# Use "Extensions > Export all" in the desired channel and category,
# to export all station entries at once. Currently just export PLS,
# which in turn references other .pls file).  Luckily most players
# can cover up for this horrid misdesign.
#
# This is a workaround until the main GUI supports selecting multiple
# rows at once, and the action.* module has been overhauled to export
# a bit more deterministically.
