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.
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.
Admin-packages is a package manager for sources. Among other things, it handles multiple local and remote repositories, user defined tmacro transformations, recursive dependency resolution, installation logging and package removal, creation and installation of binary packages, and the ability to create new distributions from scratch.
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.
The psys library provides a simple interface to the system package manager of a Linux system. It allows installation programs to notify the package manager of the installation, uninstallation, and update of third-party software packages, and to request these packages to be added to or removed from the system package database. The psys library interface is generic and not tied to a specific package management system or Linux distribution; it is meant to be a proposal for a future version of the LSB standard.
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.
