DESCRIPTION
       This script will create a picture of your schema.  Only the database
       driver argument (for SQL::Translator) is required.  If no output file
       name is given, then image will be printed to STDOUT, so you should
       redirect the output into a file.

       The default action is to assume the presence of foreign key
       relationships defined via "REFERENCES" or "FOREIGN KEY" constraints on
       the tables.  If you are parsing the schema of a file that does not have
       these, you will find the natural join options helpful.  With natural
       joins, like-named fields will be considered foreign keys.  This can
       prove too permissive, however, as you probably don't want a 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 named
       the same in other tables.  Use the "natural-join-pk" option to achieve
       this.
