The exact license terms. We might be able to help if you tell us which part(s) of the license you don't understand.
There are some nice articles on many of the more common licenses on Wikipedia as well if you want a broader understanding. "Open-source"
only implies that the source code is available. What one is allowed to actually do with the code will vary by project/author.

If you can't find the license, I'd suggest sending an email to that address asking for a copy.
