Himerge
Haskell Graphical Interface for Emerge (Gentoo Portage system).
What is it?
Himerge is a graphical user interface (GUI) for the Gentoo portage system written entirely on Haskell using the Gtk2Hs library.
Purpose
The main idea is to simplify browsing the entire portage tree as well as of running the most basic and common operations from the emerge command. Himerge also offers several handy tools, like a global/local use flag and package branching browser. It also serves as a front-end for several small utilities (like eix and equery) for performing different operations like calculating reverse dependencies and fast indexing of packages information. Himerge also comes with an embedded gecko engine to show package information on web format.
Himerge is Free Software released under the GPLv2 or later.
Features
Access the whole portage tree using the 'Category', 'Package', 'Version' views.
Run the most common 'emerge' operations with just one click: emerge, unmerge, binpkg, fetch, usepkg and more.
Synchronize the portage tree just pressing a button.
USE Flag browser for easily enabling/disabling global or per package use flags.
Package Branch browser for adding or removing packages from the /etc/portage/ files.
