+  6.  Run the "`Makefile`" makefile with an appropriate target.
+      Examples:
+      <ul>
+      <li>  `make sqlite3.c`
+      <li>  `make sqlite3`
+      <li>  `make sqldiff`
+      <li>  `make sqlite3_rsync`
+      </ul>
+      <p>None of the targets above require TCL.  TCL is only needed
+      for the following targets:
+      <ul>
+      <li>  `make tclextension-install`
+      <li>  `make devtest`
+      <li>  `make releasetest`
+      <li>  `make sqlite3_analyzer`
+      </ul>
+
+      It is not required that you run the "tclextension-install" target prior to
+      running tests.  However, the tests will run more smoothly if you do.
+      The version of SQLite used for the TCL extension does *not* need to
+      correspond to the version of SQLite under test.  So you can install the
+      SQLite TCL extension once, and then use it to test many different versions
+      of SQLite.
+
+
+  7.  For a debugging build of the CLI, where the ".treetrace" and ".wheretrace"
+      commands work, add the the --with-debug argument to configure.

+# Notes On Compiling SQLite On Windows 11
+
+Here are step-by-step instructions on how to build SQLite from
+canonical source on a new Windows 11 PC, as of 2024-10-09:
+
+  1.  Install Microsoft Visual Studio. The free "community edition" 
+      will work fine.  Do a standard install for C++ development.
+      SQLite only needs the
+      "cl" compiler and the "nmake" build tool.
+
+  2.  Under the "Start" menu, find "All Apps" then go to "Visual Studio 20XX"
+      and find "x64 Native Tools Command Prompt for VS 20XX".  Pin that
+      application to your task bar, as you will use it a lot.  Bring up
+      an instance of this command prompt and do all of the subsequent steps
+      in that "x64 Native Tools" command prompt.  (Or use "x86" if you want
+      a 32-bit build.)  The subsequent steps will not work in a vanilla
+      DOS prompt.  Nor will they work in PowerShell.
+
+  3.  *(Optional):* Install TCL development libraries.
+      This note assumes that you will
+      install the TCL development libraries in the "`c:\Tcl`" directory.
+      Make adjustments
+      if you want TCL installed somewhere else.  SQLite needs both the
+      "tclsh90.exe" command-line tool as part of the build process, and
+      the "tcl90.lib" and "tclstub.lib" libraries in order to run tests.
+      This document assumes you are working with TCL version 9.0.
+      See versions of this document from prior to 2024-10-10 for
+      instructions on how to build using TCL version 8.6.
+      <ol type="a">
+      <li>Get the TCL source archive, perhaps from
+      <https://www.tcl.tk/software/tcltk/download.html>
+      or <https://sqlite.org/tmp/tcl9.0.0.tar.gz>.
+      <li>Untar or unzip the source archive.  CD into the "win/" subfolder
+          of the source tree.
+      <li>Run: `nmake /f makefile.vc release`
+      <li>Run: `nmake /f makefile.vc INSTALLDIR=c:\Tcl install`
+      <li><i>Optional:</i> CD to `c:\Tcl\bin` and make a copy of
+          `tclsh90.exe` over into just `tclsh.exe`.
+      <li><i>Optional:</i>
+          Add `c:\Tcl\bin` to your %PATH%.  To do this, go to Settings
+          and search for "path".  Select "edit environment variables for
+          your account" and modify your default PATH accordingly.
+          You will need to close and reopen your command prompts after
+          making this change.
+      </ol>
+
+      As of 2024-10-25, TCL is not longer required for many
+      common build targets, such as "sqlite3.c" or the "sqlite3.exe"
+      command-line tool.  So you can skip this step if that is all
+      you want to build.  TCL is still required to run "make test"
+      and similar, or to build the TCL extension, of course.
+
+  4.  Download the SQLite source tree and unpack it. CD into the
+      toplevel directory of the source tree.
+
+  5.  Run the "`Makefile.msc`" makefile with an appropriate target.
+      Examples:
+      <ul>
+      <li>  `nmake /f makefile.msc`
+      <li>  `nmake /f makefile.msc sqlite3.c`
+      <li>  `nmake /f makefile.msc sqlite3.exe`
+      <li>  `nmake /f makefile.msc sqldiff.exe`
+      <li>  `nmake /f makefile.msc sqlite3_rsync.exe`
+      </ul>
+      <p>No TCL is required for the nmake targets above.  But for the ones
+      that follow, you will need a TCL installation, as described in step 3
+      above.  If you install TCL in some directory other than C:\\Tcl, then
+      you will also need to add the "TCLDIR=<i>&lt;dir&gt;</i>" option on the
+      nmake command line to tell nmake where your TCL is installed.
+      <ul>
+      <li>  `nmake /f makefile.msc tclextension-install`
+      <li>  `nmake /f makefile.msc devtest`
+      <li>  `nmake /f makefile.msc releasetest`
+      <li>  `nmake /f makefile.msc sqlite3_analyzer.exe`
+      </ul>
+
+      It is not required that you run the "tclextension-install" target prior to
+      running tests.  However, the tests will run more smoothly if you do.
+      The version of SQLite used for the TCL extension does *not* need to
+      correspond to the version of SQLite under test.  So you can install the
+      SQLite TCL extension once, and then use it to test many different versions
+      of SQLite.
+
+
+  7.  For a debugging build of the CLI, where the ".treetrace" and ".wheretrace"
+      commands work, add the DEBUG=3 argument to nmake.  Like this:
+      <ul>
+      <li> `nmake /f makefile.msc DEBUG=3 clean sqlite3.exe`
+      </ul>
+   
+
+## 32-bit Builds
+
+Doing a 32-bit build is just like doing a 64-bit build with the
+following minor changes:
+
+  1.  Use the "x86 Native Tools Command Prompt" instead of
+      "x64 Native Tools Command Prompt".  "**x86**" instead of "**x64**".
+
+  2.  Use a different installation directory for TCL.
+      The recommended directory is `c:\tcl32`.  Thus you end up
+      with two TCL builds:
+      <ul>
+      <li> `c:\tcl` &larr;  64-bit (the default)
+      <li> `c:\tcl32` &larr;  32-bit
+      </ul>
+
+  3.  Ensure that `c:\tcl32\bin` comes before `c:\tcl\bin` on
+      your PATH environment variable.  You can achieve this using
+      a command like:
+      <ul>
+      <li>  `set PATH=c:\tcl32\bin;%PATH%`
+      </ul>
+
+## Building a DLL
+
+The command the developers use for building the deliverable DLL on the 
+[download page](https://sqlite.org/download.html) is as follows:
+
+> ~~~~
+nmake /f Makefile.msc sqlite3.dll USE_NATIVE_LIBPATHS=1 "OPTS=-DSQLITE_ENABLE_FTS3=1 -DSQLITE_ENABLE_FTS4=1 -DSQLITE_ENABLE_FTS5=1 -DSQLITE_ENABLE_RTREE=1 -DSQLITE_ENABLE_JSON1=1 -DSQLITE_ENABLE_GEOPOLY=1 -DSQLITE_ENABLE_SESSION=1 -DSQLITE_ENABLE_PREUPDATE_HOOK=1 -DSQLITE_ENABLE_SERIALIZE=1 -DSQLITE_ENABLE_MATH_FUNCTIONS=1"
+~~~~
+
+That command generates both the sqlite3.dll and sqlite3.def files.  The same
+command works for both 32-bit and 64-bit builds.
+
+## Statically Linking The TCL Library
+
+Some utility programs associated with SQLite need to be linked
+with TCL in order to function.  The [sqlite3_analyzer.exe program](https://sqlite.org/sqlanalyze.html)
+is an example.  You can build as described above, and then
+enter:
+
+> ~~~~
+nmake /f Makefile.msc sqlite3_analyzer.exe
+~~~~
+
+And you will end up with a working executable.  However, that executable
+will depend on having the "tcl98.dll" library somewhere on your %PATH%.
+Use the following steps to build an executable that has the TCL library
+statically linked so that it does not depend on separate DLL:
+
+  1.  Use the appropriate "Command Prompt" window - either x86 or
+      x64, depending on whether you want a 32-bit or 64-bit executable.
+
+  2.  Untar the TCL source tarball into a fresh directory.  CD into
+      the "win/" subfolder.
+
+  3.  Run: `nmake /f makefile.vc OPTS=static shell`
+
+  4.  CD into the "Release*" subfolder that is created (note the
+      wildcard - the full name of the directory might vary).  There
+      you will find the "tcl90s.lib" file.  Copy this file into the
+      same directory that you put the "tcl90.lib" on your initial
+      installation.  (In this document, that directory is
+      "`C:\Tcl32\lib`" for 32-bit builds and
+      "`C:\Tcl\lib`" for 64-bit builds.)
+
+  5.  CD into your SQLite source code directory and build the desired
+      utility program, but add the following extra argument to the
+      nmake command line:
+      <blockquote><pre>
+      STATICALLY_LINK_TCL=1
+      </pre></blockquote>
+      <p>So, for example, to build a statically linked version of
+      sqlite3_analyzer.exe, you might type:
+      <blockquote><pre>
+      nmake /f Makefile.msc STATICALLY_LINK_TCL=1 sqlite3_analyzer.exe
+      </pre></blockquote>
+
+  6.  After your executable is built, you can verify that it does not
+      depend on the TCL DLL by running:
+      <blockquote><pre>
+      dumpbin /dependents sqlite3_analyzer.exe
+      </pre></blockquote>

+# JSON Functions Enhancements (2022)
+
+This document summaries enhancements to the SQLite JSON support added in
+early 2022.
+
+## 1.0 Change summary:
+
+  1.  New **->** and **->>** operators that work like MySQL and PostgreSQL (PG).
+  2.  JSON functions are built-in rather than being an extension.  They
+      are included by default, but can be omitted using the
+      -DSQLITE_OMIT_JSON compile-time option.
+
+
+## 2.0 New operators **->** and **->>**
+
+The SQLite language adds two new binary operators **->** and **->>**.
+Both operators are similar to json_extract().  The left operand is
+JSON and the right operand is a JSON path expression (possibly abbreviated
+for compatibility with PG - see below).  So they are similar to a
+two-argument call to json_extract().
+
+The difference between -> and ->> (and json_extract()) is as follows:
+
+  *  The -> operator always returns JSON.
+
+  *  The ->> operator converts the answer into a primitive SQL datatype
+     such as TEXT, INTEGER, REAL, or NULL.  If a JSON object or array
+     is selected, that object or array is rendered as text.  If a JSON
+     value is selected, that value is converted into its corresponding
+     SQL type
+
+  *  The json_extract() interface returns JSON when a JSON object or
+     array is selected, or a primitive SQL datatype when a JSON value
+     is selected.  This is different from MySQL, in which json_extract()
+     always returns JSON, but the difference is retained because it has
+     worked that way for 6 years and changing it now would likely break
+     a lot of legacy code.
+
+In MySQL and PG, the ->> operator always returns TEXT (or NULL) and never
+INTEGER or REAL.  This is due to limitations in the type handling capabilities
+of those systems.  In MySQL and PG, the result type a function or operator
+may only depend on the type of its arguments, never the value of its arguments.
+But the underlying JSON type depends on the value of the JSON path
+expression, not the type of the JSON path expression (which is always TEXT).
+Hence, the result type of ->> in MySQL and PG is unable to vary according
+to the type of the JSON value being extracted.
+
+The type system in SQLite is more general.  Functions in SQLite are able
+to return different datatypes depending on the value of their arguments.
+So the ->> operator in SQLite is able to return TEXT, INTEGER, REAL, or NULL
+depending on the JSON type of the value being extracted.  This means that
+the behavior of the ->> is slightly different in SQLite versus MySQL and PG
+in that it will sometimes return INTEGER and REAL values, depending on its
+inputs.  It is possible to implement the ->> operator in SQLite so that it
+always operates exactly like MySQL and PG and always returns TEXT or NULL,
+but I have been unable to think of any situations where returning the
+actual JSON value this would cause problems, so I'm including the enhanced
+functionality in SQLite.
+
+The table below attempts to summarize the differences between the
+-> and ->> operators and the json_extract() function, for SQLite, MySQL,
+and PG.  JSON values are shown using their SQL text representation but
+in a bold font.
+
+
+<table border=1 cellpadding=5 cellspacing=0>

