NAME
       pbmupc - create a Universal Product Code bitmap

SYNOPSIS
       pbmupc [-s1|-s2] type manufac product

DESCRIPTION
       Generates  a  Universal  Product  Code  symbol.  The three
       arguments are: a one digit product type, a five digit man-
       ufacturer  code, and a five digit product code.  For exam-
       ple, "0 72890 00011" is the code for Heineken.

       As presently configured, pbmupc produces a bitmap 230 bits
       wide and 175 bits high.  The size can be altered by chang-
       ing the defines at the beginning of  the  program,  or  by
       running the output through pnmenlarge or pnmscale.

OPTIONS
       The -s1 and -s2 flags select the style of UPC to generate.
       The default, -s1, looks more or less like this:
        ||||||||||||||||
        ||||||||||||||||
        ||||||||||||||||
        ||||||||||||||||
       0||12345||67890||5
       The other style, -s2, puts the product type  digit  higher
       up, and doesn't display the checksum digit:
        ||||||||||||||||
        ||||||||||||||||
       0||||||||||||||||
        ||||||||||||||||
        ||12345||67890||
