Searching something else, I found some projects using Lua but that,
for some reason, are not listed in the user project list
<http://www.lua.org/uses.html>, and rarely or never mentioned in this
discussion list.
- FreePOPs was mentioned by the creator (Enrico Tassi?) in this list,
it can be found at http://www.FreePOPs.org
It allows to access webmail content through a local POP3 server, Lua
being used to parse HTML pages (I oversimplify description...).
- Celestia, the well known "free real-time space simulation that lets
you experience our universe in three dimensions."
<http://celestia.h-schmidt.net/>. It can be scripted in Lua since the
1.3.1 version (current version is 1.3.2).

- MUSHclient is a commercial MUD client for Windows, scriptable in
Lua, amonst other scripting languages.

There are probably more, but that's all I found today...
May I suggest to authors, if they (still) read this list, to
officially mention your software (or Lua scripting extension) to Luiz
for inclusion in the above page?
