.SH CONFORMING TO
The TokuDB embedded database provides a subset of the functionality of
the Berkeley DB.  Programs that work with TokuDB probably work with
with most versions of Berkeley DB with only recompilation or
relinking.  The database files are incompatible, however, so to
convert from one library to the other you would need to dump the
database with one library's tool and load it with the other's.
