program hb2ps 
c----------------------------------------------------------------------
c translates a harwell - boeing file into a post-script file. Usage:   
c                   hb2ps < HB_file > Postscript_file 
c where hb2ps is the executable generated from this program,
c HB_file is a file containing a matrix stored in Harwell-Boeing
c format and Postscript_file is a file to contain the post-script file.
