I dont like svn:externals either. Probably it's not necessary to keep
them up to date. How about vote for whether to update when discussing
the next milestone build. I incline to grab the src code so that we
won't heavily depends on the script.

yes, I think it is the consistent with Nathan's "more natural fit into
the classlib module structure"

good point. we'd better run these tests on Harmony.
