#
# Try to connect to an Icecast server.
#
# Optionally, specify stream mountpoints to make sure they're
# currently mounted.
#
# To accomplish this, just pass the mountpoints after the hostname
# using a colon after the hostname and a comma to delimit mountpoints.
#
# Example: neptune:/seattletech,/seattletech-56k,/bdean,/drzzzzz
#
# Outputs hostname:<mountpoint> on failures, or prepends an '*' to the
# hostname to indicate an inability to contact the icecast host in
# general.
#
# Example:
#
# neptune:/seattletech (mountpoint is not mounted on server neptune)
# *neptune (icecast server on neptune is not responding)
