"the main goal of the workshop is to allow the Lua community to get
together and meet in person and talk about the Lua language, its uses,
and its implementation.... We shall have a plenary talk by Roberto
Ierusalimschy (Lua's chief architect) and several contributed talks....
If you'd like to speak at the workshop, please send a tentative title
and a short abstract to the organizers."
If you think it would be useful for Wikimedia to make an appearance, go
ahead and submit an abstract or suggest someone to go.
