Query: A good starting point

The GNU build system comprises the GNU utility programs Autoconf, Automake, and Libtool, and are well covered in this book. Other related tools frequently used with the GNU build system are GNU's make program, GNU gettext, pkg-config, and the GNU Compiler Collection, also called GCC, but they are not covered in this book.This book will be very useful if you are a novice in the GNU build system. You can read the book from first to last page, to get the confidence in such a perplexing system. We have read this book with my team mate and it was a great starting point for us. Since that, the book was of little use for us. But it was worth its price.
