Hello.

vdr-sudoku included trademark'ed name.
"Sudoku" is trademark'ed. (Japan and USA)

and, Meny "sudoku" trademark find. (Try TESS)

Note: I live in Japan. not US. and I am not a lawer.

If this is "nominative use", Its no problem.


Suggests:

1. Rename software names. (NPG, SDG, etc...)

2. Contact trademark owner.

3. Remove fedora repos.


Thanks.
