Apache Host Sync
This script is useful for web developers and administrators whom use Apache name based virtual hosts to host multiple websites on the same server and would like to have the Listen and NameVirtualHost directives automatically updated when they add or remove virtual hosts.
Even though these are usually easy to configure it can be tedious to keep these values updated on some setups where hosts are being added and removed frequently. In these setups you could just add these directives to your vhost configuration but, in the case of the Listen directive, you'll need to ensure that they do not conflict so it is more handy to have them all listed in the same place. This is why the default Apache setup breaks these out into a separate file called
ports.conf on most setups. Using this script you'll have the best of both worlds by being able to configure only the vhost definition while still having a central definition to avoid conflicts.
It works by scanning a list of configuration files
