Re: Python Wrapper for wireguard-tools

[Ryan Whelan <rcwhelan@gmail.com>]

At this point, it's very old and not in use, but I once worked on a
project that would wrap the `wg` command in python.

If helpful, I posted it here:
https://gist.github.com/rwhelan/f46d1f6f07df71f1bd1786eda447b97f

I don't think its feature complete as it was only used internally for
a project that took another direction. But in case it's helpful...
