File system based database that uses Python pickles for Python 3

 Like shelve, a PickleShareDB object acts like a normal dictionary. Unlike
 shelve, many processes can access the database simultaneously. Changing a
 value in database is immediately visible to other processes accessing the
 same database.
 .
 Concurrency is possible because the values are stored in separate files.
 Hence the "database" is a directory where all files are governed by
 PickleShare.
 .
 This package installs the library for Python 3.
