From d31deb3d9cc7ff7b054e08a64310f057d827a431 Mon Sep 17 00:00:00 2001
From: "Theodore A. Roth" <troth@openavr.org>
Date: Tue, 25 Feb 2003 00:57:27 +0000
Subject: [PATCH] * ChangeLog: Point reader to the CHANGELOG file. *
 Makefile.am (EXTRA_DIST): Rename avrdude.conf.sample to avrdude.conf.in. 
 Remove avrdude.conf and distclean-local rules. 	Add install-exec-local
 and backup-avrdude-conf rules. * avrdude.conf.in: 	Set default_parallel
 to "@DEFAULT_PAR_PORT@" for autoconf expansion. 	Set default_serial to
 "@DEFAULT_SER_PORT@" for autoconf expansion. * configure.ac: Add call to
 AC_CANONICAL_{BUILD,HOST,TARGET} macros. 	Set DEFAULT_PAR_PORT and
 DEFAULT_SER_PORT based on $host. 	Add copyright header. 	Define
 avrdude_version so AC_INIT and AM_INIT_AUTOMAKE are sure 	to get the
 same version.
