-=item B<loadbibs> --stage_file foo.mrc
-
-Takes a load of bibs from a binary marc file and loads them into mig staging table
-of bibio_record_entry.
-
-Takes these optional arguments:
-
---append
-
-When used it does not drop the staging table and instead adds onto it.
-
---source
-
-Sets an x_source value on the staging table to the one supplied instead of the
-default of none.
-
---xml
-
-By default the program assumes a USMARC file. This flag will identify it as
-a MARCXML file instead.
