<para>copies the given files while expanding the macros that they
contain. These macros are either built-in or user-defined and can take
any number of arguments. Besides performing macro expansion,
<command>m4</command> has
built-in functions for including named files, running Unix commands,
performing integer arithmetic, manipulating text, recursion, etc. The
<command>m4</command> program can be used either as a front-end to a compiler or as a
macro processor in its own right.</para>
