ISO Master is an easy to use GUI CD image editor for Linux, BSD, and Windows. Basically, you can use this program to extract files from an ISO, add files to an ISO, and create bootable ISOs, all in a graphical user interface. It can open both ISO and NRG files, but can only save as ISO. It is based on bkisofs, a library for reading, modifying, and writing ISO images.
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.
YOURI (Youri Offers an Upload & Repository Infrastructure) aims to build tools that make the management of a coherent set of packages easier. It assists in the many tasks involved with running a package distribution project, such as allowing individual maintainers to upload packages in a central repository, creating package indexes for package, synchronizing development resources such as CVS or bugzilla, advertising new packages, signing packages, and checking the consistency of individual packages or the global repository.
Japt-Proxy is a fast and reliable caching proxy for Debian's APT system. It is intended for environments where several Debian systems have to be kept up-to-date and downloading the same files over and over again from the Debian mirrors is undesirable. Even with high volume internet connections, it can dramatically reduce the time required to install or update Debian on many machines.
With 'nixstaller' you can easily make installers for Unix-like systems. Some of the project goals: support for many different platforms, support for different (optional) frontends used by the installer (currently FLTK, ncurses, GTK 2, and Qt are planned), ease of use for the install creator and the end user, different ways of installing (extract files to a location, compile software on the user's system, and maybe even integration for the package manager running on the user's system). Nixstaller can be fully translated and is programmed in C++ and sh.
