Supported methods are: +* ```php```: Creates valid PHP files which can be included without any changes (default method). +* ```var_export```: Like "php", but using PHP's ```var_export()``` function without any optimizations. + It's recommended to use "php" instead. +* ```serialize```: Faster, but pretty memory-intense. +* ```callback```: Use custom callback functions to implement your own caching method. Give the "cache_callback_get" and + "cache_callback_set" options with callables (see PHP's ```call_user_func()``` and ```is_callable()``` functions). less.php + will pass the parser object (class ```Less_Parser```), the path to the parsed .less file ("/some/path/to/file.less") and + an identifier that will change every time the .less file is modified. The ```get``` callback must return the ruleset + (an array with ```Less_Tree``` objects) provided as fourth parameter of the ```set``` callback.
