My proposal/idea would be te place it in a sane-tools package. This would be a new package with for the time being only the unpaper program. Also if there are other tools related to scanners or webcams the have a place to be kept. For example the lprof package see: gkall.hobby.nl/sane-lprof/sane-lprof.html And maybe a place to keep the icc profiles from scanners? Other packages? In this way also the package can maybe be used as a plug-in for some scanner frontend programs? This is the first email about this proposal on the SANE mailinglist so if anybody has comments/ideas?. -- -------- m.vr.gr. Gerard Klaver
