  --branch BRANCH    - Build branch BRANCH instead of the default, which is
                       inferred from the basename of the directory, with
                       "master" as fallback.
  --build-sort-link LINK
                     - Link to use a link target for the 'Build' table header.
                       If empty, do not format the 'Build' table header as
                       link. (Default: empty)
  --descending       - Sorts the entries in descending order
  --output FILE      - Write output to FILE instead of
