/dä-kyə-mən-ˈtā-shən/
n. The multiple kilograms of macerated, pounded, steamed, bleached, and pressed trees that accompany most modern software or hardware products (see also tree-killer). Hackers seldom read paper documentation and (too) often resist writing it; they prefer theirs to be terse and on-line. A common comment on this is "You can't grep dead trees".
See drool-proof paper, verbiage.
