In the RichFaces Bootstap Sandbox project we are currently using the wro4j project to compile our LESS code into CSS during our maven build.  An alternative approach has recently become available as the less4j project is now able to compile the Bootstrap project.

Code Lerum recently reported via twitter that he noticed significant speed improvements in his project build by switching from wro4j to less4j.  I suggest we look to see if this approach is sufficiently robust for the RichFaces Bootstrap Sandbox project, and consider it for our LESS plans for Richfaces 5.

Thoughts?
