Hey @syke99 thanks for working on this!

I'm a bit confused by the PR though. It's not really connected to Bud in anyway. You'd need to add the -ldflags to the app command. Is this still a draft PR?

I'm also thinking we can simplify this buildinfo package quite a bit, pretty sure something like:

bud/internal/versions/versions.go

Line 4 in d243eed

var Bud = "latest"

would suffice.

Hey @matthewmueller, I'm so sorry. Yes, this was supposed to just be a draft PR for now. I was expecting to continue being able to work on it, but I've had some personal stuff come up that has been taking precedence, so I've had to step away. And you're right, that does seem like it would suffice for what I had added. Again, my apologies!!
