Just letting people know about a project of mine - a new templating language; Renshi. See http://github.com/biv/renshi/tree/master . It's also available via gem installation through rubyforge.
It was originally modelled on Python's Genshi, although it turned out rather differently. It'd be useful for dev.s who work with HTML handed to them, or who find ERB a bit onerous - e.g. $foo is the same as <%= foo %>.
It's early days yet with it, but it's functional.
The README at github should explain everything.
