No need to apologise, it is very needed that everyone understands under what 
terms our contributions are made.

I can not prevent someone else relicensing my code? My code is mine and i 
decide under what license i release it, and the code i do for poppler is GPL. 
You can not use it in a non-GPL project.

No, they can include poppler as they are not relicensing it.

Nothing, but remember you must not only provide the poppler sources but ALSO 
your application sources.

Of course, but i will be able to access the resulting code, that can be seen 
as a profit i take back.

I do business? i wonder how, i've got 0 € for my work on poppler/kpdf, if i 
count the trip i did to KDE conference to present a poppler talk that number 
would even be negative, that is without counting the hours spent.

Now i'm going to explain you again the problem i have with Derek using my code 
as you obviously did not understand the "relicense" part.

Derek is selling you a license that allows you to do an aplication based on 
xpdf sources and do NOT publish the code of you application, right?

He can do that because he owns all the xpdf code, so he has chosed to have 
both a GPL version you can use if you want to code GPL programs (aka poppler, 
kpdf, gpdf, etc) and a commercial version you can use and do not release the 
code of your app as GPL version mandates.

It is that (relicensing) what he can not do if he incorporates my patches, 
because he can not RELICENSE my code under something else different than the 
GPL without my agreement, and he does not have it.

It is sad you are not able to understand that.

Yeah yeah, speak of OSS, don't tellme about how OSS works, tell Derek. He has 
NEVER accepted any kind of cooperation (that is basically why poppler 
exists), also i have lots of unanswered mails i sent him.

Remember GPL is not only OSS but also FREE software, so the applications the 
us poppler have to be GPL also.

Albert

BTW i apreciate your contributions a lot since it's obvious you know about PDF 
but you should learn more about licensing before telling me i'm acting wrong.
