AntiVir Update Announcer is a Perl script can be used in middle-sized networks to inform users about updates to the H+BEDV AntiVir software via email. It uses the same information file as the original Internet update program. It alleviates the need to run the update program periodically just to discover whether any updates are available. Optionally, this script can download the new update file and store it to an SMB share or send it as an attachment to the announcement mail. If used correctly, this will easily increase your network's virus protection.
The aim of the PicoForge project (previously known as PicoLibre) is to provide a set of high level libre software applications that are well integrated in order to provide a collaborative "forge". It makes it easy to deploy a collaborative work platform for developing software or hosting other collaborative activities. Having started (as PicoLibre) in an educational context, PicoForge is now a quite generic platform, comparable (but sometimes less advanced) to other *-Forge software platforms. It groups several high-level applications like phpGroupware, Sympa, TWiki, Subversion, and CVS.
