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.

For more information about m4 itself, read the README file included in the
archive, or look at this website: http://www.gnu.org/software/m4/
