          <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>
