accepts a single argument, which is a relative path to a pkg inside the extracted Cask; homebrew-cask will attempt to install this pkg after the Cask is extracted via `installer` because of the many different ways uninstallers work, this has several features: - `:script`: a script in the Cask which serves as an uninstaller (e.g. Vagrant, VirtualBox), uses `:args`, and `:input` keys to interact with said script - `:pkgutil`: a regexp which captures all package_ids installed by this cask; homebrew-cask will list all files installed under these ids and remove them - `:launchctl`: a list of bundle_ids for services that should be removed by homebrew-cask - `:files`: a fallback list of files to manually remove; helps when uninstallers miss something refs #661
