I am currently in the process of packaging SFXR for inclusion in Ubuntu, and one of the policy requirements is prepending the appropriate license to every source file.

Not only is this a step towards including SFXR in Ubuntu, I think this will make the copyright of the files more clear.

Since the whole software is covered by the MIT license, I have attached a text file containing the header I would include.

That's a good idea. I'll make the changes in a few days unless you send patches first. Is there anything else that needs to be changed? I have only basic working knowledge of Autotools. If you write a better configure.ac and Makefile.am than I can, send them my way.

This is my first real packaging effort, so I am still learning the official package requirements. I will open new bugs for issues with the original source package, if they crop up :). I have already successfully packaged version 1.1 for personal purposes (https://launchpad.net/~ghostonline/+archive/personal/+packages), so I think the source tarball is fine. AFAIK, the only thing that might stand in our way is licensing.

Sadly, I have no developer experience with Autotools. Ik use Scons and CMake for my projects. I could whip up a build script for one of those systems, if you'd like.

I have created a patch that adds the license text to all source files and the Makefile. I am not sure which files are copyrighted to mjau/GerryJJ, but I assumed it would be sdlkit.h and Makefile. If I am mistaken, this can easily be fixed.

Patch has been applied. Thanks!
