# update_robots.py

## Description

The update_robots.py script is designed to manage and update the false-robots.txt field in the group_ table of a PostgreSQL database used by Liferay, using a template file for definition.

It provides various functionalities, including updating the field based on a template file, listing current virtual hosts (vhosts), listing current false-robots.txt values and their associated hostnames, saving the current vhosts to individual files, and printing the differences between current and new false-robots.txt values. 

The scripts reads the db configurations from the portal-setup-wizard.properties of the instance.
