=head1 DESCRIPTION
field called "name" to be considered a foreign key, so you could
include it in the "skip" option, and all fields called "name" will be
excluded from natural joins. A more efficient method, however, might
-be to simply deduce the foriegn keys from primary keys to other fields
+be to simply deduce the foreign keys from primary keys to other fields
named the same in other tables. Use the "natural-join-pk" option
-to acheive this.
+to achieve this.
If the schema defines foreign keys, then the graph produced will be
directed showing the direction of the relationship. If the foreign
keys are intuited via natural joins, the graph will be undirected.
