BSD Vacation v2 is a rewrite of the 'vacation' program that has come with Sendmail (and thus *BSD) since about 1983. This version has been almost completely rewritten in an attempt to get it closer to RFC-2822 compliance than any previous version. It properly responds to the correct recipients, as per the RFC, and it correctly handles multi-line headers. The command-line interface is compatible with previous versions, and most recent add-on features from the various *BSD projects have been implemented, such as support for preloading the recent recipients database.
CVSToys is a collection of companion tools for the Concurrent Versions System, better known as CVS. It currently contains FreshCVS, which performs actions in response to a commit. Actions include notification by various methods, updating a working copy, and rsync'ing to backup. Another key feature of FreshCVS notifications is that you receive one per commit, not one for each directory of the commit as loginfo-triggered scripts are prone to do. FreshCVS is extensible with Python, and notifications may be published by a Perspective Broker network service, allowing 3rd party clients to listen in.
Ebola is used as a bridge between AV engines (e.g., Sophos) and scanning scripts (e.g., Inflex and AMaViS) to provide much-improved performance by handling file scanning requests on behalf of the scripts while keeping a SINGLE session of the AV engine open, rather than restarting one each time.
