#
# Read lines from `stdin` and submit them to the cogserver for
# processing. Each line is quoted and then wrapped by the <observe-cmd>
# before being sent. For example, if the line is "some text\n", and
# <observe-cmd> is "do-thing", then the CogServer will receive
#
# (do-thing "some test")\n
#
# Note that the trailing newline is chopped off the end of the line,
# and "do-thing" is assumed to be a scheme function that the cogserver
# is able to execute.
#
# For pair counting, ARGV[2] is "observe-text" or "observe-window"
# For MST disjunct counting, ARGV[2] is "observe-mst"
# For planar MST disjunct counting, ARGV[2] is "observe-mpg"
#
# Example usage:
# cat file | ./submit-plain.pl localhost 17001 "observe-window 24"
#
# This script will wait (hang) until the cogserver is idle enough
# to be able to respond. That is, it waits until the cogserver has
# (mostly) finished running the command.
