kickstart.py: %installclass??

[Mark Heslep <mark@xxxxxxxxx>]

From scanning kickstart.py  it looks like a custom kickstart class can 
be defined by including a "%installclass" in the ks config file (see 
def  Kickstart(f,s) ).  This would be a big help to me as there several 
required steps in the current default ks clas I want to turn off.    I 
dont see any documentation of this anywhere. So is this experimental? 
Deprecated? Otherwise going away before we lock onto it?
