Redistributing modified SFML source code -License question
« on: December 02, 2010, 06:40:18 pm »
Hello Laurent,

I am in the process of writing a library, specifically for use with SFML. For that purpose, I need to include slightly modified parts of the SFML source.
One example of this is Input.cpp, where I have only changed a few lines.

However, I still want the changes to be copyrighted and licensed under the zlib license. This is only to ensure that it will always remain free for any purpose, and I don't actually care who owns the copyright.

So what should I put at the top of the file? Would the following be OK?
Code: [Select]

I think it's ok since you say that it's based on sfml ;) .

1. The origin of this software must not be misrepresented;
2. Altered source versions must be plainly marked as such,
   and must not be misrepresented as being the original software.

SFML has a zlib-png license, one of the most permissive license ;) .
