      Parameters
      ----------
      eups_version
          The EUPS version string (as opposed to tag). This comes from the
          ``__version__`` attribute of individual modules and is only set for
          single package documentation builds that use the
          `build_package_configs` configuration entrypoint.
  
      Notes
      -----
      The variables are:
  
      ``release_eups_tag``
          Always ``current``.
      ``version``, ``release``
          Equal to ``eups_version``.
      ``release_git_ref``
          Always ``master``.
      ``scipipe_conda_ref``
          Always ``master``.
      ``newinstall_ref``
          Always ``master``.
      ``pipelines_demo_ref``
          Always ``master``.
