Thanks for the port Giorgio!
I just recently bought a Glo and I am very interested in this alternative viewer. (Especially landscape mode looks promising because I have a lot of powerpoint slides in PDF format for my studies.)
I am currently trying to setup development for the port (forked it on github) but I didn't get it to compile with cygwin. Trying with a Virtualbox now.
I haven't done C in a very long time, and no experience with Lua. But I'll see what I can do to improve the port.
