The only thing stopping me from uploading is that the original source archive contains a 3Mb 'screendump' X image, which I suspect is there accidentally. Is that right? if it's a mistake then I'll remove it from the 'therion-0.2.17.orig.tar.gz' source tarball and build against that.
Yes, it should not be there.
And the new bac module seems to be designed to calculate blood alcohol levels after getting pissed - I can't quite see the (direct) relevance to cave drawing of this? What do I use it for? :-)
It is only an experimental funny Help feature - therefore it's placed in the Help menu. From my experience, blood alcohol level has quite important influence on number of errors made, when drawing maps with xtherion - not very idiot resistant interface :) Regards, S.
