	# Sample .bashrc for SuSE Linux
	# Copyright (c) SuSE GmbH Nuernberg

	# There are 3 different types of shells in bash: the login shell, normal shell
	# and interactive shell. Login shells read ~/.profile and interactive shells
	# read ~/.bashrc; in our setup, /etc/profile sources ~/.bashrc - thus all
	# settings made here will also take effect in a login shell.
	#
	# NOTE: It is recommended to make language settings in ~/.profile rather than
	# here, since multilingual X sessions would not work properly if LANG is over-
