"""OK. This is a sample Scribus database connection with Python HOWTO.

DESCRIPTION:
I've got questions about DB and Scribus in my personal mailbox 3-4
times in a month. So this is an common answer for asking people.

Even through I'm an Oracle user/developer I choose MySQL for this
example, because of its presence in the Linux distributions and
hosting availability too.
But the DB server doesn't matter due the PEP 249 - standard DB interface
(http://www.python.org/peps/pep-0249.html).
There are various modules for database accessing:
http://www.python.org/topics/database/modules.html

Anyway - this script provides connection to the database server by the
specified values in the hostname, dbname, username, and password variables.
Then it checks the system for table names in the specified databases
and it displays it in the new document finally. Easy and understandable.
