Zero Install is a decentralized cross-distribution software installation system. It allows software developers to publish programs directly from their own Web sites, while supporting features familiar from centralized distribution repositories such as shared libraries, automatic updates, and digital signatures. It is intended to complement, rather than replace, the operating system's package management. 0install packages never interfere with those provided by the distribution.
mrepo (formerly known as Yam) builds a local APT/Yum RPM repository from local ISO files, downloaded updates, and extra packages from RHN (Red Hat Network) and 3rd party repositories. It takes care of setting up the ISO files, downloading the RPMs, configuring HTTP access, and providing PXE/TFTP resources for remote installations. It was primarily intended for doing remote network installations of various distributions from a laptop without the need for CD media or floppies, but is equally suitable for an organization's centralized update server.
Virtual Appliances are nano-sized virtual machines for deploying instant infrastructure and applications. They are Ubuntu Server Edition 8.04 based and available for VMware, QEMU, KVM, Parallels, Xen, Virtual Iron, Virtural PC, and Virtual Server. Available Virtual Appliances are a LAMP Server, LAPP Server, Apache Tomcat Server, and Cacti Virtual Appliance. These are the smallest, most functional, and easiest to use Virtual Appliances available. They are certified for use on VMware and Parallels.
Repo-proxy is a package repository proxy. When a package manager is configured to use repo-proxy, all package requests will be copied and stored in a local cache directory for future use. If you have more than one machine on a local network, they can all share the same package download cache, saving bandwidth and lengthy download times. Repo-proxy can be run using several different methods to accept requests from clients (package managers such as apt-get or smart) for Release and/or Package files.
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.
Easy SVN is a subversion browser via the Web. It's easy because only a command line svn program and Perl are required to run it; no extra software needs to be installed. After configuring the Perl script as cgi-bin program, SVN repositories can be navigated, and entries viewed for contents, history, and diffs.
