i have never used it, i use dpkg whenever there is a need, but yes i have looked at it, it was cool ...
but whats wrong with it ? I think, when desaster is just a click away, its more likely to happen compared to opening a scary dark terminal (which of course you have never seen before) and typing in a command not a word of which you understand, from a place where whoever has written it is talking about scary things that you do not understand .... do you agree ?
