Tom,

With the addition of transaction support, database files now exist in
the context of a database environment.  This means that you
can't just (willy-nilly) copy wordlist.db from one place to
another.  A simple copy doesn't preserve the logfiles and (if
the database is being written during the copy) can produce a b0rked
databbase.

bogoutil dump/load _can_ be used to create a new, compact environment
from an old one.  However the extra files need to be dealt with, which
is exactly what bf_compact takes care of.  bf_compact performs the
proper operations in the proper order to ensure the database environment
is whole and complete when the script finishes.
