If such a thing does not exist, it should. I very much enjoy the wiki documentation, but it would be nice to have an offline copy. My father asked me about this yesterday and I told him, "I'm sure they have some form of printable reference." I cannot find it, so I think I have misspoke. He has been into electronics for more the 30 years and just can't be comfortable without a printed manual. If such a thing doesn't exist, I will write a bash script to scrape it from http://arduino.cc/en/Reference/Extended?action=print
I would just like to know if I am wasting my time recreating someone else's work.
