# File		: syncdir.sh
# Version	: 1.1
# Date		: 2001-Jan-22
# 
# Description	: Uses rsync to sync a directory tree while ignoring
#		  stuff in env var EXCLIST
#
# Usage		: syncdir <source> <dest>
#
# Revision History:
#  2007-Jan-22	1.1 Default RSYNC_RSH set to ssh, override default
#		    rsync behaviour of "if not set, use rsh"
#  2004-Jul-08	1.0 Created
#
# Input		: src,  source      dir in rsync format
#		  dest, destination  "              "
#		  EXCLIST, env var contains files/dirs to exclude (optional)
#
# Output	: Generates a log file set with LOGFILE below
#
# Requires	:
#
# Notes		: rsync can use whatever method you like to connect.
#		  ssh with keys is very transparent.  setting the env var
#		  RSYNC_RSH=ssh tells rsync to use ssh as its transport
#		  mechanism
