I was making some research today on some possible GIS frameworks
that would use Lua as an extension language, and I randomly came across
this project: TerraME 
I will just quote the wiki page:
"TerraME is a programming environment for spatial dynamical modelling. It
supports cellular automata, agent-based models, and network models
running in 2D cell spaces. TerraME provides an interface to TerraLib
geographical database, allowing models direct access to geospatial data.
Its modelling language has in-built functions that makes it easier to
develop multi-scale and multi-paradigm models for environmental
I believe it uses Lua 5.1.4. Yay.
Just wanted to share this information. Hopefully, it might be relevant to someone. Also, maybe Sir Marbux can update the page "Where is Lua Used ?"  with that ?
i don't know if this would qualify in terms of popularity, but my Podball project [https://sourceforge.net/projects/podball/] uses Lua as well. Any chance it could make it into the list too? (probably best classified as game engine or game)
> If I may, I have another addition to that list as well :
> Agen is a nice frameworks for games, using Lua as a programming language.
> It can be used to make commercial games for iOS, Android, Windows and Linux.

Thanks. Page is now updated.
