I want to use part of front end template and use part of back end template.
so catch the token definition rended!
open {{
close }}

I want to chang to
open: '<%=',
close: '%>'

or use raw block to render?

It'll be a useful feature.

Most (if not all) lexical parsing is located at src/tokenizer.js, it should be easy to provide options to re-define the syntax for outputs and tags. PR is wellcome, I can help make it running.