+</table>
+
+Important points about the table above:
+
+  *  The -> operator always returns either JSON or NULL.
+
+  *  The ->> operator never returns JSON.  It always returns TEXT or NULL, or in the
+     case of SQLite, INTEGER or REAL.
+
+  *  The MySQL json_extract() function works exactly the same
+     as the MySQL -> operator.
+
+  *  The SQLite json_extract() operator works like -> for JSON objects and
+     arrays, and like ->> for JSON values.
+
+  *  The -> operator works the same for all systems.
+
+  *  The only difference in ->> between SQLite and other systems is that
+     when the JSON value is numeric, SQLite returns a numeric SQL value,
+     whereas the other systems return a text representation of the numeric
+     value.
+
+### 2.1 Abbreviated JSON path expressions for PG compatibility
+
+The table above always shows the full JSON path expression: '$.a'.  But
+PG does not accept this syntax.  PG only allows a single JSON object label
+name or a single integer array index.  In order to provide compatibility
+with PG, The -> and ->> operators in SQLite are extended to also support
+a JSON object label or an integer array index for the right-hand side
+operand, in addition to a full JSON path expression.
+
+Thus, a -> or ->> operator that works on MySQL will work in
+SQLite.  And a -> or ->> operator that works in PG will work in SQLite.
+But because SQLite supports the union of the disjoint capabilities of
+MySQL and PG, there will always be -> and ->> operators that work in
+SQLite that do not work in one of MySQL and PG.  This is an unavoidable
+consequence of the different syntax for -> and ->> in MySQL and PG.
+
+In the following table, assume that "value1" is a JSON object and
+"value2" is a JSON array.
+
+<table border=1 cellpadding=5 cellspacing=0>
+<tr><th>SQL expression     <th>Works in MySQL?<th>Works in PG?<th>Works in SQLite
+<tr><td>value1-&gt;'$.a'   <td> yes           <td>  no        <td> yes
+<tr><td>value1-&gt;'a'     <td> no            <td>  yes       <td> yes
+<tr><td>value2-&gt;'$[2]'  <td> yes           <td>  no        <td> yes
+<tr><td>value2-&gt;2       <td> no            <td>  yes       <td> yes
+</table>
+
+The abbreviated JSON path expressions only work for the -> and ->> operators
+in SQLite.  The json_extract() function, and all other built-in SQLite
+JSON functions, continue to require complete JSON path expressions for their
+PATH arguments.
+
+## 3.0 JSON moved into the core
+
+The JSON interface is now moved into the SQLite core.
+
+When originally written in 2015, the JSON functions were an extension
+that could be optionally included at compile-time, or loaded at run-time.
+The implementation was in a source file named ext/misc/json1.c in the
+source tree.  JSON functions were only compiled in if the
+-DSQLITE_ENABLE_JSON1 compile-time option was used.
+
+After these enhancements, the JSON functions are now built-ins.
+The source file that implements the JSON functions is moved to src/json.c.
+No special compile-time options are needed to load JSON into the build.
+Instead, there is a new -DSQLITE_OMIT_JSON compile-time option to leave
+them out.

+# The JSONB Format
+
+This document describes SQLite's JSONB binary encoding of
+JSON.
+
+## 1.0 What Is JSONB?
+
+Beginning with version 3.45.0 (circa 2024-01-01), SQLite supports an
+alternative binary encoding of JSON which we call "JSONB".  JSONB is
+a binary format that stored as a BLOB.
+
+The advantage of JSONB over ordinary text RFC 8259 JSON is that JSONB
+is both slightly smaller (by between 5% and 10% in most cases) and
+can be processed in less than half the number of CPU cycles.  The built-in
+[JSON SQL functions] of SQLite can accept either ordinary text JSON
+or the binary JSONB encoding for any of their JSON inputs.
+
+The "JSONB" name is inspired by [PostgreSQL](https://postgresql.org), but the
+on-disk format for SQLite's JSONB is not the same as PostgreSQL's.
+The two formats have the same name, but they have wildly different internal
+representations and are not in any way binary compatible.
+
+The central idea behind this JSONB specification is that each element
+begins with a header that includes the size and type of that element.
+The header takes the place of punctuation such as double-quotes,
+curly-brackes, square-brackets, commas, and colons.  Since the size
+and type of each element is contained in its header, the element can
+be read faster since it is no longer necessary to carefully scan forward
+looking for the closing delimiter.  The payload of JSONB is the same
+as for corresponding text JSON.  The same payload bytes occur in the
+same order.  The only real difference between JSONB and ordinary text
+JSON is that JSONB includes a binary header on
+each element and omits delimiter and separator punctuation.
+
+### 1.1 Internal Use Only
+
+The details of the JSONB are not intended to be visible to application
+developers.  Application developers should look at JSONB as an opaque BLOB
+used internally by SQLite.  Nevertheless, we want the format to be backwards
+compatible across all future versions of SQLite.  To that end, the format
+is documented by this file in the source tree.  But this file should be
+used only by SQLite core developers, not by developers of applications
+that only use SQLite.
+
+## 2.0 The Purpose Of This Document
+
+JSONB is not intended as an external format to be used by
+applications.  JSONB is designed for internal use by SQLite only.
+Programmers do not need to understand the JSONB format in order to
+use it effectively.
+Applications should access JSONB only through the [JSON SQL functions],
+not by looking at individual bytes of the BLOB.
+
+However, JSONB is intended to be portable and backwards compatible
+for all future versions of SQLite.  In other words, you should not have
+to export and reimport your SQLite database files when you upgrade to
+a newer SQLite version.  For that reason, the JSONB format needs to
+be well-defined.
+
+This document is therefore similar in purpose to the
+[SQLite database file format] document that describes the on-disk
+format of an SQLite database file.  Applications are not expected
+to directly read and write the bits and bytes of SQLite database files.
+The SQLite database file format is carefully documented so that it
+can be stable and enduring.  In the same way, the JSONB representation
+of JSON is documented here so that it too can be stable and enduring,
+not so that applications can read or writes individual bytes.
+
+## 3.0 Encoding
+
+JSONB is a direct translation of the underlying text JSON. The difference
+is that JSONB uses a binary encoding that is faster to parse compared to
+the detailed syntax of text JSON.
+
+Each JSON element is encoded as a header and a payload.  The header
+determines type of element (string, numeric, boolean, null, object, or
+array) and the size of the payload.  The header can be between 1 and
+9 bytes in size.  The payload can be any size from zero bytes up to the
+maximum allowed BLOB size.
+
+### 3.1 Payload Size
+
+The upper four bits of the first byte of the header determine size of the
+header and possibly also the size of the payload.
+If the upper four bits have a value between 0 and 11, then the header is
+exactly one byte in size and the payload size is determined by those
+upper four bits.  If the upper four bits have a value between 12 and 15,
+that means that the total header size is 2, 3, 5, or 9 bytes and the
+payload size is unsigned big-endian integer that is contained in the
+subsequent bytes.  The size integer is the one byte that following the
+initial header byte if the upper four bits
+are 12, two bytes if the upper bits are 13, four bytes if the upper bits
+are 14, and eight bytes if the upper bits are 15.  The current design
+of SQLite does not support BLOB values larger than 2GiB, so the eight-byte
+variant of the payload size integer will never be used by the current code.
+The eight-byte payload size integer is included in the specification
+to allow for future expansion.
+
+The header for an element does *not* need to be in its simplest
+form.  For example, consider the JSON numeric value "`1`".
+That element can be encode in five different ways:
+
+  *  `0x13 0x31`
+  *  `0xc3 0x01 0x31`
+  *  `0xd3 0x00 0x01 0x31`
+  *  `0xe3 0x00 0x00 0x00 0x01 0x31`
+  *  `0xf3 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01 0x31`
+
+The shortest encoding is preferred, of course, and usually happens with
+primitive elements such as numbers.  However the total size of an array
+or object might not be known exactly when the header of the element is
+first generated.  It is convenient to reserve space for the largest
+possible header and then go back and fill in the correct payload size
+at the end.  This technique can result in array or object headers that
+are larger than absolutely necessary.
+
+### 3.2 Element Type
+
+The least-significant four bits of the first byte of the header (the first
+byte masked against 0x0f) determine element type.  The following codes are
+used:
+
+<ol>
+<li type="0"><p><b>NULL</b> &rarr;
+The element is a JSON "null".  The payload size for a true JSON NULL must
+must be zero.  Future versions of SQLite might extend the JSONB format
+with elements that have a zero element type but a non-zero size.  In that
+way, legacy versions of SQLite will interpret the element as a NULL 
+for backwards compatibility while newer versions will interpret the
+element in some other way.
+
+<li value="1"><p><b>TRUE</b> &rarr;
+The element is a JSON "true".  The payload size must be zero for a actual
+"true" value.  Elements with type 1 and a non-zero payload size are
+reserved for future expansion.  Legacy implementations that see an element
+type of 1 with a non-zero payload size should continue to interpret that
+element as "true" for compatibility.
+
+<li value="2"><p><b>FALSE</b> &rarr;
+The element is a JSON "false".  The payload size must be zero for a actual
+"false" value.  Elements with type 2 and a non-zero payload size are
+reserved for future expansion.  Legacy implementations that see an element
+type of 2 with a non-zero payload size should continue to interpret that
+element as "false" for compatibility.
+
+<li value="3"><p><b>INT</b> &rarr;
+The element is a JSON integer value in the canonical
+RFC 8259 format, without extensions.  The payload is the ASCII
+text representation of that numeric value.
+
+<li value="4"><p><b>INT5</b> &rarr;
+The element is a JSON integer value that is not in the
+canonical format.   The payload is the ASCII
+text representation of that numeric value.  Because the payload is in a
+non-standard format, it will need to be translated when the JSONB is
+converted into RFC 8259 text JSON.
+
+<li value="5"><p><b>FLOAT</b> &rarr;
+The element is a JSON floating-point value in the canonical
+RFC 8259 format, without extensions.  The payload is the ASCII
+text representation of that numeric value.
+
+<li value="6"><p><b>FLOAT5</b> &rarr;
+The element is a JSON floating-point value that is not in the
+canonical format.   The payload is the ASCII
+text representation of that numeric value.  Because the payload is in a
+non-standard format, it will need to be translated when the JSONB is
+converted into RFC 8259 text JSON.
+
+<li value="7"><p><b>TEXT</b> &rarr;
+The element is a JSON string value that does not contain
+any escapes nor any characters that need to be escaped for either SQL or
+JSON.  The payload is the UTF8 text representation of the string value.
+The payload does <i>not</i> include string delimiters.
+
+<li value="8"><p><b>TEXTJ</b> &rarr;
+The element is a JSON string value that contains
+RFC 8259 character escapes (such as "<tt>\n</tt>" or "<tt>\u0020</tt>").
+Those escapes will need to be translated into actual UTF8 if this element
+is [json_extract|extracted] into SQL.
+The payload is the UTF8 text representation of the escaped string value.
+The payload does <i>not</i> include string delimiters.
+
+<li value="9"><p><b>TEXT5</b> &rarr;
+The element is a JSON string value that contains
+character escapes, including some character escapes that part of JSON5
+and which are not found in the canonical RFC 8259 spec.
+Those escapes will need to be translated into standard JSON prior to
+rendering the JSON as text, or into their actual UTF8 characters if this
+element is [json_extract|extracted] into SQL.
+The payload is the UTF8 text representation of the escaped string value.
+The payload does <i>not</i> include string delimiters.
+
+<li value="10"><p><b>TEXTRAW</b> &rarr;
+The element is a JSON string value that contains
+UTF8 characters that need to be escaped if this string is rendered into
+standard JSON text.
+The payload does <i>not</i> include string delimiters.
+
+<li value="11"><p><b>ARRAY</b> &rarr;
+The element is a JSON array.  The payload contains
+JSONB elements that comprise values contained within the array.
+
+<li value="12"><p><b>OBJECT</b> &rarr;
+The element is a JSON object.  The payload contains
+pairs of JSONB elements that comprise entries for the JSON object.
+The first element in each pair must be a string (types 7 through 10).
+The second element of each pair may be any types, including nested
+arrays or objects.
+
+<li value="13"><p><b>RESERVED-13</b> &rarr;
+Reserved for future expansion.  Legacy implements that encounter this
+element type should raise an error.
+
+<li value="14"><p><b>RESERVED-14</b> &rarr;
+Reserved for future expansion.  Legacy implements that encounter this
+element type should raise an error.
+
+<li value="15"><p><b>RESERVED-15</b> &rarr;
+Reserved for future expansion.  Legacy implements that encounter this
+element type should raise an error.
+</ol>
+
+Element types outside the range of 0 to 12 are reserved for future
+expansion.  The current implement raises an error if see an element type
+other than those listed above.  However, future versions of SQLite might
+use of the three remaining element types to implement indexing or similar
+optimizations, to speed up lookup against large JSON arrays and/or objects.
+
+### 3.3 Design Rationale For Element Types
+
+A key goal of JSONB is that it should be quick to translate
+to and from text JSON and/or be constructed from SQL values.
+When converting from text into JSONB, we do not want the
+converter subroutine to burn CPU cycles converting elements
+values into some standard format which might never be used.
+Format conversion is "lazy" - it is deferred until actually
+needed.  This has implications for the JSONB format design:
+
+  1.   Numeric values are stored as text, not a numbers.  The values are
+       a direct copy of the text JSON values from which they are derived.
+
+  2.   There are multiple element types depending on the details of value
+       formats.  For example, INT is used for pure RFC-8259 integer
+       literals and INT5 exists for JSON5 extensions such as hexadecimal
+       notation.  FLOAT is used for pure RFC-8259 floating point literals
+       and FLOAT5 is used for JSON5 extensions.  There are four different
+       representations of strings, depending on where the string came from
+       and how special characters within the string are escaped.
+
+A second goal of JSONB is that it should be capable of serving as the
+"parse tree" for JSON when a JSON value is being processed by the
+various [JSON SQL functions] built into SQLite.  Before JSONB was
+developed, operations such [json_replace()] and [json_patch()]
+and similar worked in three stages:
+
+
+  1.  Translate the text JSON into a internal format that is
+      easier to scan and edit.
+  2.  Perform the requested operation on the JSON.
+  3.  Translate the internal format back into text.
+
+JSONB seeks to serve as the internal format directly - bypassing
+the first and third stages of that process.  Since most of the CPU
+cycles are spent on the first and third stages, that suggests that
+JSONB processing will be much faster than text JSON processing.
+
+So when processing JSONB, only the second stage of the three-stage
+process is required.  But when processing text JSON, it is still necessary
+to do stages one and three.  If JSONB is to be used as the internal
+binary representation, this is yet another reason to store numeric
+values as text.  Storing numbers as text minimizes the amount of
+conversion work needed for stages one and three.  This is also why
+there are four different representations of text in JSONB.  Different
+text representations are used for text coming from different sources
+(RFC-8259 JSON, JSON5, or SQL string values) and conversions only
+happen if and when they are actually needed.
+
+### 3.4 Valid JSONB BLOBs
+
+A valid JSONB BLOB consists of a single JSON element.  The element must
+exactly fill the BLOB.  This one element is often a JSON object or array
+and those usually contain additional elements as its payload, but the
+element can be a primite value such a string, number, boolean, or null.
+
+When the built-in JSON functions are attempting to determine if a BLOB
+argument is a JSONB or just a random BLOB, they look at the header of
+the outer element to see that it is well-formed and that the element
+completely fills the BLOB.  If these conditions are met, then the BLOB
+is accepted as a JSONB value.

