Gentoo Overlay containing various packages I have been unable to find @ Gentoo Portage Overlays website or elsewhere. Testing and updating of these ebuild package build scripts is irregular. So YMMV - you have been warned!
Main Overlay packages
app-arch/cabextract : Tool to extract files from Microsoft cabinet archive files. app-arch/unshield : Tool and library to extract CAB files from InstallShield installers. app-benchmarks/glxosd : GLXOSD is an extensible on-screen display (OSD)/overlay for OpenGL applications running on Linux with X11 which aims to provide similar functionality to MSI Afterburner/RivaTuner OSD. app-benchmarks/i7z : A better Intel i7 (and now i3, i5) CPU reporting tool for Linux. app-benchmarks/phoronix-test-suite : Phoronix's comprehensive, cross-platform testing and benchmark suite. app-forensics/pev : PE file analysis toolkit - for examining Windows PE binary files. dev-cpp/pion : C++ framework for building lightweight HTTP interfaces. games-fps/dhewm3 : Doom 3 GPL source modification (with updates including SDL2 support). games-util/lutris : Lutris is an open gaming platform for Linux. It helps you install and manage your games in a unified interface. kde-misc/kmozillahelper : helper application that allows Mozilla Firefox to use Plasma file dialogs, file associations, protocol handlers and other desktop integration features. mail-client/thunderbird : Thunderbird mail client, with optional OpenSUSE Patchset for better Plasma Desktop integration. media-sound/neroaac : Nero AAC reference quality MPEG-4 and 3GPP audio codec. media-video/ffx264 : Script to encode video files to H.264/AVC video using the FFmpeg encoder. media-video/filebot : Java-based tools to rename TV shows, download subtitles, and validate checksums. media-video/h264enc : h264enc is an advanced and powerful interactive menu-driven shell script written for the GNU/Linux operating system to encode video files net-dialup/dterm : dterm is a simple terminal emulator for serial connections. net-dns/ndjbdns : Fork of djbdns, a collection of DNS client/server software. sys-apps/cpuid : Utility to get detailed information about CPU(s) using the CPUID instruction. sys-apps/hw-probe : A tool to probe system hardware, check operability and upload results. sys-fs/exfat-nofuse : Non-fuse kernel driver for exFat and VFat file systems. sys-fs/exfat-utils-nofuse : exFAT filesystem utilities (without fuse). www-client/firefox : Firefox web browser, with optional OpenSUSE Patchset, for better Plasma Desktop integration. x11-apps/starfield : Reminiscence to the screensaver that shipped, with Windows, until Windows XP.
Customised Wine package set
These Wine packages are more than a cosmetic fork of the main Gentoo Portage and other Overlay Wine packages. So don't "mix and match" these!
See: Wiki: Wine Packages for more information.
Note: the ::bobwya Overlay Wine packages do not support the Gallium 9 / D3D9 patchset. This is purely down to testing systems only using the Nvidia Proprietary graphics driver.
Custom GL lib switcher implementation package set
These packages are masked and are NOT extensively tested (but I use them personally!) Loosely based off the Arch-Linux GL lib switcher. Has some rudimentary support for PRIMUS setups. The x11-drivers/nvidia-drivers package is customised to support the GLXOSD fork in the ::bobwya Overlay.
app-eselect/eselect-opengl : Gentoo OpenGL implementation switcher (heavily customised) media-libs/mesa : OpenGL-like graphic library for Linux (patched version - to work with custom eselect-opengl switcher) x11-base/xorg-server : X.Org X servers (patched version - to work with custom eselect-opengl switcher) x11-drivers/nvidia-drivers : NVIDIA Accelerated Graphics Driver (patched version - to work with custom eselect-opengl switcher)
Infinality Fonts package set
Package Set to provide updated Infinality Fonts (subpixel font rendering enhancements for freetype2 and associated packages). These four packages are designed to be used in conjunction with each other. The media-libs/fontconfig-infinality package is in the main Gentoo Portage tree.
media-libs/fontconfig-infinality : Provides configuration to be used in conjunction with the freetype-infinality subpixel hinting. media-libs/fontconfig : A library for configuring and customizing font access - with updated infinality support. media-libs/fontconfig-ultimate : A set of font rendering and replacement rules for fontconfig-infinality. media-libs/freetype : A high-quality font engine - with updated infinality support.
