# Syntax
#
# brew cask _stanza <stanza_name> [ --quiet ] [ --table | --yaml ] [ <cask_token> ... ]
#
# If no tokens are given, then data for all Casks is returned.
#
# The pseudo-stanza "artifacts" is available.
#
# On failure, a blank line is returned on the standard output.

# brew cask _stanza url --table alfred google-chrome adium vagrant
# brew cask _stanza version --table alfred google-chrome adium vagrant
# brew cask _stanza artifacts --table alfred google-chrome adium vagrant
