Since development on XMMS ended long ago (last release was in 2007), we have
switched support to MPRIS (Media Player Remote Interfacing Specification),
an API for controlling *any* media player which supports it. We use the
playerctl C library, available from https://github.com/acrisci/playerctl.
Because of the switch, several more XMMS-specific features have been removed.
In particular,
* The channels are no longer displayed, and the volume is always displayed.
* The bitrate is no longer displayed, and the title is always displayed.
* The eject feature no longer is functional, although the eject button is
still present.
* Toggling between the various XMMS windows is no longer supported.
