Ketarin on the other hand does not keep the software on a specific computer system up to date. The difference is that Ketarin checks if a software installer has been updated on a specified location and downloads the new installer to a location defined by the user of the software.

The main purpose of the software is therefor similar to the concept of those automatic updaters but with the difference that it only downloads the new program versions so that they can be distributed to a network of computers. It can naturally be used to install the new version on the computer that Ketarin is running as well.

Ketarin can monitor software installers in three different ways.

• Monitoring URLs for changes
• Monitoring and using the FileHippo service
• Using placeholders to watch webpages for changes

The software developers have created a short documentation that gives examples for all three ways of monitoring software installers.

Applications that are monitored can be grouped into categories. There is also the possibility to run commands after downloading an updated software installer and to import or export applications to XML files.

The software program is Open Source and portable. Some would say it is not as it requires the Microsoft .net Framework 2.0.
