I don't see any other claims of copyright. How do I verify that?
Well, normally with only one copyright claim, you can assume that this
person (or entity) owns the copyright on the entire program. In this
case, this is unlikely because:
- Some parts of the code have been written by others.
- The license which is chosen seems to be a "I don't care about
copyright" type, which is mostly intended to keep the lawyers away.
(This is my interpretation, not necessarily theirs.)
- For one person to hold the entire copyright when multiple people have
written code, a copyright transfer must have taken place. I find it
unlikely that these people took the trouble to do that.
For the parts you own the copyright on, you can even be sure that you
didn't transfer copyright. :-)
- A license for the only copyright claim. This seems to be about the
entire program. If this is correct, that is good. :-) However, all
copyright holders need to agree. It's probably a good idea to send
them (and Jon Bennett, too) a mail asking them who they think holds
copyrights on (parts of) the code, so this can be properly noted.
Oh, and of course if they hold copyright, they should confirm that they
released the code under the same license.
