Himerge is a GUI for emerge (Gentoo's Portage system) written in Haskell using gtk2hs. The main idea is to simplify browsing the entire portage tree, and allow running the most basic and common options from the emerge command. It also offers several handy tools, like global and local use flags browsers, inspired by UFED (the Gentoo Linux USE flags editor). It also uses eix (a small utility for searching ebuilds with indexing for fast results) as a back-end command to show package information in HTML/CSS format, so you can access a package's Web site for a quick glance.
UniPackage is an alternative to distribution-specific packaging systems like dpkg and RPM. UniPackage is a simple system that works on any Linux distribution. UniPackage packages are tar.bz2 archives which contain a self-contained "AppDir" which can be moved anywhere in the filesystem without disturbing the application's installation. In most cases, this packaging does not require changes to the application's code. The issue of dependencies is avoided by bundling all required libraries in the AppDir.
