How to run a cleanup function on control-c?

[comicsads]

I would like to run a target/function when another target gets closed using ctrl-c. The reason for this is I'm creating a webserver using go, and have a mage target to build an executable and run it, and the only way to close it is by using ctrl-c. I would like to be able to run the target Cleanup() after hitting ctrl-c.
Is there anyway to do this? Is this what context.Context() is for?
Thanks in advance!

Hmm yeah, that's a feature I intended to implement with the context, but currently it's not implemented. What should happen is that ctrl-c should cancel the context and then exit after a short wait.
