[LARTC] Little script to save and restore ip rules

[Lee Lists]

Hello,

I would like to have some testers for this script which should save and 
restore ip rules and associated tables.

Thanks

#!/bin/bash

# chkconfig: 2345 85 15
# description: save and restore ip rules settings
# config: /etc/sysconfig/iprules

# source function library
