pkg-config 0.20

pkg-config is a helper tool used when compiling applications and libraries. It helps you insert the correct compiler options on the command line so an application can use gcc -o test test.c `pkg-config --libs --cflags glib-2.0` for instance, rather than hard-coding values on where to find glib (or other libraries). It is language-agnostic, so it can be used for defining the location of documentation tools, for instance.
The program free software and licensed under the [WWW]GPL version 2 or any later version (at your option).
pkg-config works on multiple platforms: Linux and other UNIX-like operating systems, Mac OS X and Windows. It does not require anything but a reasonably well working C compiler and a C library, but can use an installed glib if that is present. (A copy of glib 1.2.8 is shipped together with pkg-config and this is sufficient for pkg-config to compile and work properly.)
The first implementation was written in shell, by James Henstridge. Later, it was rewritten in C by Havoc Pennington. It also grew an autoconf macro written by Tim Janik, later rewritten by Scott James Remnant.
Enhancements:
- Segfaults were fixed.
- Win32 fixes were made.
- The --short-errors option was added, and is now used by pkg.m4 if available.
- This gives a better error message if some libraries cant be found.
