Converting LESS to CSS

Node.js compilers

For advanced users, this plugin allows you to define and manage LESS "packages" or "bundles" using JSON, Lo-dash(underscore) templates (e.g. <%= bootstrap.less %>), and node-glob / minimatch (e.g. '../src/**/*.less"). assemble-less also has a number of options including minifying CSS
• RECESS: Twitter's code quality tool for CSS built on top of LESS. RECESS has options for compiling LESS to CSS, as well as linting, formatting and minifying CSS.
• autoless: A LESS files watcher, with dependency tracking (changes to imported files cause other files to be updated too) and growl notifications.