+<h1 align='center'>The Lemon Parser Generator</h1>
+
+<p>Lemon is an LALR(1) parser generator for C.
+It does the same job as "bison" and "yacc".
+But Lemon is not a bison or yacc clone.  Lemon
+uses a different grammar syntax which is designed to
+reduce the number of coding errors.  Lemon also uses a
+parsing engine that is faster than yacc and
+bison and which is both reentrant and threadsafe.
+(Update: Since the previous sentence was written, bison
+has also been updated so that it too can generate a
+reentrant and threadsafe parser.)
+Lemon also implements features that can be used
+to eliminate resource leaks, making it suitable for use
+in long-running programs such as graphical user interfaces
+or embedded controllers.</p>

+<h2>2.0 Security Note</h2>
+
+<p>The language parser code created by Lemon is very robust and
+is well-suited for use in internet-facing applications that need to
+safely process maliciously crafted inputs.</p>
+
+<p>The "lemon.exe" command-line tool itself works great when given a valid
+input grammar file and almost always gives helpful
+error messages for malformed inputs.  However,  it is possible for
+a malicious user to craft a grammar file that will cause 
+lemon.exe to crash.
+We do not see this as a problem, as lemon.exe is not intended to be used
+with hostile inputs.
+To summarize:</p>
+
+<ul>
+<li>Parser code generated by lemon &rarr; Robust and secure
+<li>The "lemon.exe" command line tool itself &rarr; Not so much
+</ul>
+
+<a id="optheory"></a>
+<h2>3.0 Theory of Operation</h2>
+
+<p>Lemon is computer program that translates a context free grammar (CFG)
+for a particular language into C code that implements a parser for
+that language.
+The Lemon program has two inputs:</p>
+<ul>
+<li>The grammar specification.
+<li>A parser template file.
+</ul>
+<p>Typically, only the grammar specification is supplied by the programmer.
+Lemon comes with a default parser template
+("<a href="https://sqlite.org/src/file/tool/lempar.c">lempar.c</a>")
+that works fine for most applications.  But the user is free to substitute
+a different parser template if desired.</p>
+
+<p>Depending on command-line options, Lemon will generate up to
+three output files.</p>
+<ul>
+<li>C code to implement a parser for the input grammar.
+<li>A header file defining an integer ID for each terminal symbol
+    (or "token").
+<li>An information file that describes the states of the generated parser
+    automaton.
+</ul>
+<p>By default, all three of these output files are generated.
+The header file is suppressed if the "-m" command-line option is
+used and the report file is omitted when "-q" is selected.</p>
+
+<p>The grammar specification file uses a ".y" suffix, by convention.
+In the examples used in this document, we'll assume the name of the
+grammar file is "gram.y".  A typical use of Lemon would be the
+following command:</p>
+<pre>
+   lemon gram.y
+</pre>
+<p>This command will generate three output files named "gram.c",
+"gram.h" and "gram.out".
+The first is C code to implement the parser.  The second
+is the header file that defines numerical values for all
+terminal symbols, and the last is the report that explains
+the states used by the parser automaton.</p>
+
+<a id="options"></a>
+<h3>3.1 Command Line Options</h3>
+
+<p>The behavior of Lemon can be modified using command-line options.
+You can obtain a list of the available command-line options together

