 dev-libs/glib:systemtap - Build support for profiling and tracing using dev-util/systemtap
 dev-libs/glib:utils - Install gtester-report utility to generate test report files for your software.
 flx/initramfs:xz - Compress using XZ/LZMA algorithm
+media-sound/pulseaudio:X - Build the X11 publish module to export PulseAudio information through X11 protocol for clients to make use. Don't enable this flag if you want to use a system wide instance. If unsure, enable this flag.
+media-sound/pulseaudio:asyncns - Use libasyncns for asynchronous name resolution.
+media-sound/pulseaudio:doc - Build the doxygen-described API documentation.
+media-sound/pulseaudio:equalizer - Enable the equalizer module (requires sci-libs/fftw).
+media-sound/pulseaudio:gdbm - Use sys-libs/gdbm to store PulseAudio databases. Recommended for desktop usage. This flag causes the whole package to be licensed under GPL-2 or later.
+media-sound/pulseaudio:glib - Add support to dev-libs/glib-based mainloop for the libpulse client library, to allow using libpulse on glib-based programs.
+media-sound/pulseaudio:gnome - Use GConf to store user preferences on streams and so on. Don't enable this flag if you want to use a system wide instance. If unsure, enable this flag.
+media-sound/pulseaudio:oss - Enable OSS sink/source (output/input). Deprecated, upstream does not support this on systems where other sink/source systems are available (i.e.: Linux). The padsp wrapper is now always build if the system supports OSS at all.
+media-sound/pulseaudio:realtime - Makes PulseAudio use RealtimeKit (sys-auth/rtkit) to get real-time priority while running.
+media-sound/pulseaudio:ssl - Use dev-libs/openssl to provide support for RAOP (AirPort) streaming.
+media-sound/pulseaudio:system-wide - Allow preparation and installation of the system-wide init script for PulseAudio. Since this support is only supported for embedded situations, do not enable without reading the upstream instructions at http://pulseaudio.org/wiki/WhatIsWrongWithSystemMode .
+media-sound/pulseaudio:systemd - Build with sys-apps/systemd support to replace standalone ConsoleKit.
+media-sound/pulseaudio:webrtc-aec - Uses the webrtc.org AudioProcessing library for enhancing VoIP calls greatly in applications that support it by performing acoustic echo cancellation, analog gain control, noise suppression and other processing.
+media-sound/pulseaudio:xen - Builds a special paravirtualized module for running in a Xen guest.
 net-dialup/freeradius-client:scp - Add service type hints derived from username prefix
 net-dialup/freeradius-client:shadow - Enable shadow password support
 net-misc/icmptx:client - Enable client support
