This is a program which imports "exported" Citadel databases. It will be used

This is a program which imports "exported" Citadel databases.  It will be used
primarily for Citadel5->Citadel6 migration, and perhaps to change database
managers on an existing system.  (There is an "export5" utility for Citadel 5,
and this import utility works on Citadel 6.  Therefore, the migration works,
but until an import utility is written for Citadel 6, the changing of
database managers isn't possible yet.  That probably won't be a big deal,
though, because after I discovered that the inflated message base size problem
was due to the netproc bug rather than poor GDBM implementation, we'll probably
stick with GDBM.  Indeed, GDBM is _exceptionally_ efficient with disk!
