| $css | string | |
| $options | array | 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.:
array('//symlink' => '/real/target/path') // unix
array('//static' => 'D:\\staticStorage') // Windows
'docRoot': (default = $_SERVER['DOCUMENT_ROOT'])
