podracer info

[Jude DaShiell]

The documentation for podracer should probably have a little more to it 
concerning storage formats for podcasts.  Here's what I've found out so 
far.  Dates in the form yyyy-mm-dd are the first storage level in the 
podcasts directory.  In order to put podcasts into their own podcast 
directory based on feeds as second level directories below the date 
directories the format for the subscriptions file is: url 
/feed-directory-name The (/) before the feed-directory-name makes the feed 
directories go below the date directory names.
