Lua web stuff

["Eric Tetz" <erictetz@...>]

I need to write a web interface to a database, and was considering Lua ('cause it's fun ^_^).  A  quick Google turns up Kepler, which judging by the website alone seems to be fairly mature. Are there any other mature ones? How robust/complete/usable are these compared to something like PHP?  

It's hard to me to evaluate any of them, because I'm not super hip on the current state of web application development and don't my expected pain threshold should be. The last web development I did was CGI in C many years ago; I would imagine frameworks have gotten fairly sophisticated since then.

Thanks in advance for any tips.

Cheers,
Eric
