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!

"""A collection of modules for iterating through different kinds of

tree, generating tokens identical to those produced by the tokenizer

To create a tree walker for a new type of tree, you need to do

implement a tree walker object (called TreeWalker by convention) that
|

implements a 'serialize' method taking a tree as sole argument and

returning an iterator generating tokens.
