Usage: $(basename "$0") [flag]... [target] [pattern]...

Run one or more Tast tests against a Chrome OS test device using
binaries from an autotest_server_package.tar.bz2 archive.

Additional flags for "tast run" may be supplied, most notably:
  -keyfile=PATH     passwordless private SSH key to use
  -resultsdir=PATH  directory where results will be written

Positional arguments:
  target   DUT as "host", "host:port", or "user@host:port"
  pattern  test pattern as a test name (e.g. "ui.ChromeLogin"),
           wildcard (e.g. "power.*"), or parentheses-surrounded
           test attribute expression (e.g. "(bvt && chrome)")
EOF
  exit 1

# Try to find the testing SSH key. If -keyfile was passed as a positional
# argument, it will override the flag added here.
