Conary is a distributed software management system for Linux distributions. It replaces traditional package management solutions (such as RPM and dpkg) with one designed to enable loose collaboration across the Internet. It enables sets of distributed and loosely connected repositories to define the components which are installed on a Linux system. Rather than having a full distribution come from a single vendor, it allows administrators and developers to branch a distribution, keeping the pieces which fit their environment while grabbing components from other repositories across the Internet.
checkroot is an openSUSE equivalent of debsums. It enables retrieval of fingerprint updates online, allowing trusted verification of a root filesystem. This prevents a cracker from hiding his traces from "rpm --verify -a". If the verification fails, checkroot can download the package header containing the md5sums online. Alternatively, all md5sums can be fetched online (if you mistrust some of the fingerprints/private keys the locally stored md5sums are signed with).
Mouf is a special kind of PHP framework. It combines an Inversion of control (IOC) framework and a component download system in a nice Web-based user interface. The goal of Mouf is to help you use and re-use components. By itself, it does not provide anything useful, but it will help you download and install libraries of components, and bind those components together. You will get better and cleaner code using Mouf. Mouf features more than 100 packages providing various ready-to-use components of a Web application, ranging from an MVC framework to an ORM layer, logging, form generation, image manipulation, Drupal integration, authentication, etc.
Sincerity is a tool for installing and bootstrapping software stacks on top of the JVM. It makes these otherwise tedious tasks easy, simple, and fun. Your Sincerity containers are straightforward development playgrounds. Simply create a new container when you want to try out a new approach. Delete the directory when done, and it's as if nothing ever happened. Sincerity's growing ecology of plugins makes it especially easy to add powerful features to your product, such as centralized logging and robust daemons with surprisingly minimal fuss.
