In a program I am writing using MMA3.0, the function Max[] is used
extensively.  Is there any way to tell MMA that 


Such that 

Max[s, s*a]

would return


Maple V has the function assume().  I know MMA does not have this, but
is there any way to create it.  The Integrate[] function takes the
option Assumptions->{}.  There must be a way to use this capability in
other parts of MMA (I think).

Any help is appreciated.
