Use this option if for instance you have a css file generated in the root on your web server but have your source less/css/map files in a different folder.
So for the option above you might have This is the opposite of the rootpath option, it specifies a path which should be removed from the output paths.
Pre-loading plugins is necessary if you want to add a Pre-processor.
This is not recommended for production, but for development it allows the compiler to produce a single output file which in browsers that support it, use the compiled css but show you the non-compiled less source.

Allows you to add a path to every generated import and url in your css.
