Turnkey OpenVPN - Add new users. It creates two OVPN files - with and without proxy and also generates the URLs to download them. Safely use for existing users - it just creates the OVPN files.

Usage: sudo $0 client_or_profile_name
This will create two ovpn files in this directory (proxy and noproxy).
You can safely run this for existing users too - to regenerate their license files.
Example of client name - divya.mahajan, pritam.kumar

This must be run as sudo.
