This is whay I found on a website:
quote: When we say that GPLv2 and GPLv3 are incompatible, it means there is no legal way to combine code under GPLv2 with code under GPLv3 in a single program. This is because both GPLv2 and GPLv3 are copyleft licenses: each of them says, “If you include code under this license in a larger program, the larger program must be under this license too.” I wonder what is the best way for me to make use of PEL in my project? The easiest way for the end-user would be if I just include a folder 'PEL' in my application and then require classes from PEL when needed. But I am not sure if I can do it now because all other code in my project in under GPL v2? The other way is to instruct the user to download and unpack the PEL themselves somewhere on their system and then add that directory to include path. This will not violate any incompatability with 2 GPL licensed but a little 'less easy' for the end user. Any thoughts on this? PS. if you upgrade to GPL 3, then projects that are under GPL 2 will have the same issue as I'm having now.
