.Sh DESCRIPTION
.Nm
is a utility distributed with FreeTDS.
.Nm
will move table data from one server to another without the need for
intermediate files.
.Nm
is much faster and more efficient than is freebcp out/in.

.Nm
makes use of the db-lib bcp API built into FreeTDS. This API is also
available to application developers.
.Pp
.Nm
