Bug#590734: simutrans: Non-free license terms

[Ansgar Burchardt]

retitle  590734 Please improve wording of simutrans/copyright.txt
severity 590734 minor
thanks

Hi,

by now Hajo has also written a comment [1] on this problem and upstream
has applied the proposed patch [2].  I don't see any remaining problem.
As this should already be the intended interpretation of the current
license, I will downgrade the severity and change the bug title
accordingly.

Regards,
Ansgar
