platform to test CPU affinity and NUMA-aware features in FreeBSD.

Updated gencat(1) page from T. Lambert:
"Here is a new gencat(1) man page. It contains examples
and information not in the current man page (e.g., file
format) per the X/Open documentation. It also updates some
aspects of the X/Open documentation (e.g., the X/Open
document neglects to say how to embed a $quote character
into a string)."
