Gentoo Linux is a versatile and fast Linux distribution for x86, PowerPC, Sparc, and Sparc64 that's geared towards Linux power users. Unlike other distros, it has an advanced package management system called Portage. Portage is a true ports system in the tradition of BSD ports, but is Python-based and sports a number of advanced features including dependencies, fine-grained package management, "fake" (OpenBSD-style) installs, path sandboxing, safe unmerging, system profiles, virtual packages, config file management, and more.
ProviderTool Internet server administration program with email protection. The software is divided into a subcomponent Admin Tool, Customer Tool, and a Reseller Tool. Each subcomponent tool manages a separate zone that is setup for the specific needs of your administrator, end user, and reseller. If you have a Red Hat, SuSE, or Debian Internet or intranet server, you will be able to add, delete, and change settings and users with just a couple of clicks. ProviderTool is delivered with a separate Apache and PHP server environment. There is also an email protection tool included.
EPOR is an extensible package organiser for Unix-like systems. It's written to trace filesystem changes (something being installed) and save this information in a simple text database (this, as any other provided feature, is customisable via the embedded Guile interpreter). Database entries contain information supplied by the command line (package name, version, etc.) and traced by filesystem changes (new directories, files, etc.). This is achieved using the "LD_PRELOAD method''.
