Today I have released CL-EMB. It's a kind of combination of LSP (LispServer Pages) and HTML-TEMPLATE. You can embed Common Lisp (hence the name) into textfiles. Between <% and %> can be Common Lisp or special template tags like @if, @repeat, @loop, ...
It's in an early stage. Version 0.0.1. Needs a real documentation and lots of examples.
