# plexpy_enable (bool):     Set to NO by default.
#                       Set it to YES to enable it.
# plexpy_user:  The user account PlexPy daemon runs as what
#                       you want it to be. It uses 'plexpy' user by
#                       default. Do not sets it as empty or it will run
#                       as root.
# plexpy_dir:       Directory where PlexPy lives.
#                       Default: /usr/local/plexpy
# plexpy_chdir:  Change to this directory before running PlexPy.
#     Default is same as plexpy_dir.
# plexpy_pid:  The name of the pidfile to create.
#     Default is plexpy.pid in plexpy_dir.
