Hi,
I'm currently packaging tilem for Fedora. The review of tilem turned up the fact that two of the source files have an incorrect FSF address in their license headers, specifically gui/skinops.c and gui/skinops.h:
https://sourceforge.net/p/tilem/code/HEAD/tree/trunk/gui/skinops.h
https://sourceforge.net/p/tilem/code/HEAD/tree/trunk/gui/skinops.c
The GPL header here lists the address as "59 Temple Place, Suite 330, Boston, MA 02111-1307 USA"; according to https://www.fsf.org/about/contact/ though it's currently::
Free Software Foundation
51 Franklin Street, Fifth Floor
Boston, MA 02110-1335
USA
First, thank you for the report and for your effort in packaging tilem2 :)
I fixed it in the latest commit.
Best regards.
Thibault
