My current use case is to find where the
Cask executable is (it can be installed in at least two places, and there's an issue open about this).
I need to require cask this way:
(require 'cask "~/.cask/cask.el")
But I need to find the correct path to that
cask.el, and as far as I know, the easiest way to do that is through locating the executable.
How can I do this?
