# This is the tenth and last part of the Hack 1.0.2 distribution.
# Unpack it (the 9 other files must already have been unpacked),
# edit Makefile in case your termcap library is not found with -ltermlib
# (perhaps with -ltermcap ?), edit config.h to reflect your local
# situation, and run Makefile.

# This is a shell archive.  Remove anything before this line, then
# unpack it by saving it in a file and typing "sh file".  (Files
# unpacked will be owned by you and have default permissions.)
#
# This archive contains:
# alloc.c rnd.c makedefs.c hack.c hack.wizard.c
# and an edit script updating previous parts of the distribution.
