# Script to control upmpdcli from the command line. Needs aux xml files to
# define the commands. Very few of this is specific upmpdcli-specific
# elements are noted by comments.
#
# The XML file names are like Servicename-ActionName The servicename part
# is only used to compute the service control url (which is specific to
# upmpdcli). The OpenHome service names themselves are special because
# upmpdcli prefixes them with OH (e.g. OHVolume instead of volume). So the
# whole service control url computation (and only it) would need changing
# for another renderer.
#
# LIMITATIONS:
# - does not work for parameter values containing whitespace
