/* Read KConfig() entries - for use in shell scripts.
 * (c) 2001 Red Hat, Inc.
 * Programmed by Bernhard Rosenkraenzer <bero@redhat.com>
 *
 * If --type is specified as bool, the return value is 0 if the value
 * is set, 1 if it isn't set. There is no output.
 *
 * If --type is specified as num, the return value matches the value
 * of the key. There is no output.
 *
 * If --type is not set, the value of the key is simply printed to stdout.
 *
 * Usage examples:
 *	if kreadconfig --group KDE --key macStyle --type bool; then
 *		echo "We're using Mac-Style menus."
 *	else
 *		echo "We're using normal menus."
 *	fi
 *
 *	TRASH=`kreadconfig --group Paths --key Trash`
 *	if test -n "$TRASH"; then
 *		mv someFile "$TRASH"
 *	else
 *		rm someFile
 *	fi