+<h3>3.2 The Parser Interface</h3>
+
+<p>Lemon doesn't generate a complete, working program.  It only generates
+a few subroutines that implement a parser.  This section describes
+the interface to those subroutines.  It is up to the programmer to
+call these subroutines in an appropriate way in order to produce a
+complete system.</p>
+
+<p>Before a program begins using a Lemon-generated parser, the program
+must first create the parser.
+A new parser is created as follows:</p>
+<pre>
+   void *pParser = ParseAlloc( malloc );
+</pre>
+<p>The ParseAlloc() routine allocates and initializes a new parser and
+returns a pointer to it.
+The actual data structure used to represent a parser is opaque &mdash;
+its internal structure is not visible or usable by the calling routine.
+For this reason, the ParseAlloc() routine returns a pointer to void
+rather than a pointer to some particular structure.
+The sole argument to the ParseAlloc() routine is a pointer to the
+subroutine used to allocate memory.  Typically this means malloc().</p>
+
+<p>After a program is finished using a parser, it can reclaim all
+memory allocated by that parser by calling</p>
+<pre>
+   ParseFree(pParser, free);
+</pre>
+<p>The first argument is the same pointer returned by ParseAlloc().  The
+second argument is a pointer to the function used to release bulk
+memory back to the system.</p>
+
+<p>After a parser has been allocated using ParseAlloc(), the programmer
+must supply the parser with a sequence of tokens (terminal symbols) to
+be parsed.  This is accomplished by calling the following function
+once for each token:<p>
+<pre>
+   Parse(pParser, hTokenID, sTokenData, pArg);
+</pre>
+<p>The first argument to the Parse() routine is the pointer returned by
+ParseAlloc().
+The second argument is a small positive integer that tells the parser the
+type of the next token in the data stream.
+There is one token type for each terminal symbol in the grammar.
+The gram.h file generated by Lemon contains #define statements that
+map symbolic terminal symbol names into appropriate integer values.
+A value of 0 for the second argument is a special flag to the
+parser to indicate that the end of input has been reached.
+The third argument is the value of the given token.  By default,
+the type of the third argument is "void*", but the grammar will
+usually redefine this type to be some kind of structure.
+Typically the second argument will be a broad category of tokens
+such as "identifier" or "number" and the third argument will
+be the name of the identifier or the value of the number.</p>
+
+<p>The Parse() function may have either three or four arguments,
+depending on the grammar.  If the grammar specification file requests
+it (via the <tt><a href='#extraarg'>%extra_argument</a></tt> directive),
+the Parse() function will have a fourth parameter that can be
+of any type chosen by the programmer.  The parser doesn't do anything
+with this argument except to pass it through to action routines.
+This is a convenient mechanism for passing state information down
+to the action routines without having to use global variables.</p>
+
+<p>A typical use of a Lemon parser might look something like the
+following:</p>
+<pre>
+    1 ParseTree *ParseFile(const char *zFilename){
+    2    Tokenizer *pTokenizer;
+    3    void *pParser;
+    4    Token sToken;
+    5    int hTokenId;
+    6    ParserState sState;
+    7
+    8    pTokenizer = TokenizerCreate(zFilename);
+    9    pParser = ParseAlloc( malloc );
+   10    InitParserState(&amp;sState);
+   11    while( GetNextToken(pTokenizer, &amp;hTokenId, &amp;sToken) ){
+   12       Parse(pParser, hTokenId, sToken, &amp;sState);
+   13    }
+   14    Parse(pParser, 0, sToken, &amp;sState);
+   15    ParseFree(pParser, free );
+   16    TokenizerFree(pTokenizer);
+   17    return sState.treeRoot;
+   18 }
+</pre>
+<p>This example shows a user-written routine that parses a file of
+text and returns a pointer to the parse tree.
+(All error-handling code is omitted from this example to keep it
+simple.)
+We assume the existence of some kind of tokenizer which is created
+using TokenizerCreate() on line 8 and deleted by TokenizerFree()
+on line 16.  The GetNextToken() function on line 11 retrieves the
+next token from the input file and puts its type in the
+integer variable hTokenId.  The sToken variable is assumed to be
+some kind of structure that contains details about each token,
+such as its complete text, what line it occurs on, etc.</p>
+
+<p>This example also assumes the existence of a structure of type
+ParserState that holds state information about a particular parse.
+An instance of such a structure is created on line 6 and initialized
+on line 10.  A pointer to this structure is passed into the Parse()
+routine as the optional 4th argument.
+The action routine specified by the grammar for the parser can use
+the ParserState structure to hold whatever information is useful and
+appropriate.  In the example, we note that the treeRoot field of
+the ParserState structure is left pointing to the root of the parse
+tree.</p>
+
+<p>The core of this example as it relates to Lemon is as follows:</p>
+<pre>
+   ParseFile(){
+      pParser = ParseAlloc( malloc );
+      while( GetNextToken(pTokenizer,&amp;hTokenId, &amp;sToken) ){
+         Parse(pParser, hTokenId, sToken);
+      }
+      Parse(pParser, 0, sToken);
+      ParseFree(pParser, free );
+   }
+</pre>
+<p>Basically, what a program has to do to use a Lemon-generated parser
+is first create the parser, then send it lots of tokens obtained by
+tokenizing an input source.  When the end of input is reached, the
+Parse() routine should be called one last time with a token type
+of 0.  This step is necessary to inform the parser that the end of
+input has been reached.  Finally, we reclaim memory used by the
+parser by calling ParseFree().</p>
+
+<p>There is one other interface routine that should be mentioned
+before we move on.
+The ParseTrace() function can be used to generate debugging output
+from the parser.  A prototype for this routine is as follows:</p>
+<pre>
+   ParseTrace(FILE *stream, char *zPrefix);
+</pre>
+<p>After this routine is called, a short (one-line) message is written
+to the designated output stream every time the parser changes states
+or calls an action routine.  Each such message is prefaced using
+the text given by zPrefix.  This debugging output can be turned off
+by calling ParseTrace() again with a first argument of NULL (0).</p>
+
+<a id="onstack"></a>
+<h4>3.2.1 Allocating The Parse Object On Stack</h4>
+
+<p>If all calls to the Parse() interface are made from within
+<a href="#pcode"><tt>%code</tt> directives</a>, then the parse
+object can be allocated from the stack rather than from the heap.
+These are the steps:
+
+<ul>
+<li> Declare a local variable of type "yyParser"
+<li> Initialize the variable using ParseInit()
+<li> Pass a pointer to the variable in calls to Parse()
+<li> Deallocate substructure in the parse variable using ParseFinalize().
+</ul>
+
+<p>The following code illustrates how this is done:
+
+<pre>
+   ParseFile(){
+      yyParser x;
+      ParseInit( &x );
+      while( GetNextToken(pTokenizer,&amp;hTokenId, &amp;sToken) ){
+         Parse(&x, hTokenId, sToken);
+      }
+      Parse(&x, 0, sToken);
+      ParseFinalize( &x );
+   }
+</pre>
+
+<a id="ifsum"></a>
+<h4>3.2.2 Interface Summary</h4>
+
+<p>Here is a quick overview of the C-language interface to a
+Lemon-generated parser:</p>
+
+<blockquote><pre>
+void *ParseAlloc( (void*(*malloc)(size_t) );
+void ParseFree(void *pParser, (void(*free)(void*) );
+void Parse(void *pParser, int tokenCode, ParseTOKENTYPE token, ...);
+void ParseTrace(FILE *stream, char *zPrefix);
+</pre></blockquote>
+
+<p>Notes:</p>
+<ul>
+<li> Use the <a href="#pname"><tt>%name</tt> directive</a> to change
+the "Parse" prefix names of the procedures in the interface.
+<li> Use the <a href="#token_type"><tt>%token_type</tt> directive</a>
+to define the "ParseTOKENTYPE" type.
+<li> Use the <a href="#extraarg"><tt>%extra_argument</tt> directive</a>
+to specify the type and name of the 4th parameter to the
+Parse() function.
+</ul>
+
+<a id="yaccdiff"></a>
+<h3>3.3 Differences With YACC and BISON</h3>
+
+<p>Programmers who have previously used the yacc or bison parser
+generator will notice several important differences between yacc and/or
+bison and Lemon.</p>
+<ul>
+<li>In yacc and bison, the parser calls the tokenizer.  In Lemon,
+    the tokenizer calls the parser.
+<li>Lemon uses no global variables.  Yacc and bison use global variables
+    to pass information between the tokenizer and parser.
+<li>Lemon allows multiple parsers to be running simultaneously.  Yacc
+    and bison do not.
+</ul>
+<p>These differences may cause some initial confusion for programmers
+with prior yacc and bison experience.
+But after years of experience using Lemon, I firmly
+believe that the Lemon way of doing things is better.</p>
+
+<p><i>Updated as of 2016-02-16:</i>
+The text above was written in the 1990s.
+We are told that Bison has lately been enhanced to support the
+tokenizer-calls-parser paradigm used by Lemon, eliminating the
+need for global variables.</p>
+
+<a id="build"><a>
+<h3>3.4 Building The "lemon" or "lemon.exe" Executable</h3>
+
+<p>The "lemon" or "lemon.exe" program is built from a single file
+of C-code named 
+"<a href="https://sqlite.org/src/tool/lemon.c">lemon.c</a>". 
+The Lemon source code is generic C89 code that uses
+no unusual or non-standard libraries.  Any
+reasonable C compiler should suffice to compile the lemon program.  
+A command-line like the following will usually work:</p>
+
+<blockquote><pre>
+cc -o lemon lemon.c
+</pre></blockquote
+
+<p>On Windows machines with Visual C++ installed, bring up a
+"VS20<i>NN</i> x64 Native Tools Command Prompt" window and enter:
+
+<blockquote><pre>
+cl lemon.c
+</pre></blockquote>
+
+<p>Compiling Lemon really is that simple. 
+Additional compiler options such as
+"-O2" or "-g" or "-Wall" can be added if desired, but they are not
+necessary.</p>
+
+
+<a id="syntax"></a>
+<h2>4.0 Input File Syntax</h2>
+
+<p>The main purpose of the grammar specification file for Lemon is
+to define the grammar for the parser.  But the input file also
+specifies additional information Lemon requires to do its job.
+Most of the work in using Lemon is in writing an appropriate
+grammar file.</p>
+
+<p>The grammar file for Lemon is, for the most part, a free format.
+It does not have sections or divisions like yacc or bison.  Any
+declaration can occur at any point in the file.  Lemon ignores
+whitespace (except where it is needed to separate tokens), and it
+honors the same commenting conventions as C and C++.</p>
+
+<a id="tnt"></a>
+<h3>4.1 Terminals and Nonterminals</h3>
+
+<p>A terminal symbol (token) is any string of alphanumeric
+and/or underscore characters
+that begins with an uppercase letter.
+A terminal can contain lowercase letters after the first character,
+but the usual convention is to make terminals all uppercase.
+A nonterminal, on the other hand, is any string of alphanumeric
+and underscore characters than begins with a lowercase letter.
+Again, the usual convention is to make nonterminals use all lowercase
+letters.</p>
+
+<p>In Lemon, terminal and nonterminal symbols do not need to
+be declared or identified in a separate section of the grammar file.
+Lemon is able to generate a list of all terminals and nonterminals
+by examining the grammar rules, and it can always distinguish a
+terminal from a nonterminal by checking the case of the first
+character of the name.</p>
+
+<p>Yacc and bison allow terminal symbols to have either alphanumeric
+names or to be individual characters included in single quotes, like
+this: ')' or '$'.  Lemon does not allow this alternative form for
+terminal symbols.  With Lemon, all symbols, terminals and nonterminals,
+must have alphanumeric names.</p>
+
+<a id="rules"></a>
+<h3>4.2 Grammar Rules</h3>
+
+<p>The main component of a Lemon grammar file is a sequence of grammar
+rules.
+Each grammar rule consists of a nonterminal symbol followed by
+the special symbol "::=" and then a list of terminals and/or nonterminals.
+The rule is terminated by a period.
+The list of terminals and nonterminals on the right-hand side of the
+rule can be empty.
+Rules can occur in any order, except that the left-hand side of the
+first rule is assumed to be the start symbol for the grammar (unless
+specified otherwise using the <tt><a href='#start_symbol'>%start_symbol</a></tt>
+directive described below.)
+A typical sequence of grammar rules might look something like this:</p>
+<pre>
+  expr ::= expr PLUS expr.
+  expr ::= expr TIMES expr.
+  expr ::= LPAREN expr RPAREN.
+  expr ::= VALUE.
+</pre>
+
+<p>There is one non-terminal in this example, "expr", and five
+terminal symbols or tokens: "PLUS", "TIMES", "LPAREN",
+"RPAREN" and "VALUE".</p>
+
+<p>Like yacc and bison, Lemon allows the grammar to specify a block
+of C code that will be executed whenever a grammar rule is reduced
+by the parser.
+In Lemon, this action is specified by putting the C code (contained
+within curly braces <tt>{...}</tt>) immediately after the
+period that closes the rule.
+For example:</p>
+<pre>
+  expr ::= expr PLUS expr.   { printf("Doing an addition...\n"); }
+</pre>
+
+<p>In order to be useful, grammar actions must normally be linked to
+their associated grammar rules.
+In yacc and bison, this is accomplished by embedding a "$$" in the
+action to stand for the value of the left-hand side of the rule and
+symbols "$1", "$2", and so forth to stand for the value of
+the terminal or nonterminal at position 1, 2 and so forth on the
+right-hand side of the rule.
+This idea is very powerful, but it is also very error-prone.  The
+single most common source of errors in a yacc or bison grammar is
+to miscount the number of symbols on the right-hand side of a grammar
+rule and say "$7" when you really mean "$8".</p>
+
+<p>Lemon avoids the need to count grammar symbols by assigning symbolic
+names to each symbol in a grammar rule and then using those symbolic
+names in the action.
+In yacc or bison, one would write this:</p>
+<pre>
+  expr -&gt; expr PLUS expr  { $$ = $1 + $3; };
+</pre>
+<p>But in Lemon, the same rule becomes the following:</p>
+<pre>
+  expr(A) ::= expr(B) PLUS expr(C).  { A = B+C; }
+</pre>
+<p>In the Lemon rule, any symbol in parentheses after a grammar rule
+symbol becomes a place holder for that symbol in the grammar rule.
+This place holder can then be used in the associated C action to
+stand for the value of that symbol.</p>
+
+<p>The Lemon notation for linking a grammar rule with its reduce
+action is superior to yacc/bison on several counts.
+First, as mentioned above, the Lemon method avoids the need to
+count grammar symbols.
+Secondly, if a terminal or nonterminal in a Lemon grammar rule
+includes a linking symbol in parentheses but that linking symbol
+is not actually used in the reduce action, then an error message
+is generated.
+For example, the rule</p>
+<pre>
+  expr(A) ::= expr(B) PLUS expr(C).  { A = B; }
+</pre>
+<p>will generate an error because the linking symbol "C" is used
+in the grammar rule but not in the reduce action.</p>
+
+<p>The Lemon notation for linking grammar rules to reduce actions
+also facilitates the use of destructors for reclaiming memory
+allocated by the values of terminals and nonterminals on the
+right-hand side of a rule.</p>
+
+<a id='precrules'></a>
+<h3>4.3 Precedence Rules</h3>
+
+<p>Lemon resolves parsing ambiguities in exactly the same way as
+yacc and bison.  A shift-reduce conflict is resolved in favor
+of the shift, and a reduce-reduce conflict is resolved by reducing
+whichever rule comes first in the grammar file.</p>
+
+<p>Just like in
+yacc and bison, Lemon allows a measure of control
+over the resolution of parsing conflicts using precedence rules.
+A precedence value can be assigned to any terminal symbol
+using the
+<tt><a href='#pleft'>%left</a></tt>,
+<tt><a href='#pright'>%right</a></tt> or
+<tt><a href='#pnonassoc'>%nonassoc</a></tt> directives.  Terminal symbols
+mentioned in earlier directives have a lower precedence than
+terminal symbols mentioned in later directives.  For example:</p>
+
+<pre>
+   %left AND.
+   %left OR.
+   %nonassoc EQ NE GT GE LT LE.
+   %left PLUS MINUS.
+   %left TIMES DIVIDE MOD.
+   %right EXP NOT.
+</pre>
+
+<p>In the preceding sequence of directives, the AND operator is
+defined to have the lowest precedence.  The OR operator is one
+precedence level higher.  And so forth.  Hence, the grammar would
+attempt to group the ambiguous expression</p>
+<pre>
+     a AND b OR c
+</pre>
+<p>like this</p>
+<pre>
+     a AND (b OR c).
+</pre>
+<p>The associativity (left, right or nonassoc) is used to determine
+the grouping when the precedence is the same.  AND is left-associative
+in our example, so</p>
+<pre>
+     a AND b AND c
+</pre>
+<p>is parsed like this</p>
+<pre>
+     (a AND b) AND c.
+</pre>
+<p>The EXP operator is right-associative, though, so</p>
+<pre>
+     a EXP b EXP c
+</pre>
+<p>is parsed like this</p>
+<pre>
+     a EXP (b EXP c).
+</pre>
+<p>The nonassoc precedence is used for non-associative operators.
+So</p>
+<pre>
+     a EQ b EQ c
+</pre>
+<p>is an error.</p>
+
+<p>The precedence of non-terminals is transferred to rules as follows:
+The precedence of a grammar rule is equal to the precedence of the
+left-most terminal symbol in the rule for which a precedence is
+defined.  This is normally what you want, but in those cases where
+you want the precedence of a grammar rule to be something different,
+you can specify an alternative precedence symbol by putting the
+symbol in square braces after the period at the end of the rule and
+before any C-code.  For example:</p>
+
+<pre>
+   expr = MINUS expr.  [NOT]
+</pre>
+
+<p>This rule has a precedence equal to that of the NOT symbol, not the
+MINUS symbol as would have been the case by default.</p>
+
+<p>With the knowledge of how precedence is assigned to terminal
+symbols and individual
+grammar rules, we can now explain precisely how parsing conflicts
+are resolved in Lemon.  Shift-reduce conflicts are resolved
+as follows:</p>
+<ul>
+<li> If either the token to be shifted or the rule to be reduced
+     lacks precedence information, then resolve in favor of the
+     shift, but report a parsing conflict.
+<li> If the precedence of the token to be shifted is greater than
+     the precedence of the rule to reduce, then resolve in favor
+     of the shift.  No parsing conflict is reported.
+<li> If the precedence of the token to be shifted is less than the
+     precedence of the rule to reduce, then resolve in favor of the
+     reduce action.  No parsing conflict is reported.
+<li> If the precedences are the same and the shift token is
+     right-associative, then resolve in favor of the shift.
+     No parsing conflict is reported.
+<li> If the precedences are the same and the shift token is
+     left-associative, then resolve in favor of the reduce.
+     No parsing conflict is reported.
+<li> Otherwise, resolve the conflict by doing the shift, and
+     report a parsing conflict.
+</ul>
+<p>Reduce-reduce conflicts are resolved this way:</p>
+<ul>
+<li> If either reduce rule
+     lacks precedence information, then resolve in favor of the
+     rule that appears first in the grammar, and report a parsing
+     conflict.
+<li> If both rules have precedence and the precedence is different,
+     then resolve the dispute in favor of the rule with the highest
+     precedence, and do not report a conflict.
+<li> Otherwise, resolve the conflict by reducing by the rule that
+     appears first in the grammar, and report a parsing conflict.
+</ul>
+
+<a id="special"></a>
+<h3>4.4 Special Directives</h3>
+
+<p>The input grammar to Lemon consists of grammar rules and special
+directives.  We've described all the grammar rules, so now we'll
+talk about the special directives.</p>
+
+<p>Directives in Lemon can occur in any order.  You can put them before
+the grammar rules, or after the grammar rules, or in the midst of the
+grammar rules.  It doesn't matter.  The relative order of
+directives used to assign precedence to terminals is important, but
+other than that, the order of directives in Lemon is arbitrary.</p>
+
+<p>Lemon supports the following special directives:</p>
+<ul>
+<li><tt><a href='#pcode'>%code</a></tt>
+<li><tt><a href='#default_destructor'>%default_destructor</a></tt>
+<li><tt><a href='#default_type'>%default_type</a></tt>

