INSTALLATION:
------------
If using the source distribution, first compile the source by typing 
'make'. Copy the compiled plugin into your XMMS visualizations
plugin directory by typing 'make install' (you may have to be root
to do this)

If using the binary distribution, copy the file libxtp.so to your XMMS
Visulaizations plugin directory. This should be something like
/usr/lib/xmms/Visualization. If you do not know the name of the 
visualization plugin directory on your system, you can type 
xmms-config --visualization-plugin-dir at the command prompt.


USE:
---
From the XMMS preferences page, click on the "Visualization Plugins" tab.
OpenGL Terrain Plugin should be on the list. Click on it and then click 
the checkbox labeled "Enable plugin".

While the plugin is running, you can toggle full-screen mode by pressing
the 'F' key. You can switch terrain drawing modes by pressing the 'M' key.
