Latest version: 1.1

A collection of M4 macros for build systems managed by GNU autotools. The macros test whether a particular program, library, or other dependency is available on the installing machine at build time. The autotool programs use the macros to generate a configure script that runs on most UNIX-based machines to build software packages.

A gentle introduction to GNU autotools can be found in the autobook. For detailed information on using M4 macros with autotools, see the autoconf manual.

Refer to the ChangeLog for recent library activity.
