##
## This makefile will hopefully replace the old ways of
## building zangband.  Using automake is crufty, and using
## makefile.std doesn't quite cover all the nice things
## that autoconf does.
##
##
##
## Please do not edit "makefile", as it is auto-generated
## by ./configure from makefile.in  Edit makefile.in instead.
