Addondomain creation variable

[shijilts]

Hello,

I am a server owner and I want to write a script in perl that runs in the server such that whenever a user create a new addon domain or subdomain from his cpanel I should be able to write it to a file with the following details.

subdomain name
addon domain name
user who created the addon domain
document root of the new addon domain

Someone please point out the easiest way by which I can pass the variables to my perl script.

Thanks
Shijil
