# controlbatch - Run controlchan against a batch file.
#
# Command usage:  controlbatch [feedsite batchfile]
# Defaults are feedsite: controlchan!, batchfile: ${BATCH}/controlchan!
########################################################################
#
# This script will run controlchan against a batch file.  You can use
# it to clear occasional backlogs while running controls from a
# channel, or even skip the channel and run control messages as a file
# feed.
#
########################################################################
#
# If you're doing the channel thing, you might want to put something
# like this in your crontab to do a cleanup in the wee hours:
#
#	00 04 * * *	@prefix@/bin/controlbatch
#
########################################################################
#
# If you would rather skip the channel and just process controls each
# hour in a batch, use this newsfeeds entry instead of the "stock"
# version:
#
# controlchan!\
#	:!*,control,control.*,!control.cancel\
#	:Tf,Wnsm:
#
# And, a crontab entry something like this:
#
#	30 * * * *     @prefix@/bin/controlbatch
