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||
