        <para>

            This searches for unreachable objects in the current repository.  If unreachable objects are found, the command delete them to free space.  If the <option>--no-prune</option> option is invoked, the command will just print unreachable objects and recommend deleting them.

                  This option may currently <emphasis>only</emphasis> be used in combination with

                  <option>--delete-commit</option>.  Previous versions of ostree silently accepted

                  the option without that, and ignored it.  However, there are desired use

                  cases for pruning just static deltas (while retaining the commits), and it's

                  likely at some point this option will be supported for use cases outside of just

                  <option>--delete-commit</option>.
