+      GNU Autoconf is an extensible package of M4 macros that produce
+      shell scripts to automatically configure software source code
+      packages.  These scripts can adapt the packages to many kinds of
+      UNIX-like systems without manual user intervention.  Autoconf
+      creates a configuration script for a package from a template
+      file that lists the operating system features that the package
+      can use, in the form of M4 macro calls.
