That's not much of an example; to say that it barely scratches the surface, in all its seven-paragraph glory, is to be if anything excessively kind. This is unfortunately typical of the Rails community's attitude toward these matters; you may safely assume that, were there anything remotely resembling sufficient documentation available, I would not feel the need to utter complaints such as those above -- if I have anywhere given the erroneous impression that I enjoy hacking my way through this horrible triple-canopy jungle, without so much as a sketch map, please allow me at this juncture to disabuse you of the notion!
