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  manufacturer  code,  and  a  five
       digit  product  code.   For  example,  "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 changing the defines at the be-
       ginning 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 de-
       fault, -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||
