/*
 * The big old tree between the Obstwiese and the Kartoffelacker (world/site.c
 * plants it): it leans towards the road, and over the road runs the phone
 * line. Enrico (Go-Darmstadt) fells it the other way: a rope thrown up over a
 * branch as high as it'll go (a job for you), the notch cut on the side it
 * should fall to, a few people pulling on the rope from well out, the back
 * cut. Where it comes down depends on how many pull, how high the rope is, a
 * gust - the people's part is ai_jobs.c, the rest game_bigtree.c. Here: where
 * everything is.
