That is my understanding as well.

Actually, TortoiseHg is a derived work of multiple other projects,
as parts of other GPL'ed projects (not just Mercurial) have been
taken into TortoiseHg.

But Mercurial is surely the most important part here, as
TortoiseHg is using it's python API directly, which falls
under the linking restrictions of Mercurial's license.

But that does not answer my question. Why does Wagner say
BSD is needed for TortoiseHg translation? I don't get that
part...
