Hi Lorenzo,

good to hear you are working on it and that it's working in some way.
There's no need to send me the vapi files unless you feel you don't
have enough time to complete the full generation integration to
makefiles (in that case I would just distribute the vapi's and the
build integration would be done later). Also if you want some more
time I can make the release a bit later - I just want to make it
around the gnome 3 release time.

I was wondering if we need the bindings directory at all - are some of
the metadata files needed or only gir files are used for the
generation? If so then it would be maybe enough to extend the
makefiles in champlain and champlain-gtk directories and move the vala
demo under demos.

Also if you generate the vapi's in the makefiles, there should be a
configure option for enabling/disabling vapi generation. The
generation should actually be needed only when new release is made and
not during ordinary build. But don't worry about such details much - I
can adjust the makefiles myself once I see how the generation works.

Thanks for your work!

Jiri
