Change generator meta tag?

Hi,

I am a big believer in protection through obfuscation, and I like to make it a little harder for people to fully understand what technology underpins my websites.

As much as I am loving using Grav, I would like to be able to change the "generator" meta tag from "GravCMS" to something a little more obscure. Is this possible without changing the underlying source code?

Or if not, do you know which file I should update to change this?

See: https://getgrav.org/forum#!/general:generator-tag

Coolio - many thanks for that :)
