Ah. Well, I must've overlooked that example. I don't use CVS, so any
examples of how to use Subversion by comparing it to using CVS were
not relevant to me.

Why do you want to do it this way? Why don't you just import all the
files in the tgz archive into Subversion? That would be the normal
way to use it...

I don't know what you mean. You should show us the exact command you
execute, the exact output (or behavior) you get, and tell us how this
differs from the output (or behavior) you expect.
