# findDocWords.tcl --
#
# This script attempts to find all non-dictionary words in the Tcl or Tk
# documentation tree. It handles the fairly common compoundWord trick our
# docs use, and isn't confused by nroff formatting directives, so it isn't
# just a standard spell check.
#
# Arguments:
# 1: Directory to look for man source files in.
# 2: Path to a plain text dictionary. Try /usr/share/dict/words on Linux.
