=item Create

Create any missing entries. This is only expected to be run during initial
build of the table. Once summation occurs, this becomes redundant.

=item Update

Update table release_summary.

=item Rebuild

For a give distribution and version, rebuild all related entries within
the release_summary table.

=item Fix

For all distributions and versions, rebuild all related entries within
the release_summary table.
