Ok, this is your direction, but others (like Cython or people that use
pyrex) would like to apply your changes like that. We're just asking
you to choose a tool that would help us too, maybe it's too much? ;-)

You should _NEVER_ touch these .hg (or .git) directly, and copying
them with Finder will work because you should drag the base folder,
not its contents (makes sense to me).

As for dealing with files moving around, at least GIT does a great job
there, it just works, but I think that HG is also good there, Robert
and others can comment on that.

If you change things, these changes need to be stored, so yes, it
grows. But since changes are kept packed, they don't loose too much
space. The whole Linux kernel repository with all its history is not
bigger than 200mb (last kernel's tar.gz is around 50mb).

You can find some numbers http://git.or.cz/gitwiki/GitBenchmarks
(which also shows Hg is not as slow as I thought).

Great!
