Hi, This may be a question for upstream rather than debian, but I thought I would start here to see if anyone was aware of this issue or had dealt with it previously.
At a number of places in the source code for postgis, reference is made to the comp.graphics.algorithm FAQ [1]. As an example, see the comments at [2]. This appears to be a fairly direct lifting of text from the FAQ, a document which a Joseph O'Rouke is (claims to be?) the author of. It appears that redistribution of that document in its entirety is permitted, however nothing is said about partial extracts. This article is Copyright 2003 by Joseph O'Rourke. It may be freely redistributed in its entirety provided that this copyright notice is not removed. Joseph O'Rourke does not appear to be listed in the debian/copyright file [3]. This gives rise to two questions (unfortunately rather pedantic questions): 1) Should Joseph O'Rouke be listed in the debian/copyright file? 2) Do we (and upstream) have permission to distribute the resulting source code (as GPL or otherwise)? Hopefully this is not opening a can of worms. Thanks, Joe [1] http://www.faqs.org/faqs/graphics/algorithms-faq/ [2] https://github.com/postgis/postgis/blob/svn-trunk/liblwgeom/measures.c#L2061 [3] https://anonscm.debian.org/git/pkg-grass/postgis.git/tree/debian/copyright
