It recently came to my attention that some of the licenses used for the libraries available here weren’t very “corporate friendly”. As a result I’ll be adding a second license to any library or program here that’s covered by the GPL or LGPL. At your option you’ll also be able to use the code here under the terms of the Apache License ( http://opensource.org/licenses/apache2.0.php ). I’ll make new builds of the libraries starting with the Light HL7 Library first and include the new license soon. Contact me if you’re in a hurry for this license and I’ll do what I can to help you.
