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.
Use of GNU M4 is beyond the scope of this page. Please refer to the GNU M4 User Guide for information on usage.
