 * A file in the current working directory, _eg_: `my-modfied-google-chrome.rb`. Note that matching Tapped Cask tokens will be preferred over this form when there is a conflict. To force the use of a Cask file in the current directory, specify a pathname with slashes, _eg_: `./google-chrome.rb`.

 If you are developing a subcommand, you can force `brew cask` to dispatch a specific file by giving a fully-qualified path to the file containing the subcommand, like this:
 
 ```bash
-$ brew cask /usr/local/Cellar/brew-cask/0.37.0/rubylib/hbc/cli/info.rb google-chrome
+$ brew cask /usr/local/Library/Taps/caskroom/homebrew-cask/lib/hbc/cli/info.rb google-chrome
 ```
 
 This form can also be combined with a specific Ruby interpreter as above.
