GPL3 is not incompatible with GPL2, because GPL2 has a clause
that allows you to upgrade to any later version of the GPL.
This is wrong. By itself, GPLv2 is indeed incompatible with
GPLv3. However, many (most?) projects using the GPLv2 in fact
say "or any later version" in their licensing conditions, as
recommended by the FSF. I don't think that this is a proper
part of the license, however.
It is:
« 9. The Free Software Foundation may publish revised and/or new
versions
of the General Public License from time to time. Such new
versions will
be similar in spirit to the present version, but may differ in
detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program
specifies a version number of this License which applies to it
and "any
later version", you have the option of following the terms and
conditions
either of that version or of any later version published by the
Free
Software Foundation. If the Program does not specify a version
number of
this License, you may choose any version ever published by the
Free Software
Foundation.»
And the following text is recommended to be put in each source
file:
