I don't know where they are on the net, but I'll be happy to email them to
you. Or, if you have a Red Hat distribution, you might be able to find them
there.

Maybe I missed something in Joerg's analysis, or maybe I forgot to summarize
the Knuth/TeX license. Essentially, it is this: "Use this software for
anything that you wish, but don't modify it and call it TeX". In other
words, Knuth retains control over TeX, but has no objection to anyone taking
that code & starting another project with it -- he just doesn't want any
confusion over what is TeX. I agree that it is a non-trivial matter, and
that we need to respect everyone's rights, so if I have misunderstood
something, please set me straight. Otherwise, I think we really can simply
apply the Apache license to that work. The credits are simple courtesy. I
just think it is better to start with something that works, even if
incomplete, and have contributors add to it to make it complete, than to try
to mess with the other licenses.