+<li><tt><a href='#ptype'>%type</a></tt>

+</ul>
+<p>Each of these directives will be described separately in the
+following sections:</p>
+
+<a id='pcode'></a>
+<h4>4.4.1 The <tt>%code</tt> directive</h4>
+
+<p>The <tt>%code</tt> directive is used to specify additional C code that
+is added to the end of the main output file.  This is similar to
+the <tt><a href='#pinclude'>%include</a></tt> directive except that
+<tt>%include</tt> is inserted at the beginning of the main output file.</p>
+
+<p><tt>%code</tt> is typically used to include some action routines or perhaps
+a tokenizer or even the "main()" function
+as part of the output file.</p>
+
+<p>There can be multiple <tt>%code</tt> directives.  The arguments of
+all <tt>%code</tt> directives are concatenated.</p>

+<h4>4.4.2 The <tt>%default_destructor</tt> directive</h4>
+
+<p>The <tt>%default_destructor</tt> directive specifies a destructor to
+use for non-terminals that do not have their own destructor
+specified by a separate <tt>%destructor</tt> directive.  See the documentation
+on the <tt><a href='#destructor'>%destructor</a></tt> directive below for
+additional information.</p>
+
+<p>In some grammars, many different non-terminal symbols have the
+same data type and hence the same destructor.  This directive is
+a convenient way to specify the same destructor for all those
+non-terminals using a single statement.</p>
+
+<a id='default_type'></a>
+<h4>4.4.3 The <tt>%default_type</tt> directive</h4>
+
+<p>The <tt>%default_type</tt> directive specifies the data type of non-terminal
+symbols that do not have their own data type defined using a separate
+<tt><a href='#ptype'>%type</a></tt> directive.</p>
+
+<a id='destructor'></a>
+<h4>4.4.4 The <tt>%destructor</tt> directive</h4>
+
+<p>The <tt>%destructor</tt> directive is used to specify a destructor for
+a non-terminal symbol.
+(See also the <tt><a href='#token_destructor'>%token_destructor</a></tt>
+directive which is used to specify a destructor for terminal symbols.)</p>
+
+<p>A non-terminal's destructor is called to dispose of the
+non-terminal's value whenever the non-terminal is popped from
+the stack.  This includes all of the following circumstances:</p>
+<ul>
+<li> When a rule reduces and the value of a non-terminal on
+     the right-hand side is not linked to C code.
+<li> When the stack is popped during error processing.
+<li> When the ParseFree() function runs.
+</ul>
+<p>The destructor can do whatever it wants with the value of
+the non-terminal, but its design is to deallocate memory
+or other resources held by that non-terminal.</p>
+
+<p>Consider an example:</p>
+<pre>
+   %type nt {void*}
+   %destructor nt { free($$); }
+   nt(A) ::= ID NUM.   { A = malloc( 100 ); }
+</pre>
+<p>This example is a bit contrived, but it serves to illustrate how
+destructors work.  The example shows a non-terminal named
+"nt" that holds values of type "void*".  When the rule for
+an "nt" reduces, it sets the value of the non-terminal to
+space obtained from malloc().  Later, when the nt non-terminal
+is popped from the stack, the destructor will fire and call
+free() on this malloced space, thus avoiding a memory leak.
+(Note that the symbol "$$" in the destructor code is replaced
+by the value of the non-terminal.)</p>
+
+<p>It is important to note that the value of a non-terminal is passed
+to the destructor whenever the non-terminal is removed from the
+stack, unless the non-terminal is used in a C-code action.  If
+the non-terminal is used by C-code, then it is assumed that the
+C-code will take care of destroying it.
+More commonly, the value is used to build some
+larger structure, and we don't want to destroy it, which is why
+the destructor is not called in this circumstance.</p>
+
+<p>Destructors help avoid memory leaks by automatically freeing
+allocated objects when they go out of scope.
+To do the same using yacc or bison is much more difficult.</p>
+
+<a id='extraarg'></a>
+<h4>4.4.5 The <tt>%extra_argument</tt> directive</h4>
+
+<p>The <tt>%extra_argument</tt> directive instructs Lemon to add a 4th parameter
+to the parameter list of the Parse() function it generates.  Lemon
+doesn't do anything itself with this extra argument, but it does
+make the argument available to C-code action routines, destructors,
+and so forth.  For example, if the grammar file contains:</p>
+
+<pre>
+    %extra_argument { MyStruct *pAbc }
+</pre>
+
+<p>Then the Parse() function generated will have an 4th parameter
+of type "MyStruct*" and all action routines will have access to
+a variable named "pAbc" that is the value of the 4th parameter
+in the most recent call to Parse().</p>
+
+<p>The <tt>%extra_context</tt> directive works the same except that it
+is passed in on the ParseAlloc() or ParseInit() routines instead of
+on Parse().</p>
+
+<a id='extractx'></a>
+<h4>4.4.6 The <tt>%extra_context</tt> directive</h4>
+
+<p>The <tt>%extra_context</tt> directive instructs Lemon to add a 2nd parameter
+to the parameter list of the ParseAlloc() and ParseInit() functions.  Lemon
+doesn't do anything itself with these extra argument, but it does
+store the value make it available to C-code action routines, destructors,
+and so forth.  For example, if the grammar file contains:</p>
+
+<pre>
+    %extra_context { MyStruct *pAbc }
+</pre>
+
+<p>Then the ParseAlloc() and ParseInit() functions will have an 2nd parameter
+of type "MyStruct*" and all action routines will have access to
+a variable named "pAbc" that is the value of that 2nd parameter.</p>
+
+<p>The <tt>%extra_argument</tt> directive works the same except that it
+is passed in on the Parse() routine instead of on ParseAlloc()/ParseInit().</p>
+
+<a id='pfallback'></a>
+<h4>4.4.7 The <tt>%fallback</tt> directive</h4>
+
+<p>The <tt>%fallback</tt> directive specifies an alternative meaning for one
+or more tokens.  The alternative meaning is tried if the original token
+would have generated a syntax error.</p>
+
+<p>The <tt>%fallback</tt> directive was added to support robust parsing of SQL
+syntax in <a href='https://www.sqlite.org/'>SQLite</a>.
+The SQL language contains a large assortment of keywords, each of which
+appears as a different token to the language parser.  SQL contains so
+many keywords that it can be difficult for programmers to keep up with
+them all.  Programmers will, therefore, sometimes mistakenly use an
+obscure language keyword for an identifier.  The <tt>%fallback</tt> directive
+provides a mechanism to tell the parser:  "If you are unable to parse
+this keyword, try treating it as an identifier instead."</p>
+
+<p>The syntax of <tt>%fallback</tt> is as follows:</p>
+
+<blockquote>
+<tt>%fallback</tt> <i>ID</i> <i>TOKEN...</i> <b>.</b>
+</blockquote></p>
+
+<p>In words, the <tt>%fallback</tt> directive is followed by a list of token
+names terminated by a period.
+The first token name is the fallback token &mdash; the
+token to which all the other tokens fall back to.  The second and subsequent
+arguments are tokens which fall back to the token identified by the first
+argument.</p>
+
+<a id='pifdef'></a>
+<h4>4.4.8 The <tt>%if</tt> directive and its friends</h4>
+
+<p>The <tt>%if</tt>, <tt>%ifdef</tt>, <tt>%ifndef</tt>, <tt>%else</tt>,
+and <tt>%endif</tt> directives
+are similar to #if, #ifdef, #ifndef, #else, and #endif in the C-preprocessor,
+just not as general.
+Each of these directives must begin at the left margin.  No whitespace
+is allowed between the "%" and the directive name.</p>
+
+<p>Grammar text in between "<tt>%ifdef MACRO</tt>" and the next nested
+"<tt>%endif</tt>" is
+ignored unless the "-DMACRO" command-line option is used.  Grammar text
+betwen "<tt>%ifndef MACRO</tt>" and the next nested "<tt>%endif</tt>" is
+included except when the "-DMACRO" command-line option is used.<p>
+
+<p>The text in between "<tt>%if</tt> <i>CONDITIONAL</i>" and its
+corresponding <tt>%endif</tt> is included only if <i>CONDITIONAL</i>
+is true.  The CONDITION is one or more macro names, optionally connected
+using the "||" and "&amp;&amp;" binary operators, the "!" unary operator,
+and grouped using balanced parentheses.  Each term is true if the
+corresponding macro exists, and false if it does not exist.</p>
+
+<p>An optional "<tt>%else</tt>" directive can occur anywhere in between a 
+<tt>%ifdef</tt>, <tt>%ifndef</tt>, or <tt>%if</tt> directive and
+its corresponding <tt>%endif</tt>.</p>
+
+<p>Note that the argument to <tt>%ifdef</tt> and <tt>%ifndef</tt> is
+intended to be a single preprocessor symbol name, not a general expression.
+Use the "<tt>%if</tt>" directive for general expressions.</p>
+
+<a id='pinclude'></a>
+<h4>4.4.9 The <tt>%include</tt> directive</h4>
+
+<p>The <tt>%include</tt> directive specifies C code that is included at the
+top of the generated parser.  You can include any text you want &mdash;
+the Lemon parser generator copies it blindly.  If you have multiple
+<tt>%include</tt> directives in your grammar file, their values are concatenated
+so that all <tt>%include</tt> code ultimately appears near the top of the
+generated parser, in the same order as it appeared in the grammar.</p>
+
+<p>The <tt>%include</tt> directive is very handy for getting some extra #include
+preprocessor statements at the beginning of the generated parser.
+For example:</p>
+
+<pre>
+   %include {#include &lt;unistd.h&gt;}
+</pre>
+
+<p>This might be needed, for example, if some of the C actions in the
+grammar call functions that are prototyped in unistd.h.</p>
+
+<p>Use the <tt><a href="#pcode">%code</a></tt> directive to add code to
+the end of the generated parser.</p>
+
+<a id='pleft'></a>
+<h4>4.4.10 The <tt>%left</tt> directive</h4>
+
+The <tt>%left</tt> directive is used (along with the
+<tt><a href='#pright'>%right</a></tt> and
+<tt><a href='#pnonassoc'>%nonassoc</a></tt> directives) to declare
+precedences of terminal symbols.
+Every terminal symbol whose name appears after
+a <tt>%left</tt> directive but before the next period (".") is
+given the same left-associative precedence value.  Subsequent
+<tt>%left</tt> directives have higher precedence.  For example:</p>
+
+<pre>
+   %left AND.
+   %left OR.
+   %nonassoc EQ NE GT GE LT LE.
+   %left PLUS MINUS.
+   %left TIMES DIVIDE MOD.
+   %right EXP NOT.
+</pre>
+
+<p>Note the period that terminates each <tt>%left</tt>,
+<tt>%right</tt> or <tt>%nonassoc</tt>
+directive.</p>
+
+<p>LALR(1) grammars can get into a situation where they require
+a large amount of stack space if you make heavy use or right-associative
+operators.  For this reason, it is recommended that you use <tt>%left</tt>
+rather than <tt>%right</tt> whenever possible.</p>
+
+<a id='pname'></a>
+<h4>4.4.11 The <tt>%name</tt> directive</h4>
+
