makeSonosShareLinks.sh should have more error reporting, particular to examine the dirs where links are created, and report on links that don't go to a valid place.

This reference shows various ways to do it, but we need to find ones that work with the very limited QNAP NAS system: http://stackoverflow.com/questions/5767062/how-to-check-if-symlink-exists

Another option is to create a general "test" script on the NAS, that checks to see that the share list in SonosShareList.txt exists, and to report all broken links.

@cdmiller We need to resolve this:
Lib checker and fix_lib.rb rely on SonosConfig.yml for directory names.
Gong files there are in a VMC Alarms directory
gongs_dir: "/Volumes/Dhara/SonosLibrary/Sonos Customizations/VMC Alarms"

whereas the make links shell script is specifying a VMC gong directory

AUDIOBASE='/share/HDA_DATA/SonosLibrary' # Source: base directory of audio library

common and custom and important file and folder paths put here

GONG_FOR_SONOS_ALARM=$AUDIOBASE/'Sonos Customizations/VMC gong/gong_sonos_alarm.mp3"
