How do we verify contracts?

Question from Discord:

Hello!
anyone using the truffle-flattened library for the generation of files for later contract verification?
I am looking for a way to save the content in a file instead of printing in console, do you know how to do it?

There's a great plugin here that should take care of it: https://github.com/rkalis/truffle-plugin-verify
