pkg-config 0.28 Description:
pkg-config is an open source and completely free command-line program, a helper tool that is used automatically by the GCC (GNU Compiler Collection) project when compiling libraries and applications under a GNU/Linux or UNIX-like operating system. The software has been engineered in such a way that it can handle library links and compile flags which work with both the autoconf and automake tools. It is designed to replace the universal *-config scripts and it’s language-agnostic. pkg-config boasts a wide range of command-line options, which can be viewed at a glance by running the ‘pkg-config --help’ command after installation (see out ‘Getting started with pkg-config’ section below for details).
