Thanks for the link, it is the first time I have seen your work - I
somehow missed it on my numerous searches through the net looking for
bread crumbs.

I initially tried auto-translation to Java - spurred on by the type
info, then retreated back to a similar strategy to yours of loading in
tweaked versions into a current Smalltalk. I managed to get some of
the tests to partially run. Unfortunately the tests aren't self
checking, and seem to require diff'ing against the results of a known
good run.

Just like you my efforts faltered while working with the original
code; primarily due to its large size, generality, lack of
documentation and mysterious naming. It's also unclear of what was
left to do, and open bugs, at the time the original development
ceased.

Your work seems to be a lot more organized than my importing efforts,
and I'm impressed that you managed to get some of the missing classes
from the XOC people.

I am dipping into the original source for my Abora app, but the best
headway to understanding Udanax-Gold seems to be a paper on a
simplified form of the Ent, and the first couple of chapters of the
Xanadu Information Architecture docs. I think both are referenced from
the Abora readme files.

Cheers
