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