When in Red Pill Mode, I saw that the following libraries were available for installation (via the Application Manager):

liblua50
liblua50-dev
liblualib50
liblualib50-dev

Is that all that is needed to develop lua programs on the tablet?

(And no, I have never been in Red Pill Mode, it wasn't me, I deny everything!)

I just noticed that

lua50
lua50-doc

are also available. I install these and give it a try. Is there any way to get these packages bumped up to version 5.1, the most recent implementation of lua?
