<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></sect4>
