+=head1 NAME
+
+CSS::Minifier - Perl extension for minifying CSS
+
+=head1 SYNOPSIS
+
+To minify a CSS file and have the output written directly to another file
+
+ use CSS::Minifier qw(minify);
+ open(INFILE, 'myStylesheet.css') or die;
+ open(OUTFILE, 'myStylesheet.css') or die;
+ minify(input => *INFILE, outfile => *OUTFILE);
+ close(INFILE);
+ close(OUTFILE);
+
+To minify a CSS string literal. Note that by omitting the outfile parameter a the minified code is returned as a string.
+
+ my minifiedCSS = minify(input => 'div {font-family: serif;}');
+
+To include a copyright comment at the top of the minified code.
+
+ minify(input => 'div {font-family: serif;}', copyright => 'BSD License');
+
+The "input" parameter is manditory. The "output" and "copyright" parameters are optional and can be used in any combination.
+
+=head1 DESCRIPTION
+
+This module removes unnecessary whitespace from CSS. The primary requirement developing this module is to not break working stylesheets: if working CSS is in input then working CSS is output. The Mac/Internet Explorer comment hack will be minimized but not stripped and so will continue to function.
+
+This module understands space, horizontal tab, new line, carriage return, and form feed characters to be whitespace. Any other characters that may be considered whitespace are not minimized. These other characters include paragraph separator and vertical tab.
+
+For static CSS files, it is recommended that you minify during the build stage of web deployment. If you minify on-the-fly then it might be a good idea to cache the minified file. Minifying static files on-the-fly repeatedly is wasteful.
+
+=head2 EXPORT
+
+None by default.
+
+Exportable on demand: minifiy()
+
+
+=head1 SEE ALSO
+
+This project is developed using an SVN repository. To check out the repository
+svn co http://dev.michaux.ca/svn/random/CSS-Minifier
