 SURAMP - Linearly taper the start and/or end of traces to zero.	

 suramp <stdin >stdout [optional parameters]				

 Required parameters:							
 	if dt is not set in header, then dt is mandatory		

 Optional parameters							
	tmin=tr.delrt/1000	end of starting ramp (sec)		
	tmax=(nt-1)*dt		beginning of ending ramp (sec)		
 	dt = (from header)	sampling interval (sec)			

 The taper is a linear ramp from 0 to tmin and/or tmax to the		
 end of the trace.  Default is a no-op!
