This is a direct port of jsmin.c to PHP with a few PHP performance tweaks and modifications to preserve some comments (see below). Also, rather than using stdin/stdout, JSMin::minify() accepts a string as input and returns another string as output.

Comments containing IE conditional compilation are preserved, as are multi-line comments that begin with "/*!" (for documentation purposes). In the latter case newlines are inserted around the comment to enhance readability.

PHP 5 or higher is required.
