Does anyone have any good documentation or reference on customizing KDE4 
as used in SL7 system-wide/default?

In SL5 I could drop in static files in /usr/share/config/ to get the job 
done.

They've gone and added more layers of complication (dynamic indices) in 
their configuration files and some sort of plasma-desktop scripting 
language that has questionable documentation.  At this point, I would be 
happy to set a default wallpaper and be able to add some icons to the 
panel.  Later I would like to set some default policies, such as focus 
and eye candy type things.
