   (description
    "GNU M4 is an implementation of the M4 macro language, which features
some extensions over other implementations.  It is used as a macro processor,
which means it processes text, expanding macros as it encounters them.  It
also has some built-in functionns, for example to run shell commands or to do
arithmetic.")
