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 foreign keys from primary keys to other fields named the same in other tables.  Use the
       "natural-join-pk" option to achieve this.
