Is there any documentation regarding what License the XMPPFramework is under? Are the Modules included under that License as well?
The last mention of Licensing I found was on the mailing list from 2010-11 (https://groups.google.com/forum/#!topic/xmppframework/12U83jxwqsA) indicating it fell under New BSD. edit: XMPPStream is also specifically mentioned as BSD in [copying.txt|https://github.com/robbiehanson/XMPPFramework/blob/master/copying.txt]
All of the code outside of the Vendor Folder (which is other open source projects) falls under the New BSD Licence.