+<p>By default, the functions generated by Lemon all begin with the
+five-character string "Parse".  You can change this string to something
+different using the <tt>%name</tt> directive.  For instance:</p>
+
+<pre>
+   %name Abcde
+</pre>
+
+<p>Putting this directive in the grammar file will cause Lemon to generate
+functions named</p>
+<ul>
+<li> AbcdeAlloc(),
+<li> AbcdeFree(),
+<li> AbcdeTrace(), and
+<li> Abcde().
+</ul>
+</p>The <tt>%name</tt> directive allows you to generate two or more different
+parsers and link them all into the same executable.</p>
+
+<a id='pnonassoc'></a>
+<h4>4.4.12 The <tt>%nonassoc</tt> directive</h4>
+
+<p>This directive is used to assign non-associative precedence to
+one or more terminal symbols.  See the section on
+<a href='#precrules'>precedence rules</a>
+or on the <tt><a href='#pleft'>%left</a></tt> directive
+for additional information.</p>
+
+<a id='parse_accept'></a>
+<h4>4.4.13 The <tt>%parse_accept</tt> directive</h4>
+
+<p>The <tt>%parse_accept</tt> directive specifies a block of C code that is
+executed whenever the parser accepts its input string.  To "accept"
+an input string means that the parser was able to process all tokens
+without error.</p>
+
+<p>For example:</p>
+
+<pre>
+   %parse_accept {
+      printf("parsing complete!\n");
+   }
+</pre>
+
+<a id='parse_failure'></a>
+<h4>4.4.14 The <tt>%parse_failure</tt> directive</h4>
+
+<p>The <tt>%parse_failure</tt> directive specifies a block of C code that
+is executed whenever the parser fails complete.  This code is not
+executed until the parser has tried and failed to resolve an input
+error using is usual error recovery strategy.  The routine is
+only invoked when parsing is unable to continue.</p>
+
+<pre>
+   %parse_failure {
+     fprintf(stderr,"Giving up.  Parser is hopelessly lost...\n");
+   }
+</pre>
+
+<a id='pright'></a>
+<h4>4.4.15 The <tt>%right</tt> directive</h4>
+
+<p>This directive is used to assign right-associative precedence to
+one or more terminal symbols.  See the section on
+<a href='#precrules'>precedence rules</a>
+or on the <a href='#pleft'>%left</a> directive for additional information.</p>
+
+<a id='stack_overflow'></a>
+<h4>4.4.16 The <tt>%stack_overflow</tt> directive</h4>
+
+<p>The <tt>%stack_overflow</tt> directive specifies a block of C code that
+is executed if the parser's internal stack ever overflows.  Typically
+this just prints an error message.  After a stack overflow, the parser
+will be unable to continue and must be reset.</p>
+
+<pre>
+   %stack_overflow {
+     fprintf(stderr,"Giving up.  Parser stack overflow\n");
+   }
+</pre>
+
+<p>You can help prevent parser stack overflows by avoiding the use
+of right recursion and right-precedence operators in your grammar.
+Use left recursion and and left-precedence operators instead to
+encourage rules to reduce sooner and keep the stack size down.
+For example, do rules like this:</p>
+<pre>
+   list ::= list element.      // left-recursion.  Good!
+   list ::= .
+</pre>
+<p>Not like this:</p>
+<pre>
+   list ::= element list.      // right-recursion.  Bad!
+   list ::= .
+</pre>
+
+<a id='stack_size'></a>
+<h4>4.4.17 The <tt>%stack_size</tt> directive</h4>
+
+<p>If stack overflow is a problem and you can't resolve the trouble
+by using left-recursion, then you might want to increase the size
+of the parser's stack using this directive.  Put an positive integer
+after the <tt>%stack_size</tt> directive and Lemon will generate a parse
+with a stack of the requested size.  The default value is 100.</p>
+
+<pre>
+   %stack_size 2000
+</pre>
+
+<a id='start_symbol'></a>
+<h4>4.4.18 The <tt>%start_symbol</tt> directive</h4>
+
+<p>By default, the start symbol for the grammar that Lemon generates
+is the first non-terminal that appears in the grammar file.  But you
+can choose a different start symbol using the
+<tt>%start_symbol</tt> directive.</p>
+
+<pre>
+   %start_symbol  prog
+</pre>
+
+<a id='syntax_error'></a>
+<h4>4.4.19 The <tt>%syntax_error</tt> directive</h4>
+
+<p>See <a href='#errors'>Error Processing</a>.</p>
+
+<a id='token'></a>
+<h4>4.4.20 The <tt>%token</tt> directive</h4>
+
+<p>Tokens are normally created automatically, the first time they are used.
+Any identifier that begins with an upper-case letter is a token.
+
+<p>Sometimes it is useful to declare tokens in advance, however.  The
+integer values assigned to each token determined by the order in which
+the tokens are seen.  So by declaring tokens in advance, it is possible to
+cause some tokens to have low-numbered values, which might be desirable in
+some grammers, or to have sequential values assigned to a sequence of
+related tokens.  For this reason, the %token directive is provided to
+declare tokens in advance.  The syntax is as follows:
+
+<blockquote>
+<tt>%token</tt> <i>TOKEN</i> <i>TOKEN...</i> <b>.</b>
+</blockquote></p>
+
+<p>The %token directive is followed by zero or more token symbols and
+terminated by a single ".".  Each token named is created if it does not
+already exist.  Tokens are created in order.
+
+
+<a id='token_class'></a>
+<h4>4.4.21 The <tt>%token_class</tt> directive</h4>
+
+<p>Undocumented.  Appears to be related to the MULTITERMINAL concept.
+<a href='http://sqlite.org/src/fdiff?v1=796930d5fc2036c7&v2=624b24c5dc048e09&sbs=0'>Implementation</a>.</p>
+
+<a id='token_destructor'></a>
+<h4>4.4.22 The <tt>%token_destructor</tt> directive</h4>
+
+<p>The <tt>%destructor</tt> directive assigns a destructor to a non-terminal
+symbol.  (See the description of the
+<tt><a href='%destructor'>%destructor</a></tt> directive above.)
+The <tt>%token_destructor</tt> directive does the same thing
+for all terminal symbols.</p>
+
+<p>Unlike non-terminal symbols, which may each have a different data type
+for their values, terminals all use the same data type (defined by
+the <tt><a href='#token_type'>%token_type</a></tt> directive)
+and so they use a common destructor.
+Other than that, the token destructor works just like the non-terminal
+destructors.</p>
+
+<a id='token_prefix'></a>
+<h4>4.4.23 The <tt>%token_prefix</tt> directive</h4>
+
+<p>Lemon generates #defines that assign small integer constants
+to each terminal symbol in the grammar.  If desired, Lemon will
+add a prefix specified by this directive
+to each of the #defines it generates.</p>
+
+<p>So if the default output of Lemon looked like this:</p>
+<pre>
+    #define AND              1
+    #define MINUS            2
+    #define OR               3
+    #define PLUS             4
+</pre>
+<p>You can insert a statement into the grammar like this:</p>
+<pre>
+    %token_prefix    TOKEN_
+</pre>
+<p>to cause Lemon to produce these symbols instead:</p>
+<pre>
+    #define TOKEN_AND        1
+    #define TOKEN_MINUS      2
+    #define TOKEN_OR         3
+    #define TOKEN_PLUS       4
+</pre>
+
+<a id='token_type'></a><a id='ptype'></a>
+<h4>4.4.24 The <tt>%token_type</tt> and <tt>%type</tt> directives</h4>
+
+<p>These directives are used to specify the data types for values
+on the parser's stack associated with terminal and non-terminal
+symbols.  The values of all terminal symbols must be of the same
+type.  This turns out to be the same data type as the 3rd parameter
+to the Parse() function generated by Lemon.  Typically, you will
+make the value of a terminal symbol be a pointer to some kind of
+token structure.  Like this:</p>
+
+<pre>
+   %token_type    {Token*}
+</pre>
+
+<p>If the data type of terminals is not specified, the default value
+is "void*".</p>
+
+<p>Non-terminal symbols can each have their own data types.  Typically
+the data type of a non-terminal is a pointer to the root of a parse tree
+structure that contains all information about that non-terminal.
+For example:</p>
+
+<pre>
+   %type   expr  {Expr*}
+</pre>
+
+<p>Each entry on the parser's stack is actually a union containing
+instances of all data types for every non-terminal and terminal symbol.
+Lemon will automatically use the correct element of this union depending
+on what the corresponding non-terminal or terminal symbol is.  But
+the grammar designer should keep in mind that the size of the union
+will be the size of its largest element.  So if you have a single
+non-terminal whose data type requires 1K of storage, then your 100
+entry parser stack will require 100K of heap space.  If you are willing
+and able to pay that price, fine.  You just need to know.</p>
+
+<a id='pwildcard'></a>
+<h4>4.4.25 The <tt>%wildcard</tt> directive</h4>
+
+<p>The <tt>%wildcard</tt> directive is followed by a single token name and a
+period.  This directive specifies that the identified token should
+match any input token.</p>
+
+<p>When the generated parser has the choice of matching an input against
+the wildcard token and some other token, the other token is always used.
+The wildcard token is only matched if there are no alternatives.</p>
+
+<a id='reallc'></a>
+<h4>4.4.26 The <tt>%realloc</tt> and <tt>%free</tt> directives</h4>
+
+<p>The <tt>%realloc</tt> and <tt>%free</tt> directives defines function
+that allocate and free heap memory.  The signatures of these functions
+should be the same as the realloc() and free() functions from the standard
+C library.
+
+<p>If both of these functions are defined
+then these functions are used to allocate and free
+memory for supplemental parser stack space, if the initial
+parse stack space is exceeded.  The initial parser stack size
+is specified by either <tt>%stack_size</tt> or the
+-DYYSTACKDEPTH compile-time flag.
+
+<a id='errors'></a>
+<h2>5.0 Error Processing</h2>
+
+<p>After extensive experimentation over several years, it has been
+discovered that the error recovery strategy used by yacc is about
+as good as it gets.  And so that is what Lemon uses.</p>
+
+<p>When a Lemon-generated parser encounters a syntax error, it
+first invokes the code specified by the <tt>%syntax_error</tt> directive, if
+any.  It then enters its error recovery strategy.  The error recovery
+strategy is to begin popping the parsers stack until it enters a
+state where it is permitted to shift a special non-terminal symbol
+named "error".  It then shifts this non-terminal and continues
+parsing.  The <tt>%syntax_error</tt> routine will not be called again
+until at least three new tokens have been successfully shifted.</p>
+
+<p>If the parser pops its stack until the stack is empty, and it still
+is unable to shift the error symbol, then the
+<tt><a href='#parse_failure'>%parse_failure</a></tt> routine
+is invoked and the parser resets itself to its start state, ready
+to begin parsing a new file.  This is what will happen at the very
+first syntax error, of course, if there are no instances of the
+"error" non-terminal in your grammar.</p>

