I knew that, as it is the format used for .reg files.
But it is very verbose and not practical.

Well, an XML parser like Expat is about the same size than the Lua parser,
but it can't be used for scripting... And XML is a chore to code by hand.
OTOH, it is quite standard.

That's what I meant by "you must handle these by hand". Either that, or
creating one section by user.

Been there, done that. Some interesting solutions, but I still prefer to use
Lua...
