I'm hoping someone could answer this for me. How do you trust the applications that `brew cask` installs?

What is preventing `brew cask install firefox` from installing something malicious? When I download an application manually, I trust the site I'm on by virtue of being there and being savvy enough to know it's a legitimate site. But when you script it, you lose the ability to gauge see for yourself what you're downloading.

I realize I could probably do: `brew cask info firefox`, find the ruby file it points to (https://github.com/caskroom/homebrew-cask/commits/master/Cas...), open that up, verify the link is trustworthy.. but I don't want to do that for every installation. And if it's valid now, what's to prevent it from changing in the future?

How do you guys justify using cask?
