[erlang-questions] Reltool anyone?

We are explaining how OTP works by explaining what is going on behind the scenes. A different approach I found out worked better when teaching behaviours than diving straight into callback hell. Release handling, on the other hand, has always been the black sheep because of the lack of a unified approach. Everyone has historically  reached (potentially different) goals in different ways, often depending on what they were used to and comfortable with from previous (non Erlang) jobs. 

Buy me or Ulf a beer and we will tell you how release handling was done with the Axd301. You must have a strong stomach, as it is not for the faint of heart :-)
