%description
    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).
    m4 also has builtin functions for including files, running shell
    commands, doing arithmetic, etc.
