description="
Traditional Unix macro processor.

GNU M4 is an implementation of the traditional Unix macro processor.
It is mostly SVR4 compatible although it has some extensions (for
example, handling more than 9 positional parameters to macros).

GNU M4 also has built-in functions for including files, running shell
commands, doing arithmetic, etc.

GNU M4 is a macro processor in the sense that it copies its input
to the output expanding macros as it goes.
