 PSLABEL - output PostScript file consisting of a single TEXT string	
          on a specified background. (Use with psmerge to label plots.)

 pslabel t= [t=] [optional parameters] > epsfile			

Required Parameters (can have multiple specifications to mix fonts):	
  t=                 text string to write to output			

Optional Parameters:							
  f=Times-Bold       font for text string				
                      (multiple specifications for each t)		
  size=30            size of characters in points (72 points/inch)	
  tcolor=black       color of text string				
  bcolor=white       color of background box				
  nsub=0             number of characters to subtract when		
                     computing size of background box (not all		
                     characters are the same size so the		
                     background box may be too big at times.)		

 Example:								
 pslabel t="(a) " f=Times-Bold t="h" f=Symbol t="=0.04" nsub=3 > epsfile

 This example yields the PostScript equivalent of the string		
  (written here in LaTeX notation) $ (a)\\; \\eta=0.04 $		

 Notes:								
 This program produces a (color if desired) PostScript text string that
 can be positioned and pasted on a PostScript plot using   psmerge 	
     see selfdoc of   psmerge for further information.