+     being deleted, truncated, or zeroed.
+ 
+ (6) If a master journal file is used, then all writes to the database file
+     are synced prior to the master journal being deleted.

+ *** Definition: Two databases (or the same database at two points it time)
+     are said to be "logically equivalent" if they give the same answer to

+ 
+ (8) When a transaction is rolled back, the xTruncate method of the VFS
+     is called to restore the database file to the same size it was at
+     the beginning of the transaction.  (In some VFSes, the xTruncate
+     method is a no-op, but that does not change the fact the SQLite will

+     than one billion transactions.
+
+(11) A database file is well-formed at the beginning and at the conclusion

+
+(12) An EXCLUSIVE lock must be held on the database file before making

+# 1. Overview
+
+testrunner.tcl is a Tcl script used to run multiple SQLite tests using 
+multiple jobs. It supports the following types of tests:
+
+  *  Tcl test scripts.
+
+  *  Tests run with `make` commands.  Examples:
+      -  `make mdevtest`
+      -  `make releasetest`
+      -  `make sdevtest`
+      -  `make testrunner`
+
+testrunner.tcl pipes the output of all tests and builds run into log file
+**testrunner.log**, created in the current working directory. Search this
+file to find details of errors.  Suggested search commands:
+
+   *  `grep "^!" testrunner.log`
+   *  `grep failed testrunner.log`
+
+testrunner.tcl also populates SQLite database **testrunner.db**. This database
+contains details of all tests run, running and to be run. A useful query
+might be:
+
+```
+  SELECT * FROM script WHERE state='failed'
+```
+
+Running the command:
+
+```
+  ./testfixture $(TESTDIR)/testrunner.tcl status
+```
+
+in the directory containing the testrunner.db database runs various queries
+to produce a succinct report on the state of a running testrunner.tcl script.
+Running:
+
+```
+  watch ./testfixture $(TESTDIR)/testrunner.tcl status
+```
+
+in another terminal is a good way to keep an eye on a long running test.
+
+Sometimes testrunner.tcl uses the `testfixture` binary that it is run with
+to run tests (see "Binary Tests" below). Sometimes it builds testfixture and
+other binaries in specific configurations to test (see "Source Tests").
+
+<a name=binary_tests></a>
+# 2. Binary Tests
+
+The commands described in this section all run various combinations of the Tcl
+test scripts using the `testfixture` binary used to run the testrunner.tcl
+script (i.e. they do not invoke the compiler to build new binaries, or the
+`make` command to run tests that are not Tcl scripts). The procedure to run
+these tests is therefore:
+
+  1. Build the "testfixture" (or "testfixture.exe" for windows) binary using
+     whatever method seems convenient.
+
+  2. Test the binary built in step 1 by running testrunner.tcl with it, 
+     perhaps with various options.
+
+The following sub-sections describe the various options that can be
+passed to testrunner.tcl to test binary testfixture builds.
+
+<a name=organization_tests></a>
+## 2.1. Organization of Tcl Tests
+
+Tcl tests are stored in files that match the pattern *\*.test*. They are
+found in both the $TOP/test/ directory, and in the various sub-directories
+of the $TOP/ext/ directory of the source tree. Not all *\*.test* files
+contain Tcl tests - a handful are Tcl scripts designed to invoke other
+*\*.test* files.
+
+The **veryquick** set of tests is a subset of all Tcl test scripts in the
+source tree. In includes most tests, but excludes some that are very slow.
+Almost all fault-injection tests (those that test the response of the library
+to OOM or IO errors) are excluded. It is defined in source file 
+*test/permutations.test*.
+
+The **full** set of tests includes all Tcl test scripts in the source tree.
+To run a "full" test is to run all Tcl test scripts that can be found in the
+source tree.
+
+File *permutations.test* defines various test "permutations". A permutation
+consists of:
+
+  *  A subset of Tcl test scripts, and 
+
+  *  Runtime configuration to apply before running each test script 
+     (e.g. enabling auto-vacuum, or disable lookaside).
+
+Running **all** tests is to run all tests in the full test set, plus a dozen
+or so permutations. The specific permutations that are run as part of "all"
+are defined in file *testrunner_data.tcl*.
+
+<a name=run_tests></a>
+## 2.2. Commands to Run Tests
+
+To run the "veryquick" test set, use either of the following:
+
+```
+  ./testfixture $TESTDIR/testrunner.tcl
+  ./testfixture $TESTDIR/testrunner.tcl veryquick
+```
+
+To run the "full" test suite:
+
+```
+  ./testfixture $TESTDIR/testrunner.tcl full
+```
+
+To run the subset of the "full" test suite for which the test file name matches
+a specified pattern (e.g. all tests that start with "fts5"), either of:
+
+```
+  ./testfixture $TESTDIR/testrunner.tcl fts5%
+  ./testfixture $TESTDIR/testrunner.tcl 'fts5*'
+```
+
+Strictly speaking, for a test to be run the pattern must match the script
+filename, not including the directory, using the rules of Tcl's 
+\[string match\] command. Except that before the matching is done, any "%"
+characters specified as part of the pattern are transformed to "\*".
+
+
+To run "all" tests (full + permutations):
+
+```
+  ./testfixture $TESTDIR/testrunner.tcl all
+```
+
+<a name=binary_test_failures></a>
+## 2.3. Investigating Binary Test Failures
+
+If a test fails, testrunner.tcl reports name of the Tcl test script and, if
+applicable, the name of the permutation, to stdout. This information can also
+be retrieved from either *testrunner.log* or *testrunner.db*.
+
+If there is no permutation, the individual test script may be run with:
+
+```
+  ./testfixture $PATH_TO_SCRIPT
+```
+
+Or, if the failure occured as part of a permutation:
+
+```
+  ./testfixture $TESTDIR/testrunner.tcl $PERMUTATION $PATH_TO_SCRIPT
+```
+
+TODO: An example instead of "$PERMUTATION" and $PATH\_TO\_SCRIPT?
+
+<a name=source_code_tests></a>
+# 3. Source Code Tests
+
+The commands described in this section invoke the C compiler to build 
+binaries from the source tree, then use those binaries to run Tcl and
+other tests. The advantages of this are that:
+
+  *  it is possible to test multiple build configurations with a single
+     command, and 
+
+  *  it ensures that tests are always run using binaries created with the
+     same set of compiler options.
+
+The testrunner.tcl commands described in this section may be run using
+either a *testfixture* (or testfixture.exe) build, or with any other Tcl
+shell that supports SQLite 3.31.1 or newer via "package require sqlite3".
+
+TODO: ./configure + Makefile.msc build systems.
+
+<a name=commands_to_run_tests></a>
+## 3.1. Commands to Run SQLite Tests
+
+The **mdevtest** command is equivalent to running the veryquick tests and
+the `make fuzztest` target once for each of two --enable-all builds - one 
+with debugging enabled and one without:
+
+```
+  tclsh $TESTDIR/testrunner.tcl mdevtest
+```
+
+In other words, it is equivalent to running:
+
+```
+  $TOP/configure --enable-all --enable-debug
+  make fuzztest
+  make testfixture
+  ./testfixture $TOP/test/testrunner.tcl veryquick
+
+  # Then, after removing files created by the tests above:
+  $TOP/configure --enable-all OPTS="-O0"
+  make fuzztest
+  make testfixture
+  ./testfixture $TOP/test/testrunner.tcl veryquick
+```
+
+The **sdevtest** command is identical to the mdevtest command, except that the
+second of the two builds is a sanitizer build. Specifically, this means that
+OPTS="-fsanitize=address,undefined" is specified instead of OPTS="-O0":
+
+```
+  tclsh $TESTDIR/testrunner.tcl sdevtest
+```
+
+The **release** command runs lots of tests under lots of builds. It runs
+different combinations of builds and tests depending on whether it is run
+on Linux, Windows or OSX. Refer to *testrunner\_data.tcl* for the details
+of the specific tests run.
+
+```
+  tclsh $TESTDIR/testrunner.tcl release
+```
+
+As with <a href=#source code tests>source code tests</a>, one or more patterns
+may be appended to any of the above commands (mdevtest, sdevtest or release).
+In that case only Tcl tests (no fuzz or other tests) that match the specified
+pattern are run. For example, to run the just the Tcl rtree tests in all 
+builds and configurations supported by "release":
+
+```
+  tclsh $TESTDIR/testrunner.tcl release rtree%
+```
+
+<a name=zipvfs_tests></a>
+## 3.2. Running ZipVFS Tests
+
+testrunner.tcl can build a zipvfs-enabled testfixture and use it to run
+tests from the Zipvfs project with the following command:
+
+```
+  tclsh $TESTDIR/testrunner.tcl --zipvfs $PATH_TO_ZIPVFS
+```
+
+This can be combined with any of "mdevtest", "sdevtest" or "release" to
+test both SQLite and Zipvfs with a single command:
+
+```
+  tclsh $TESTDIR/testrunner.tcl --zipvfs $PATH_TO_ZIPVFS mdevtest
+```
+
+<a name=source_code_test_failures></a>
+## 3.3. Investigating Source Code Test Failures
+
+Investigating a test failure that occurs during source code testing is a
+two step process:
+
+  1. Recreating the build configuration in which the test failed, and
+
+  2. Re-running the actual test.
+
+To recreate a build configuration, use the testrunner.tcl **script** command
+to create a build script. A build script is a bash script on Linux or OSX, or
+a dos \*.bat file on windows. For example:
+
+```
+  # Create a script that recreates build configuration "Device-One" on 
+  # Linux or OSX:
+  tclsh $TESTDIR/testrunner.tcl script Device-One > make.sh 
+
+  # Create a script that recreates build configuration "Have-Not" on Windows:
+  tclsh $TESTDIR/testrunner.tcl script Have-Not > make.bat 
+```
+
+The generated bash or \*.bat file script accepts a single argument - a makefile
+target to build. This may be used either to run a `make` command test directly,
+or else to build a testfixture (or testfixture.exe) binary with which to
+run a Tcl test script, as <a href=#binary_test_failures>described above</a>.
+
+<a name=testrunner_options></a>
+# 4. Extra testrunner.tcl Options
+
+The testrunner.tcl script options in this section may be used with both source
+code and binary tests.
+
+The **--buildonly** option instructs testrunner.tcl just to build the binaries
+required by a test, not to run any actual tests. For example:
+
+```
+  # Build binaries required by release test.
+  tclsh $TESTDIR/testrunner.tcl --buildonly release"
+```
+
+The **--dryrun** option prevents testrunner.tcl from building any binaries
+or running any tests. Instead, it just writes the shell commands that it
+would normally execute into the testrunner.log file. Example:
+
+```
+  # Log the shell commmands that make up the mdevtest test.
+  tclsh $TESTDIR/testrunner.tcl --dryrun mdevtest"
+```
+
+The **--explain** option is similar to --dryrun in that it prevents testrunner.tcl
+from building any binaries or running any tests.  The difference is that --explain
+prints on standard output a human-readable summary of all the builds and tests that
+would have been run.
+
+```
+  # Show what builds and tests would have been run
+  tclsh $TESTDIR/testrunner.tcl --explain mdevtest
+```
+
+<a name=cpu_cores></a>
+# 5. Controlling CPU Core Utilization
+
+When running either binary or source code tests, testrunner.tcl reports the
+number of jobs it intends to use to stdout. e.g.
+
+```
+  $ ./testfixture $TESTDIR/testrunner.tcl
+  splitting work across 16 jobs
+  ... more output ...
+```
+
+By default, testfixture.tcl attempts to set the number of jobs to the number 
+of real cores on the machine. This can be overridden using the "--jobs" (or -j)
+switch:
+
+```
+  $ ./testfixture $TESTDIR/testrunner.tcl --jobs 8
+  splitting work across 8 jobs
+  ... more output ...
+```
+
+The number of jobs may also be changed while an instance of testrunner.tcl is
+running by exucuting the following command from the directory containing the
+testrunner.log and testrunner.db files:
+
+```
+  $ ./testfixture $TESTDIR/testrunner.tcl njob $NEW_NUMBER_OF_JOBS
+```

