Is 'ksh' available.

[John Schneider]

A few people at my company (including myself) have expressed an 
intrest in 'ksh'. I have seen 'ksh' scripts on the net occasionally
and have read about it in Kochan & Wood's "Exploring the Unix System".
I do not know much else about it and would appreciate any sending 
me some documentation and or source (this is the "is it available"
question). I would also like to know when ATT plans to distribute 
it (for my own knowledge). 	
				Thanks in advance,
