## usage: fx dart-remote-test
##            [-h|--help] [-d|--device <device>] <target-pattern>
##
## Attempts to run a test targeting a remote fuchsia device.
##
## This command requires Topaz in order to run. An example would be to run
## this command against //topaz/example/test/driver_mod_example/* to run
## all dart_remote_test targets.
##
## Arguments:
##   -h|--help    Print out this message.
##   -d|--device  Fuchsia link-local name of the device. If not
##                specified, will connect to the only available
##                device on the link-local network.
