diffmon 20020222-9.2 (amd64 binary) in ubuntu noble

 This tool is run by a nightly cron job, and takes a `diff' of specified system
 configuration files and emails them to a specified email address. Options to
 diff can be specified. This is useful in friendly environments where there are
 multiple sysadmins working on configuration files/setups and everyone's changes
 are reported. CVS is a better answer, but the most of people don't want to have
 the hassle of putting system files in a repository.
