It's no trouble at all, I already did it. ;-)

I just realized there's a substantive issue. Note that we could not do
this:
 gtk 1.2  includedir/gtk/foo.h
 gtk 2.0  includedir/gtk-2.0/foo.h
we had to do:
 gtk 1.2  includedir/gtk-1.2/foo.h
 gtk 2.0  includedir/gtk-2.0/foo.h

You can do this:
 orbit1   includedir/orb/foo.h
 orbit2   includedir/orbit/foo.h

but not this:
 orbit2  includedir/orbit/foo.h
 orbit3  includedir/orbit-3.0/orbit/foo.h

you have to do this:
 orbit2  includedir/orbit-2.0/orbit/foo.h
 orbit3  includedir/orbit-3.0/orbit/foo.h
 
so we may as well go ahead and do an orbit-2.0 subdir right away, so
youu don't have to create this confusion during the stable maintenance
cycle. The orb/ to orbit/ strategy is a source-incompatible change that
causes a bunch of problems, so we really don't want to again change
what people have to put in their #include lines.

So I think it's wrong in a very-much-worth-fixing way to have
orbit/foo.h directly under includedir.

OK, I won't install it then.

I'm not sure exactly what you mean, but I think you mean something
that breaks people's current #include lines.

We can't put -Iincluddir/orbit-2.0/orbit in cflags, because that
breaks other things (it ruins the namespacing provided by the "orbit/"
in #include <orbit/foo.h>).

I think we should go with the orbit-1.0/orbit-2.0 scheme, it's what
every other package does, it's proven to work, and the work is already
done.
