 PSCUBE - PostScript image plot with Legend of a data CUBE       

 pscube n1= 
	 n2= 
	 n3= [optional parameters] <binaryfile >postscriptfile
	 
 
 	or
    									
 pscube n1= 
	 n2= 
	 n3= 
	 front= 
	 side= 
	 top= [optional parameters] >postscriptfile

 Data formats supported:						
	1. Entire cube read from stdin (n1*n2*n3 floats) [default format]
	2. Faces read from stdin (n1*n2 floats for front, followed by n1*n3
	   floats for side, and n2*n3 floats for top) [specify faces=1]	
	3. Faces read from separate data files [specify filenames]	

 Required Parameters:							
 n1=                     number of samples in 1st (fastest) dimension	
 n2=                     number of samples in 2nd dimension		
 n3=                     number of samples in 3rd (slowest) dimension	

 Optional Parameters:
