+ * @param array $options available options:
+ *
+ * 'preserveComments': (default true) multi-line comments that begin
+ * with "/*!" 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 "//" to substitute
+ * the doc root in the link paths (the array keys). E.g.:
+ * <code>
+ * array('//symlink' => '/real/target/path') // unix
+ * array('//static' => 'D:\\staticStorage') // Windows
+ * </code>
+ *
+ * 'docRoot': (default = $_SERVER['DOCUMENT_ROOT'])
