This version of SickBeard uses both TVDB and TVRage to search and gather it's series data from allowing you to now have access to and download shows that you couldn't before because of being locked into only what TheTVDB had to offer. Also this edition is based off the code we used in our XEM editon so it does come with scene numbering support as well as all the other features our XEM edition has to offer. Please before using this with your existing database (sickbeard.db) please make a backup copy of it and delete any other database files such as cache.db and failed.db if present, we HIGHLY recommend starting out with no database files at all to make this a fresh start but the choice is at your own risk! Enjoy!

"""Generic configuration system using unrepr.
|
|
|
|
Configuration data may be supplied as a Python dictionary, as a filename,
|
|
or as an open file object. When you supply a filename or file, Python's
|
|
builtin ConfigParser is used (with some extensions).
|
|
|
|
Namespaces
|
|
----------
|
|
|
|
Configuration keys are separated into namespaces by the first "." in the key.
|
|
|
|
The only key that cannot exist in a namespace is the "environment" entry.
|
|
This special entry 'imports' other config entries from a template stored in
|
|
the Config.environments dict.
|
|
|
|
You can define your own namespaces to be called when new config is merged
|
|
by adding a named handler to Config.namespaces. The name can be any string,
|
|
and the handler must be either a callable or a context manager.

namespace, and will be passed two arguments: the config key (with the
|

namespace removed) and the config value.
|

Namespace handlers may be any Python callable; they may also be

Python 2.5-style 'context managers', in which case their __enter__
