| This is the <a href="http://www.lua.org/">Lua</a> interpreter, compiled from C to JavaScript using <a href="http://emscripten.org">Emscripten</a>, |
| running in your browser (without any plugins). |

| <p> |
| <ul> |
| <li>Most stuff should work, please report bugs if you find them!</li> |
| <li>Note that this is an unoptimized build (see <a href="http://code.google.com/p/emscripten/issues/detail?id=8">issue 8</a>)</li> |
| <li>The editor is <a href="https://mozillalabs.com/skywriter/">Skywriter</a>. Would be cool if someone made a syntax highlighting plugin for Lua... |
