The Source Ruckus Packager (SRP) is a lightweight, yet fully-featured package manager. The target audience for this packager is not the big-time distribution developers, but a single user rolling his or her own at home (or in a small office). This utility is part of the Source Ruckus project.
debcheckroot is a tool that retrieves file checksums online or from read only media. It provides trusted verification of your root file system at least as far as you can trust your Internet connection or your verification medium (DVD, BD, etc.). Unlike debsums, it doesn't rely on locally stored md5sums which can be modified by an attacker along with the files themselves. It also provides cleaner and better structured output, and can spot files added to your system by someone else.
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.
dput-webdav is a "dput" upload method plugin with extended WebDAV support. It was written specifically with Artifactory and Bintray in mind. It tries to be compatible with the "http" plugin, but offers additional features: login credentials can include the password, "incoming" can be a full URL (optionally containing dynamic package metadata, and supporting HTTPS), and distributions can be mapped to repository names.
ivepkg is a package manager with a focus on homebuilt distributions like Linux From Scratch. Therefore, ivepkg has no repository or network abilities, but is specialized on installing tarballs to a system. Its key features are an easy-to-use database (sqlite3) and a sha1 checksum of every installed file. These make it possible to know which files have been altered (for example, by a malicious attack).
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.
