[Pkg-fonts-devel] Interpreting "based on" statement in License block (fontforge licensing)
Hi,
While updating the copyright file of fontforge I came across some files
which has below style license header (please see at end of the mail).
Files are licensed GPL-3+ but as line "Based on example code in zguide"
followed by MIT/Expat style licensing. Looking at original code ¹ I see
there are modifications in this version so it looks like derivative work
which is relicensed as GPL-3+. Also the original licensing block is kept
to meet the MIT/Expat licensing terms.
Now my question is how do we interpret this license?.
PS: If you think I should approach debian-legal, please let me know.
