/******************************************************************************************************
*
* Written by Tim Price 24/11/2016
*
* The purpose of this script is to take a juniper config and convert it to set commands.
* There was a business need to audit thbe correctness of Juniper configs and the process of logging
* into each Juniper device and dumping the configs in set format was too burdensome on both the Juniper
* devices in question but also extended the execution time of the audit scripts by some minutes.
*
* Usage example: `cat juniper-config.txt | juniper-config-to-set.php`
*
