    dvm is a shell function, and must be sourced before it can be used.
    Add the following command to your bash profile:
        [ -f #{opt_prefix}/dvm.sh ] && . #{opt_prefix}/dvm.sh
    EOS
  end

  test do
    output = shell_output("bash -c 'source #{prefix}/dvm.sh && dvm --version'")
    assert_match "Docker Version Manager version #{version}", output
  end
