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
      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||
