NROT missing from IO documentation

[Dave_R]

So we are trying to figure out how to setup management files and the number of years of rotation - NROT input is missing from the 2012 IO manual.  It is in the 2009 manual (20.1.6), and in the 2012 help documentation it is at least mentioned.  Does this indicate some kind of change or just a missed entry in the IO manual.  If you have put rotations in 2012 or have knowledge of the status of this input in 2012, enlightenment would be much appreciated.
