If you liked the Windows version, you're going to be even more amazed
when the Linux version is ready. :) I just hope that someone else gets
impressed and offers me a job... (I'm going to graduate this semester
and I realized I don't want to work as a civil engineer) :)

I don't believe we need to worry about LDraw because TLG don't see
adults as a good market and it's too difficult for a kid to use it.
Besides that, they can complain about the parts but not about the
program itself (you can say that it's just a generic drawing program).
And I agree that if they think they're loosing money they won't think
twice before going after us.

That's a bad habit, it doesn't take much time to just put all the
source files in a zip package and save it in a floppy. You'll need the
original files anyway when a user sends a bug report.

I'd say that looking at other successful projects is the best way to
learn, I've learned a lot just by looking at how other programs were
done. I've examined the Doom source code and it gave me a lot of ideas
on how to write cross platform code.

I couldn't agree more, the most important step in development is the
design. If you don't plan how things are going to be done before you
start writing, you'll have a lot of trouble later. I've learned that the
hard way and had to rewrite LeoCAD a couple of times.

That's what I just did, I created a separate class (only with ANSI C
calls) to handle almost everything and the rest of the code would just
call members like "OnMouseMove" from this class.
