	 * Minify a CSS string
	 *
	 * @param string $css
	 *
	 * @param array $options available options:
	 *
	 * 'preserveComments': (default true) multi-line comments that begin
	 * with &quot;/*!&quot; will be preserved with newlines before and after to
	 * enhance readability.
	 *
	 * 'removeCharsets': (default true) remove all @charset at-rules
	 *
	 * 'prependRelativePath': (default null) if given, this string will be
	 * prepended to all relative URIs in import/url declarations
	 *
	 * 'currentDir': (default null) if given, this is assumed to be the
	 * directory of the current CSS file. Using this, minify will rewrite
	 * all relative URIs in import/url declarations to correctly point to
	 * the desired files. For this to work, the files *must* exist and be
	 * visible by the PHP process.
	 *
	 * 'symlinks': (default = array()) If the CSS file is stored in
	 * a symlink-ed directory, provide an array of link paths to
	 * target paths, where the link paths are within the document root. Because
	 * paths need to be normalized for this to work, use &quot;//&quot; to substitute
	 * the doc root in the link paths (the array keys). E.g.:
	 * &lt;code&gt;
	 * array('//symlink' =&gt; '/real/target/path') // unix
	 * array('//static' =&gt; 'D:\\staticStorage')  // Windows
	 * &lt;/code&gt;
	 *
	 * 'docRoot': (default = $_SERVER['DOCUMENT_ROOT'])
	 * see Minify_CSS_UriRewriter::rewrite
	 *
	 * @return string
