description     GNU macro processor

long_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 built-in functions for including files,   \
    running shell commands, doing arithmetic, etc. Autoconf needs GNU   \
    `m4' for generating `configure' scripts, but not for running them.
