Subject: [PATCH] Add a daily script to the periodic framework that reports
 changes to the package database, i.e. any packages that have been added,
 updated or deleted in the past 24 hours. The format is intentionally simple
 and concise.

That information is particularly useful on servers that
are maintained by multiple administrators.  When someone
adds, updates or deletes a package, the others will see
it in the daily periodic output.

This script is disabled by default.
