Hi, Jean, My understanding is you can't relicense Apache software, but that doesn't necessarily prevent you from including it in your own software as long as you comply with the terms of the Apache license. I included links to a couple FAQs below which might help. http://www.apache.org/foundation/licence-FAQ.html#My-CD "May I include Apache software or documentation on a CD-ROM I'm making?" "Yes, as long as you comply with the terms of the license. See the What does it MEAN section for help with interpretation." http://www.apache.org/foundation/licence-FAQ.html#Distribute-changes "I've made improvements to the Apache code; may I distribute the modified result?" "... Just remember that the original code is still covered by the Apache license and you must comply with its terms. Even if you change every single line of the Apache code you're using, the result is still based on the Foundation's licensed code. You may distribute the result under a different license, but you need to acknowledge the use of the Foundation's software...." Those FAQs have helpful links to additional information. Also see the FAQ on the GPL: http://www.apache.org/foundation/licence-FAQ.html#GPL I hope this helps. I am not a lawyer; it might be wise to check with your own lawyer to make sure that everything is in order with what you plan to do. Any other tips out there? Feel free to chime in! -jean
