HATS - Anybody using it on a regular basis

[Pete Helgren <Pete@xxxxxxxxxx>]

I am saddled with a HATS project and just need to find out if anyone is 
working regularly with this beast and, if so, what resources they used 
to get up to speed. 

I need to fill in a lot of blanks quickly.  Like, within days.  IBM has 
lots of stuff, most of it is repetitive and has paper-thin depth of 
content (no pun intended) .  I looked at Redbooks, Redpieces, Red 
Buttons, Red Skelton, Little Red Riding Hood but no joy....

If someone has a  "must have" HATS resource (books, tutorials, online 
training, article...) that can be quickly and easily obtained, could you 
point me to it? 

Thanks,