+# The new-security-options branch
+
+## The problem that the [new-security-options](/timeline?r=new-security-options) branch tries to solve
+
+An attacker might modify the schema of an SQLite database by adding
+structures that cause code to run when some other application opens and
+reads the database.  For example, the attacker might replace a table
+definition with a view.  Or the attacker might add triggers to tables
+or views, or add new CHECK constraints or generated columns or indexes
+with expressions in the index list or in the WHERE clause.  If the
+added features invoke SQL functions or virtual tables with side effects,
+that might cause harm to the system if run by a high-privilege victim.
+Or, the added features might exfiltrate information if the database is
+read by a high-privilege victim.
+
+The changes in this branch strive to make it easier for high-privilege
+applications to safely read SQLite database files that might have been
+maliciously corrupted by an attacker.
+
+## Overview of changes in [new-security-options](/timeline?r=new-security-options)
+
+The basic idea is to tag every SQL function and virtual table with one
+of three risk levels:
+
+  1.  Innocuous
+  2.  Normal
+  3.  Direct-Only
+
+Innocuous functions/vtabs are safe and can be used at any time.
+Direct-only elements, in contrast, might have cause side-effects and
+should only be used from top-level SQL, not from within triggers or views nor
+in elements of the schema such as CHECK constraint, DEFAULT values, 
+generated columns, index expressions, or in the WHERE clause of a 
+partial index that are potentially under the control of an attacker.
+Normal elements behave like Innocuous if TRUSTED\_SCHEMA=on
+and behave like direct-only if TRUSTED\_SCHEMA=off.
+
+Application-defined functions and virtual tables go in as Normal unless
+the application takes deliberate steps to change the risk level.
+
+For backwards compatibility, the default is TRUSTED\_SCHEMA=on.  Documentation
+will be updated to recommend applications turn TRUSTED\_SCHEMA to off.
+
+An innocuous function or virtual table is one that can only read content
+from the database file in which it resides, and can only alter the database
+in which it resides.  Most SQL functions are innocuous.  For example, there
+is no harm in an attacker running the abs() function.
+
+Direct-only elements that have side-effects that go outside the database file
+in which it lives, or return information from outside of the database file.
+Examples of direct-only elements include:
+
+  1.  The fts3\_tokenizer() function
+  2.  The writefile() function
+  3.  The readfile() function
+  4.  The zipvfs virtual table
+  5.  The csv virtual table
+
+We do not want an attacker to be able to add these kinds of things to
+the database schema and possibly trick a high-privilege application 
+from performing any of these actions.  Therefore, functions and vtabs
+with side-effects are marked as Direct-Only.
+
+Legacy applications might add other risky functions or vtabs.  Those will
+go in as "Normal" by default.  For optimal security, we want those risky
+app-defined functions and vtabs to be direct-only, but making that the
+default might break some legacy applications.  Hence, all app-defined
+functions and vtabs go in as Normal, but the application can switch them
+over to "Direct-Only" behavior using a single pragma.
+
+The restrictions on the use of functions and virtual tables do not apply
+to TEMP.  A TEMP VIEW or a TEMP TRIGGER can use any valid SQL function
+or virtual table.  The idea is that TEMP views and triggers must be
+directly created by the application and are thus under the control of the
+application.  TEMP views and triggers cannot be created by an attacker who
+corrupts the schema of a persistent database file.  Hence TEMP views and
+triggers are safe.
+
+## Specific changes
+
+  1.  New sqlite3\_db\_config() option SQLITE\_DBCONFIG\_TRUSTED\_SCHEMA for
+      turning TRUSTED\_SCHEMA on and off.  It defaults to ON.
+
+  2.  Compile-time option -DSQLITE\_TRUSTED\_SCHEMA=0 causes the default
+      TRUSTED\_SCHEMA setting to be off.
+
+  3.  New pragma "PRAGMA trusted\_schema=(ON\|OFF);".  This provides access
+      to the TRUSTED_SCHEMA setting for application coded using scripting
+      languages or other secondary languages where they are unable to make
+      calls to sqlite3\_db\_config().
+
+  4.  New options for the "enc" parameter to sqlite3\_create\_function() and
+      its kin:
+      <ol type="a">
+      <li>  _SQLITE\_INNOCUOUS_  &rarr; tags the new functions as Innocuous
+      <li>  _SQLITE\_DIRECTONLY_ &rarr; tags the new functions as Direct-Only
+      </ol>
+
+  5.  New options to sqlite3\_vtab\_config():
+      <ol type="a">
+      <li>  _SQLITE\_VTAB\_INNOCUOUS_   &rarr; tags the vtab as Innocuous
+      <li>  _SQLITE\_VTAB\_DIRECTONLY_  &rarr; tags the vtab as Direct-Only
+      </ol>
+
+  6.  Change many of the functions and virtual tables in the SQLite source
+      tree to use one of the tags above.
+
+  7.  Enhanced PRAGMA function\_list and virtual-table "pragma\_function\_list"
+      with additional columns.  The columns now are:
+      <ul>
+      <li> _name_      &rarr;  Name of the function
+      <li> _builtin_   &rarr;  1 for built-in functions.  0 otherwise.
+      <li> _type_      &rarr;  's'=Scalar, 'a'=Aggregate, 'w'=Window
+      <li> _enc_       &rarr;  'utf8', 'utf16le', or 'utf16be'
+      <li> _narg_      &rarr;  number of argument
+      <li> _flags_     &rarr;  Bitmask of SQLITE\_INNOCUOUS, SQLITE\_DIRECTONLY,
+                               SQLITE\_DETERMINISTIC, SQLITE\_SUBTYPE, and
+                               SQLITE\_FUNC\_INTERNAL flags.
+      </ul>
+      <p>The last four columns are new.
+
+  8.  The function\_list PRAGMA now also shows all entries for each function.
+      So, for example, if a function can take either 2 or 3 arguments,
+      there are separate rows for the 2-argument and 3-argument versions of
+      the function.
+
+## Additional Notes
+
+The function_list enhancements allow the application to query the set
+of SQL functions that meet various criteria.  For example, to see all
+SQL functions that are never allowed to be used in the schema or in
+trigger or views:
+
+~~~
+    SELECT DISTINCT name FROM pragma_function_list
+     WHERE (flags & 0x80000)!=0
+     ORDER BY name;
+~~~
+
+Doing the same is not possible for virtual tables, as a virtual table
+might be Innocuous, Normal, or Direct-Only depending on the arguments
+passed into the xConnect method.

+# Memory Allocation In vdbesort.c
+
+Memory allocation is slightly different depending on:
+
+  * whether or not SQLITE_CONFIG_SMALL_MALLOC is set, and
+  * whether or not worker threads are enabled.
+
+## SQLITE_CONFIG_SMALL_MALLOC=0
+
+Assuming SQLITE_CONFIG_SMALL_MALLOC is not set, keys passed to the sorter are
+added to an in-memory buffer. This buffer is grown using sqlite3Realloc() as
+required it reaches the size configured for the main pager cache using "PRAGMA
+cache_size". i.e. if the user has executed "PRAGMA main.cache_size = -2048",
+then this buffer is allowed to grow up to 2MB in size.
+
+Once the buffer has grown to its threshold, keys are sorted and written to
+a temp file. If worker threads are not enabled, this is the only significant
+allocation the sorter module makes. After keys are sorted and flushed out to
+the temp file, the buffer is reused to accumulate the next batch of keys.
+
+If worker threads are available, then the buffer is passed to a worker thread
+to sort and flush once it is full, and a new buffer allocated to allow the
+main thread to continue to accumulate keys. Buffers are reused once they
+have been flushed, so in this case at most (nWorker+1) buffers are allocated
+and used, where nWorker is the number of configured worker threads.
+
+There are no other significant users of heap memory in the sorter module. 
+Once sorted buffers of keys have been flushed to disk, they are read back
+either by mapping the file (via sqlite3_file.xFetch()) or else read back
+in one page at a time.
+
+All buffers are allocated by the main thread. A sorter object is associated
+with a single database connection, to which it holds a pointer.
+
+## SQLITE_CONFIG_SMALL_MALLOC=1
+
+This case is similar to the above, except that instead of accumulating
+multiple keys in a single large buffer, sqlite3VdbeSorterWrite() stores
+keys in a regular heap-memory linked list (one allocation per element).
+List elements are freed as they are flushed to disk, either by the main
+thread or by a worker thread.
+
+Each time a key is added the sorter (and an allocation made),
+sqlite3HeapNearlyFull() is called. If it returns true, the current
+list of keys is flushed to a temporary file, even if it has not yet
+reached the size threshold.
