<para>M4 is a macro processor. It copies input to output, expanding
|
|
macros as it goes. Macros are either built-in or user-defined and can
|
|
take any number of arguments. Besides just doing macro expansion, m4
|
|
has built-in functions for including named files, running Unix
|
|
commands, doing integer arithmetic, manipulating text in various ways,
|
|
recursion, etc. The m4 program can be used either as a front-end to a
|
|
compiler or as a macro processor in its own right.</para>
