Spare Homebrew casks

This repository serves as a tap for a handful of programs I use that don't (yet)
have Homebrew-official casks. They may be useful to others, or they may not.

How do I install these formulae?

brew install bsoyka/extras/<formula>

Or brew tap bsoyka/extras and then brew install <formula>.

Or, in a brew bundle Brewfile:

tap "bsoyka/extras"
brew "<formula>"
