LESS CSS parser (http://github.com/cloudhead/less.js) installed with Node.js on the server your site will run on. The command for this parser is in the extension.driver.php file. If you choose another LESS parser, please change the command.
As this extension uses the lessc executable to do the conversion you'll need to make sure PHP has access to the lessc executable or its alias. If the extension isn't working for your out-of-the-box, try setting the $less_exec variable at the top of extension.driver.php to the full path to the lessc executable. It'll be something like /usr/local/bin/lessc, you should be able to find out by typing which lessc into the shell on your server.

Links to
.lessfiles in your templates will now be automatically converted to CSS.
To use the Sass Helper you simply need to point your CSS includes to your .less instead of .css. The extension will automatically find them and generate a .css file in the same directory. For example, this:
<link href="{$workspace}/assets/less/screen.less" media="screen, projection" rel="stylesheet" type="text/css" />
Will be output as:
<link href="http://domain.com/workspace/assets/css/screen.css?mod-1248022788" media="screen, projection" rel="stylesheet" type="text/css" />
