[Amps] "Stacking" power supplies?? how?

[chas]

How do I connect three 30A power supplies together so as to obtain 90A ?

I would assume it would be parallel but I cannot believe it is as simple as 
daisy chaining three auto batteries - pos to pos to pos, etc

either I am having a severe case of CRS or my logic meter has shut down.

thanks for any simplistic explanation forthcoming
