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.

GNU M4 is a macro processor in the sense that it copies its input to the
output expanding macros as it goes. Macros are either builtin or user-
defined and can take any number of arguments. Besides just doing macro
expansion, m4 has builtin functions for including named files, running
UNIX commands, doing integer arithmetic, manipulating text in various
ways, recursion etc... m4 can be used either as a front-end to a compiler
or as a macro processor in its own right.
