# this script tests the keepalive functionaly
# it is really only meant to be run by the developers, but it's a start
#  on the regression tests.
# It's likely this script would need extensive customization before
#  it's able to be used.
# If you don't like the code, either fix it or shush.
# NOTE: Needs userland programs: awk, grep, md5sum, stat, socket, wc
