CfStatic now supports compiling of LESS CSS
If you've not heard of LESS CSS, head over to http://lesscss.org/ and fall to your knees in humble awe (and get all coder giddy).
In CfStatic, simply create .less files with LESS css in them in exactly the same way you create .css files for CfStatic. CfStatic will take your .less files and compile them as css, saving the output to
yourfile.less.css. It will then minify that compiled css file in accordance with the rules you configure.
