This is a free software license which is not a strong copyleft; it has some complex restrictions that make it incompatible with the GNU GPL. It requires that all attribution notices be maintained, while the GPL only requires certain types of notices. Also, it terminates in retaliation for certain aggressive uses of patents. So, a module covered by the GPL and a module covered by the CDDL cannot legally be linked together. We urge you not to use the CDDL for this reason.
Also unfortunate in the CDDL is its use of the term "intellectual property".
Mondjuk ez még mindig nem szabadabb (attól, hogy 3-betűs megaszondók kijelentik). :-)
It doesn't matter if you like my song as long as you can hear me sing
