#    Description:
#      This file is the makefile for a script that synchronizes the
#      music-only portion of a user's iTunes and/or Music library to a
#      locally-mounted, remote file share using rsync.
#
#      The remote file share is typically a NAS volume hosted by
#      a product such as QNAP or Synology, accessible by Sonos.
#
