This is a project for Kids on Computers to give access to Khan Academy offline

There are several tools available here:

http://www.khanacademy.org/downloads

However, the closest existing tool is designed for running a local instance of the website in
Windows (using google app engine) and so this version of the tool took the python scripts from 
http://code.google.com/p/khanacademy/downloads/detail?name=KhanAcademy-1482.zip&can=2&q= and have been adapting them to

a) work with other video formats (mp4, ogg) that exist on archive.org
b) allow for updating of the canonical list of available videos based on the archive.org rss free
c) provide a command-line interface for interacting with this tool
d) use json output from archive.org to build the information instead of a hard-coded mapping that can get out of date

TODO:

* SMS if there are updates available (twilio)
* Create our own 'readable_id' in the mappings for new additions based on title.tolower() s/ /_
* integrate youTube downloading not as an exception handling case
* better handling for keyboard interupt while downloading (incomplete file downloads)
