Lua interactive interpreter in browser

[Attila <ejjeliorjarat@...>]

Hello!
I want a similar interpreter as http://www.lua.org/cgi-bin/demo or  
http://wowprogramming.com/utils/weblua on my homepage. Are they available  
for everybody, or they are uniqe, and just the Lua site is allowed to use  
it?

Attila
