 SUCONV - convolution with user-supplied filter			

 suconv <stdin >stdout  filter= [optional parameters]			

 Required parameters: ONE of						
 sufile=		file containing SU trace to use as filter	
 filter=		user-supplied convolution filter (ascii)	

 Optional parameters:							
 none 									

 Trace header fields accessed: ns					
 Trace header fields modified: ns					

 Notes: It is quietly assumed that the time sampling interval on the	
 single trace and the output traces is the same as that on the traces	
 in the input file.  The sufile may actually have more than one trace,	
 but only the first trace is used.					

 Examples:								
	suplane | suwind min=12 max=12 >TRACE				
	suconv<DATA sufile=TRACE | ...					
 Here, the su data file, "DATA", is convolved trace by trace with the
 the single su trace, "TRACE".					

	suconv<DATA filter=1,2,1 | ...					
 Here, the su data file, "DATA", is convolved trace by trace with the
 the filter shown.

  CAVEATS: no space-variable or time-variable capacity.
     The more than one trace allowed in sufile is the
     beginning of a hook to handle the spatially variant case.

      Implemented correct use of delrt
