Can we make that 2007-2008, please? It took me a while to understand 
what's meant.

At least as of GPLv3, the recommendation changed to use a URL in place 
of the postal address:

[is GPLv2+]


== library/pippy/console.py, library/pippy/query.py ==
[is GPLv2+]


== library/pippy/physics/LICENSE ==
[add GPLv3 license text]

== library/pippy/physics/* ==
[is GPLv3+]

We have a problem here: GPLv2 and GPLv3 are incompatible [1]. We should 
try to upgrade the GPLv2 parts to GPLv3 to fix this.
There are two options:

1. Since all Pippy files seem to be GPLv2+, we could just go the 
"automatic" upgrade route, assuming this is possible in the countries of 
all authors (*).
2. We ask all Pippy contributors to re-license their modifications under 
the GPLv3.


(*) AFAIK this hasn't been tested in court yet and at least in Germany 
not all lawyers agree it's possible - especially if the new license text 
wasn't known to the author when (s)he released the software.

level)
