pkg-config is a system for managing library compile/link flags that works with automake and autoconf. It replaces the ubiquitous *-config scripts you may have seen with a single tool.
Release Notes: Lib flags are now kept in context. Aggressive removal of duplicate arguments was scaled down. An old bug preventing circular requires was fixed. Many corner case bugs and some ambiguous behaviors were eliminated. Other minor modifications and fixes were made.
