Less works well if you're using an architecture that will run node.js, since the recommended way generally seems to be: "change code in .less files, process with some node based javascript processor". Don't misunderstand - It's not impossible to use less with other non-node.js based systems, but it is a massive PITA. There's a handy gem "less-rails-bootstrap" which wraps twitters bootstrap files and integrates with the Rails asset pipeline, but again, you should avoid this if you're not running on an up-to-date Intel system, since it has a dependency on "therubyracer" gem (which is V8 for ruby). I have been using SimpLESS a little bit in the recent past, but it does choke on some of the bootstrap less files, and I haven't had the time to fork and rebuild it with a more up to date less library. I think if I was coming to bootstrap now rather than a few weeks ago, I'd have chosen the sassified version rather than less, but fortunately I have an intel system to abuse, so all is not completely lost.
