HTML templating languages can be lovely, but it's often a pain to rewrite raw HTML into their particular syntax. Metamorphic lets you do 99% of the work with a simple command-line tool.

npm install metamorphic

Metamorphic was built by Michael Mokrysz at the very end of 2012, and is openly licensed under two-clause BSD.
I'd love contributions (whether code refactoring, new templating languages, or fixes) - fork the repo on Github and get hacking.
