Volume Icon aims to be a lightweight volume control that sits in your systray.

Features :
Change volume by scrolling on the systray icon
Ability to choose which channel to control
Configurable stepsize (percentage of volume increase/decrease per scrollwheel step)
Several icon themes (with gtk theme as default)
Configurable external mixer
Volume Slider

To enable OSS support, you will need to run the script like this:
OSS=yes ./volumeicon.SlackBuild

By default Volume Icon will be built with ALSA as its backend.
Note that it is not possible to build with both ALSA and OSS support at the moment,
so using this flag will disable ALSA support.
