#
# brew cask _stanza <stanza_name> [ --table | --yaml | --inspect | --quiet ] [ <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.
#
# Examples
#
# brew cask _stanza appcast --table

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