hey now, let's both of you calm down. kovid, i think netslut has made it clear he appreciates the usefulness of calibre and in fact he uses it himself. no-one is questioning that. if he wants to write his own indexing tool because he has different priority (and lots of time on his hands), i would think that would be a good thing. and as igorsk has said, a little competition can be a good thing. presumably he has specific needs which are not met by calibre. netslut's app might turn out to be complementary to calibre, or completely different. either way there's no reason he shouldn't try it out. let's try not to let this get personal, okay ?
both of you. no-one is in the wrong here and there's no reason for tempers to flare up.
now shake hands, go back to your corners, both of you, and come out coding ! and preferably with a smile on your face !
edit : and what taylor said is quite valid as well. thanks taylor.
