Arvados CLI tools are written in Ruby and Python.  To use the @arv@ command, you can either install the @arvados-cli@ gem via RubyGems or build and install the package from source.  The @arv@ command also relies on other Arvados tools.  To get those, install the @arvados-python-client@ and @arvados-cwl-runner@ packages, either from PyPI or source.
