/**
 * JSMin.php - modified PHP implementation of Douglas Crockford's JSMin.
 *
 * <code>
 * $minifiedJs = JSMin::minify($js);
 * </code>
 *
 * This is a modified port of jsmin.c. Improvements:
 *
 * Does not choke on some regexp literals containing quote characters. E.g. /'/
 *
 * Spaces are preserved after some add/sub operators, so they are not mistakenly
 * converted to post-inc/dec. E.g. a + ++b -> a+ ++b
 *
 * Preserves multi-line comments that begin with /*!
 *
 * PHP 5 or higher is required.
