CC0 is a problematic license because its not really a software license

Hi,

Putting stuff in the public domain feels like a "wide open" way of releasing your software, but it has a great deal of ambiguity since it doesn't really say if you're going to enforce your copyright and patents or not.

Please consider using a real Free Software license. Something that forces your code to remain free, like the GPL. If you have issues with the GPL, please consider the MIT license which is likely going to make the use of your software by other projects much easier since it states explicitly what you intend with your copyright.

Many thanks for your software and for your consideration of this issue.

Regards,

Jeremiah
