# = Synopsis
#
# The central puppet server.  Functions as a certificate authority by default.
#
# = Usage
#
#   puppetmasterd [-D|--daemonize|--no-daemonize] [-d|--debug] [-h|--help]
#       [-l|--logdest <file>|console|syslog] [--nobucket] [--nonodes]
#       [-v|--verbose] [-V|--version]
#
# = Description
#
# This is the puppet central daemon.
#
# = 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 documentation at
# http://reductivelabs.com/projects/puppet/reference/configref.html for
# the full list of acceptable parameters. A commented list of all
# configuration options can also be generated by running puppetmasterdd with
# '--genconfig'.
#
# daemonize::
#   Send the process into the background.  This is the default.
#
# no-daemonize::
#   Do not send the process into the background.
#
# 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 syslog, or the console
#   if debugging or verbosity is enabled.
#
# nobucket::
#   Do not function as a file bucket.
#
# nonodes::
#   Do not use individual node designations; each node will receive the result
#   of evaluating the entire configuration.
#
# noreports::
#   Do not start the reports server.
#
# verbose::
#   Enable verbosity.
#
# version::
#   Print the puppet version number and exit.
