<sect4><title>m4</title>
<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>
