fs.appdirfs
===========
A collection of filesystems that map to application specific locations.
These classes abstract away the different requirements for user data across platforms,
which vary in their conventions. They are all subclasses of :class:`fs.osfs.OSFS`,
all that differs from `OSFS` is the constructor which detects the appropriate
location given the name of the application, author name and other parameters.
Uses `appdirs` (https://github.com/ActiveState/appdirs), written by Trent Mick and Sridhar Ratnakumar <trentm at gmail com; github at srid name>
