Oh, great! I'll build svn as soon as I get back to my computer (this
one has no linux here). I plan on handing more patches as soon as I
learn more about the internals of the Vala compiler.

By the way, is there any lose documentation on how the different
classes interact with each other ? Something like a sketch on the
class diagrams ? If you have anything in paper and is able to scan and
send I can get it digitalized with Dia so we get a basic information
for new developers.
