<P><B>The Zint project is committed to providing the open source
community with encoding software for all public domain barcode
standards. For this we need access to the standard documentation and,
unfortunately, this is not free. Your donation will contribute
towards the purchase of standard documents from the ISO and ANSI.
Standards which we hope to add to Zint in this way include Aztec
Code, Codablock-F, Code 49, Supercode, Code One and (when it becomes
available) Ultracode. If you have a preference regarding which
standard you would like your donation to go towards then please let
us know and we will reserve your donation for that standard. Thank
you.</B></P>
