<title>Compiz Fusion</title>
<para>
	Compiz Fusion is just a set of plugins fr Compiz. Your best interest is to have 
	them found both by Compiz and by Compiz Configuration Settings (also in Compiz Fusion
	distribution). By default they look in Compiz installation path and in home directory.
	You do not need to track /nix/store manually - everything is already in 
	/var/run/current-system/sw/share.

	<orderedlist>
	<listitem><para><filename>$HOME/.compiz/plugins</filename> 
	should contain plugins you want to load. All the installed 
	plugins are available in 
	<filename>/var/run/current-system/sw/share/compiz-plugins/compiz/</filename>,
	so you can use symlinks to this directory.
	</para></listitem>

	<listitem><para><filename>$HOME/.compiz/metadata</filename> 
	should contain metadata (definition of configuration options) for plugins 
	you want to load. All the installed metadata is available in 
	<filename>/var/run/current-system/sw/share/compiz/</filename>,
	so you can use symlinks to this directory.
	</para></listitem>

	<listitem><para>
	Probably a way to load <literal>GConf</literal> configuration backend by default 
	should be found, but if you run <literal>Compiz</literal> with 
	<literal>GConf</literal> configuration (default for <literal>X server</literal> job
	for now), you have to link 
	<filename>/var/run/current-system/sw/share/compizconfig/backends/libgconf.so</filename>
	into <filename>$HOME/.compizconfig/backends</filename> directory.
	</para></listitem>

	</orderedlist>

	Now you can launch <literal>ccsm</literal> and configure everything.

	Enable smileys. If you do not want to, you can create

	<programlisting>
	Name=Empty
	Description=No predefined smileys
	Author=Nobody
	</programlisting>	
	Enabling this theme will enable smileys, but define none.
