Two constraints: 1) you can't do any of this for commercial purposes, and 2) please don't edit my actual prose, at least not without asking me first. I put all these words in a specific order for a reason.
Check out the human-readable licence or the legalese if you want the nuts and bolts. (The legalese is stuck at the back of the novels anyway). Also, be sure to set your printer at 2 pages/sheet when making a hardcopy: it saves paper, and looks a lot better too (since that's the way the files were originally formatted). Otherwise, enjoy.
