usage_string = """Orchestrator usage examples:

The orchestrator runs tests and updates multiple devices.

$ %s *
Run all tests on all devices in current state.

$ %s * -v version[:end_version]
Run benchmarks on single or range of versions. The versions can have the
following format:

  "-v 42" Last version that starts with 42.
  "-v 42-" First version that starts with 42.
  "-v installed" Currently installed version.
  "-v latest" Latest version.

You can also specify ranges of versions by separating the first and last version
to run with a colon. If nothing is specified on either side, the first or last
version is implied.

  "-v 42-:42" Every version that starts with 42.
  "-v installed:" All versions since the currently installed one.
  "-v :42" All versions until the last one that starts with 42..

The wildcard * can be replaced with any glob such as:

$ %s nexus5/*
Run all tests on nexus5

$ %s */tap
Run tap benchmark on all devices

Whereas the names of benchmarks are put together in the following format:
  dut_name/subject_name/benchmark_name
