Perl extension for minifying JavaScript code

This module removes unnecessary whitespace from JavaScript code. The
primary requirement developing this module is to not break working
code: if working JavaScript is in input then working JavaScript is
output. It is ok if the input has missing semi-colons, snips like '++
+' or '12 .toString()', for example. Internet Explorer conditional
comments are copied to the output but the code inside these comments
will not be minified.
