<<-HELP
puppet-faces(8) -- List available Faces and actions
========
SYNOPSIS
--------
Lists the available subcommands (with applicable terminuses and/or actions)
provided by the Puppet Faces API. This information is automatically read
from the Puppet code present on the system. By default, the output includes
all terminuses and actions.
USAGE
-----
puppet faces [-d|--debug] [-v|--verbose] [actions|terminuses]
OPTIONS
-------
Note that any configuration option valid in the configuration file is also
a valid long argument. See the configuration file documentation at
http://docs.puppetlabs.com/references/stable/configuration.html for the
full list of acceptable parameters. A commented list of all
configuration options can also be generated by running puppet agent with
'--genconfig'.
* --verbose:
Sets the log level to "info." This option has no tangible effect at the time
of this writing.
* --debug:
Sets the log level to "debug." This option has no tangible effect at the time
of this writing.
