Hi, I don't see a need for xsane to have this clickthrough display of the GPL at all. As you are probably aware, at least half of Debian is GPL-licensed, and luckily not each of such programs asks the user to explicitly confirm that.
The convention in Debian is that licence information is stored in debian/copyright, so interested users will already know where to find it. I see no apparent need for xsane to require licence confirmation while nearly no other program under the same licence requires this. I would appreciate it if this question could be disabled in (Debian's) xsane. Thanks, Thijs
