        <para>
            Lists all refs available on the host.  If specified, PREFIX assigns the refspec prefix; default
            prefix is null, which lists all refs. This command can also be used to create or delete refs.

                without this option will strip the specified prefix
                from the output.  Normally, one wants to see the full
                ref, so providing this option ensures the refs are
                printed in full, rather than
                truncated. </para></listitem>

                    Create a ref pointing to the commit EXISTING. NEWREF must not already exist, and EXISTING
                    must be an existing commit. More than one ref can point to the same commit.

                  Enable interactions with refs using the combination of their
                  collection IDs and ref names. When listing refs, this changes
                  the output format to include collection IDs, and enables
                  listing remote mirrored refs.</para>

                  <para>When creating refs, the refspec value passed to the
                  <option>--create</option> option is treated as
                  <literal>COLLECTION-ID:REF-NAME</literal> and a mirrored ref
                  is created. (This is an abuse of the refspec syntax.)</para>

                  <para>When deleting refs, all refs whose collection ID equals
                  PREFIX are deleted.
