<h2 class="chapter">Functions for Transforming Text</h2>

   <p><dfn>Functions</dfn> allow you to do text processing in the makefile to compute
the files to operate on or the commands to use.  You use a function in a
<dfn>function call</dfn>, where you give the name of the function and some text
(the <dfn>arguments</dfn>) for the function to operate on.  The result of the
function's processing is substituted into the makefile at the point of the
call, just as a variable might be substituted.
