# constituent parts.
#
# No arguments are required.  This script determines the location
# of its input files relative to the location of the script itself.
# This script should be tool/mkshellc.tcl.  If the directory holding
# the script is $DIR, then the component parts are located in $DIR/../src
# and $DIR/../ext/misc.

** This file is automatically generated by the script in the canonical
** SQLite source tree at tool/mkshellc.tcl.  That script combines source
** code from various constituent source files of SQLite into this single
** "shell.c" file used to implement the SQLite command-line shell.
**
** Most of the code found below comes from the "src/shell.c.in" file in
** the canonical SQLite source tree.  That main file contains "INCLUDE"
** lines that specify other files in the canonical source tree that are
** inserted to getnerate this complete program source file.
**
** The code from multiple files is combined into this single "shell.c"
** source file to help make the command-line program easier to compile.
**
** To modify this program, get a copy of the canonical SQLite source tree,
** edit the src/shell.c.in" and/or some of the other files that are included
** by "src/shell.c.in", then rerun the tool/mkshellc.tcl script.
