# Description: Appends and optionally plays music in MOC
#
# Notes:
# - if selection is available, plays it, else plays the current file or directory
# - appends tracks and exits is MOC is running, else clears playlist and adds tracks
# - to randomize the order of files appended to the playlist, set SHUFFLE=1
# if you add a directory with many files when SHUFFLE=1 is set, it might take a very long time to finish!
#
# Shell: POSIX compliant
