It is easier than that. There a 2 backward compatibility
layers in the C code that are not really needed. If you
just focus on Itcl 3.X, it will be a lot easier. Just
ignore the 1.X and 2.X layers.

Cool.

It works for loading packages off the filesystem.
What does not work is loading packages out of
a .jar file. It would not be all that tricky,
it just needs someone to do it.

The "external resolvers" thing in an internal namespace
API that is only used by Itcl. It would be trivial
to add it to NamespaceCmd.java.
