how to replace Prelude

[S.D.Mechveliani]

Sorry for easy question,
who could explain please, can Haskel work with the user-provided 
prelude instead of standard?
For example, may it work moving  +,-,*  to different classes?
If yes, probably, the user has to put somewhere the path to
Prelude.hs  or such, to do it culturally ...
(going to try first Hugs-Feb2000, then GHC-4.06). 

Thank you in advance for explanation.
