-Perltidy reads a perl script and writes an indented, reformatted script.
-This document describes the parameters available for controlling this formatting.
+Perltidy reads a perl script and writes an indented, reformatted script.  The
+formatting process involves converting the script into a string of tokens,
+removing any non-essential whitespace, and then rewriting the string of tokens
+with whitespace using whatever rules are specified, or defaults.  This happens
+in a series of operations which can be controlled with the parameters described
+in this document.
