+%description
+A GNU implementation of the traditional UNIX macro processor. M4 is
+useful for writing text files which can be logically parsed, and is used
+by many programs as part of their build process. M4 has built-in
+functions for including files, running shell commands, doing arithmetic,
+etc. The autoconf program needs m4 for generating configure scripts, but
+not for running configure scripts.
+
+Install m4 if you need a macro processor.
