Distribute modified sdl_ttf and copyright

SDL Development
1

Dear board,

so I fiddled with the source. That was the easy part.
To be exact I modified sdl_ttf.h and sdl_ttf.c
from the SDL_ttf-2.0.11 package to suit the needs of my program.

Now I’m trying to get it into shape for publication.

What I have done so far:
At the top of sdl_ttf.h and sdl_ttf.c (first line):

Code:
Modified 2013 by Matthias Kievernagel (mkiever/at/tlink/dot/de)

In the README right after my own copyright statement:

Code:

The distribution contains modified versions of the files
SDL_ttf.h and SDL_ttf.c
from the SDL_ttf package (version 2.0.11)
which are Copyright © 1997-2012 Sam Lantinga
See COPYING_SDL_ttf for details about their license.

There is a second notice in the README about
the modified sdl_ttf files in the part with the building requisites.
Added the file COPYING from the SDL_ttf-2.0.11 package
renamed as COPYING_SDL_ttf.

Is this the correct way ? Anything I have forgotten ? Is it overdone in some way ?

Thanks in advance,
Matthias Kievernagel

Generally it depends on the amount of changes you did to the file but each
project has its own preference.
By the way did you end up publishing the code anywhere? Is there anything
that could be merged upstream?

…

The changes and possible merging have been discussed here:
SDL :: View topic - SDL_ttf: Select another charmap

And yes, I published the experiment now on github:
GitHub - mkiever/sdl_unifontview: Unicode Font Viewer for SDL

Thanks Vittorio,
