#
# = Synopsis
#
# Run a +puppet+ script as a cfengine module.
#
# = Usage
#
# puppet_module [-h|--help] [-V|--version] [-d|--debug] [-v|--verbose]
# [-l|--logdest <file>]<file>
#
# = Description
#
# This is the standalone puppet execution script; use it to execute
# individual scripts that you write. If you need to execute site-wide
# scripts, use +puppetd+ and +puppetmasterd+.
#
# = Options
#
# Note that any configuration parameter that's valid in the configuration file
# is also a valid long argument. For example, 'ssldir' is a valid configuration
# parameter, so you can specify '--ssldir <directory>' as an argument.
#
# See the configuration file for the full list of acceptable parameters.
#
# debug::
# Enable full debugging.
#
# help::
# Print this help message
#
# logdest::
# Where to send messages. Choose between syslog, the console, and a log file.
# Defaults to sending messages to the console.
#
# verbose::
# Print extra information.
