Q:

Mustache template library?

What are some use cases for mustache? 
I just discovered it today but I can't seem to understand how is it different from just creating regular template files in your framework (cakePHP, django, etc..) or just having an html + php file.

A:

Mustache allows almost no intelligence in the view--separation of concerns is its usecase.
It is another template engine/library, the only (real) difference is in its syntax and philosophy.
