-pkg-config provides a way to link to libraries independent of a particular system's directory heirarchy.
+pkg-config is the querying interface to the _man(`pc(5)') file format,
+which stores metadata relating to the file locations of key files for a language compiler or interpreter.
+Its purpose is to facilitate library linking, particularly for C and C++,
+without knowledge of where exactly a library's files are stored,
+which can vary dramatically between system and package manager.

-The relevant manual pages on NetBSD are <CODE>pkgconf(1)</CODE>, <CODE>pc(5)</CODE>, and <CODE>pkg.m4(7)</CODE>.
+Another implementation of pkg-config, _man(`pkgconf(1)'), is the default on _ref(`#netbsd').
+_man(`pkgconf(1)') comes with _man(`pkg.m4(7)'), macros for GNU autoconf.
