I have seen that there is a question about gpl and dual licensing, but I know copyleft can behave different depending on the shape of the software.
so here's my question:
I have a package of lua programs.
They use each other. (like libraries)
some are gpl.
Some are completely mine.
Can I dual license the whole thing under gpl (gpl programs) and (my stuff)?
How does this change when the programs that are not my stuff are lgpl?
