The COPYING file is the standard GPLv2 license text. Note that the first part says "If the Program specifies a version number of this License which applies to it and "any later version", ..." But the header only says "GPLv2 found in the COPYING file" so it doesn't add the words "any later version". And the second quote is from the example of how to apply the licenses. But they clearly didn't follow that because the header text they use is slightly different (again doesn't include "any later version"). It might still be that they actually mean GPLv2+, but it would be good if they explicitly state that. -- You are receiving this mail because: You are watching all bug changes.
