# See: http://angg.twu.net/e/tourism.html

# This file is full of GNUmake-isms and if you're running BSD you need
# to use gmake on it instead of the default (p?)make; also you may
# have to pass a parameter like "TCLSH=tclsh8.2" (or other version)
# because the default tclsh there may be a boring script that tells
# you to invoke tclsh with an explicit version number.

# the files in ~/TH/ if COPYING=1) before attempting to make any of
# the targets "copies", "htmls" or "$(TGZ)". The trick is that we
# first remake Makefile.auto and then call "make" a second time; only
# in that second time it will include the Makefile.auto, that will
# then be up-to-date.
