Hi Kyle,

The transfer manager was designed as a very general method of downloading data 
to a temporary location in a Galaxy-independent-but-manageable fashion.  To 
make it more useful, it's designed to be used with deferred jobs.  The idea is 
that you write a deferred job plugin that can be told when to initiate a task 
(like adding things to the transfer manager), create deferred jobs that depend 
on those transfers, and then take certain actions that you specify once those 
transfers have completed.  There's no documentation, but if you have a look at 
the existing plugins in lib/galaxy/jobs/deferred, that should give you an idea 
of how it works.
