1GNU `m4' is an implementation of the traditional Unix macro
2processor.  It is mostly SVR4 compatible, although it has some
3extensions (for example, handling more than 9 positional parameters
4to macros).  `m4' also has builtin functions for including files,
5running shell commands, doing arithmetic, etc.  Autoconf needs GNU
6`m4' for generating `configure' scripts, but not for running them.
8GNU `m4' was originally written by Rene' Seindal, from Denmark.
10GNU `m4' has a web site at http://www.gnu.org/software/m4/.
