# Lets the status panel start Dante Virtual Soundcard's audio engine, which needs admin rights:
#  1. {{DVS_HELPER}} - an admin-owned script that does exactly what
#     pressing Start in DVS does (sets wantToRun = 1 and restarts the DVS service), nothing else.
#  2. /etc/sudoers.d/status-panel - lets the logged-in user run ONLY that script as admin,
#     without a password. It is checked with visudo before it is put in place.
# Undo on a Mac: rm {{DVS_HELPER}} /etc/sudoers.d/status-panel
