Recently Bill Sebok posted some changes to news to allow the "r"
mail reply command use an optimal path database.  Users of the
"mkpath" program will note that mkpath does not create any dbm
files.  Here is a program to create dbm files for use by Bill
Sebok's changes.  It assumes that the mkpath database is in
the file "/usr/lib/uucp/alpath".
