cerbeRun is a software runner. The applications are stored inside a .tar (version 0.3 will use the ISO9660 format) file renamed with the extension .run. cerbeRun's format allows you to switch between different architectures using an .xml file, in which are specified different rules for different archictures. This is all done in user space without root access.
CLU is an installation, removal, and upgrade management tool written for speed, size, and power. It utilizes LibAST to provide an object-oriented interface for abstracting package managers, packages, package groups, and repositories. The current implementation focuses on RPM, but additional formats can be added.
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.
DeltaRPM is a tool that generates RPMs that contains the difference between an old and a new version of an RPM. This makes it possible to recreate the new RPM from the deltarpm and the old one. You don't have to have a copy of the old RPM, as it can also work with installed RPMs. The package also contains tools for creating and applying delta ISOs.
Gspoof is a GTK+ program written in the C language which makes it easier and more accurate to build and send TCP packets with or without a data-payload. It's possible to modify TCP/IP fields and also ethernet header working to Link Level. You can send one or more packets together. It runs also in "console mode" without X and so you can compile it without GTK+.
Loki Setup is a graphical installer for Unix applications. It features descriptions of the package to install in XML, a GTK interface that can be dynamically redefined by the user with Glade, raw and ncurses console interfaces, and the automatic generation of uninstall scripts. It has been successfully used on many Linux and UNIX platforms. It includes tools for uninstalling, patching, and recovering installations. It operates independently from any package managers.
