[reportlab-users] upc-a barcodes

[Steve Romanow]

  I understand that upc-a and its ilk are related to EAN-13, however, it 
does not seem trivial to get UPC-12 barcodes out of ean.py.

Between upc-12, ucc's, and ean's it is dangerous to use the length of 
the string as an indicator as to how it should be encoded.  Is this 
already sorted out in teh community and I am just behind?

Thanks,

Steve
