Hi, your acme code dmsc.asm is used in xscreensaver by Jamie Zawinski.
Apparently there have been issues filed before at very Freedom oriented distributions that the file is not clearly licensed and the source code is not shipped with it. E.g. at https://labs.parabola.nu/issues/131 . This has boiled up to Debian now at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=876087 and I think the obvious thing is to ask you: Could you please release this file under a DFSG compatible license (https://www.debian.org/legal/licenses/) and provide the source e.g. as a comment to the bug report and/or via email to Jamie (CC)? Thank you for your consideration! Best regards, Daniel
