Paludis is a package manager for Gentoo (and derived distributions) and Exherbo. It consists of a core library and a number of console-based clients. Package formats supported include Gentoo ebuilds and kdebuilds (as defined by the Package Manager Specification), the Exherbo exheres-0 format, and various miscellaneous utility pseudo-formats for managing accounts, unwritten and unavailable packages, and packages for which no package exists.
W-Packager is a packager similar to dpkg that can be used by anyone to create and maintain Debian packages under Linux or other Unix systems. The aim of the project is primarily to have a workable version of a packager that can be compiled on many systems, including those that do not support fork(). At this time, W-Packager is used within UniGW. It can also be used under Linux.
Rally is a software component with a user interface which allows a user to install, update, and remove packages on RPM based operating systems. Primary functions (downloading software packages from network repositories and their installation) may be performed in parallel. The user interface is split into two independent parts: a graphical one and a command line utility. The graphical interface contains package searching and category browsing functions. Rally assumes the Fedora project as a reference platform.
NUU (Network Update Utility) is a GUI RPM package manager based on Yum that supports downloading, installation, and updating of packages from remote repositories, and removal of installed packages. It has the ability to examine both installed and available packages, and includes a repository configuration editor. It also supports package groups and suites of packages. Finally, it recognizes a simple authentication mechanism called buffet based on a server-side cgi-bin program.
changedfiles is a framework for filesystem replication, security monitoring, and/or automatic file transformations--essentially any application where you'd poll files or directories and either do something to them or send them somewhere else (or both). The difference is that the kernel tells you when they change instead of you having to poll. It's an easy real time FTP push mirror to one or multiple sites. It's also a full fledged MySQL client, so you can do realtime database operations (for example, batch imports). It consists of two parts: a kernel module (works with Linux kernel version 2.4) which reports to a device whenever a file on the filesystem changes, and a daemon which runs in user space and can be configured to do almost any action when a change to a file matching the one of the patterns it looks for is reported. The kernel module is SMP safe and has been tested on Intel, PowerPC, and Alpha.
XPKGTOOL is a GUI front-end for pkgtools that allows you to manage, install, remove, and upgrade packages with ease, through a nice and user friendly X-based interface. It comes with a built-in update manager, called SlackGrade, that will help you to keep your Slackware system up to date, checking, downloading, and upgrading the system with the latest packages available from the main Slackware distribution sources on the Web.
UPMS (Universal Package Managment System) is based on the BSD ports system, and can be used on any FHS 2.0 Linux-compatible distribution. UPMS has two level of dependencies checking: required and suggested. It also has an option to optimize everything that you build and install with it for your architecture.
