|

*
|
||||
* '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>
|
