  41 Usage: adb_remote_setup.sh REMOTE_HOST [REMOTE_ADB]
  42
  43 Configures adb on a remote machine to communicate with a device attached to the
  44 local machine. This is useful for installing APKs, running tests, etc while
  45 working remotely.
  46
  47 Arguments:
  48   REMOTE_HOST  hostname of remote machine
  49   REMOTE_ADB   path to adb on the remote machine (you can omit this if adb is in
  50                the remote host's path)
  51 EOF
