What are Facelets?

[Himanshu Gupta]

After searching on Google I found that they are used as a replacement of JSP processor framework. Facelets are efficient and provides good error log.

Is there anything else which I am missing?
Also I want to know that when should be Facelets used and when not.

Thanks for help.
