# Simple utility to trigger a Verify job on a bunch of hosts.

# CAVEAT:  no error checking; if any argument isn't a valid
# host, it will be silently ignored.  If there are no command
# line arguments, silently succeed.

# For simplicity, we want to do nothing if there are no hosts named
# on the command line.  That makes it easy to do stuff like this:
#     dut-status -b $BOARD -p bvt -n | xargs reverify_hosts
#
# By doing nothing, we get more useful behavior if all the DUTs selected
# by `dut-status` are actually working.
#
# Note that we have to specifically test for an empty host list: I
# _think_ (but I don't know) that the AFE calls operate on all the
# hosts if there are no arguments given.  I do know for certain that
# with hostnames=[], the call takes longer than I was willing to
# wait.
