There is a good implimentation of this in AutoIT v3. I would love to have
the same functionality in wxLua.

Ah, ok. I saw bin2c.lua in the 'utils' directory i will look into how you
did that.

2) Embedding dlls is not so easy I think. I have toyed with the idea

Yeah I am really looking for something really simplistic, that just appends
to the executable then extract to the specified location.

You may want to do a web search for how to embed dlls in C++ and how

Ok. Will do and I will let you know what I find out.
