def help
  "\npuppet-apply(8) -- Apply Puppet manifests locally\n========\n\nSYNOPSIS\n--------\nApplies a standalone Puppet manifest to the local system.\n\n\nUSAGE\n-----\npuppet apply [-h|--help] [-V|--version] [-d|--debug] [-v|--verbose]\n[-e|--execute] [--detailed-exitcodes] [-l|--logdest <file>]\n[--apply <catalog>] <file>\n\n\nDESCRIPTION\n-----------\nThis is the standalone puppet execution tool; use it to apply\nindividual manifests.\n\nWhen provided with a modulepath, via command line or config file, puppet\napply can effectively mimic the catalog that would be served by puppet\nmaster with access to the same modules, although there are some subtle\ndifferences. When combined with scheduling and an automated system for\npushing manifests, this can be used to implement a serverless Puppet\nsite.\n\nMost users should use 'puppet agent' and 'puppet master' for site-wide\nmanifests.\n\n\nOPTIONS\n-------\nNote that any configuration parameter that's valid in the configuration\nfile is also a valid long argument. For example, 'modulepath' is a\nvalid configuration parameter, so you can specify '--tags <class>,<tag>'\nas an argument.\n\nSee the configuration file documentation at\nhttp://docs.puppetlabs.com/references/stable/configuration.html for the\nfull list of acceptable parameters. A commented list of all\nconfiguration options can also be generated by running puppet with\n'--genconfig'.\n\n* --debug:\nEnable full debugging.\n\n* --detailed-exitcodes:\nProvide transaction information via exit codes. If this is enabled, an exit\ncode of '2' means there were changes, an exit code of '4' means there were\nfailures during the transaction, and an exit code of '6' means there were both\nchanges and failures.\n\n* --help:\nPrint this help message\n\n* --loadclasses:\nLoad any stored classes. 'puppet agent' caches configured classes\n(usually at /etc/puppet/classes.txt), and setting this option causes\nall of those classes to be set in your puppet manifest.\n\n* --logdest:\nWhere to send messages. Choose between syslog, the console, and a log\nfile. Defaults to sending messages to the console.\n\n* --execute:\nExecute a specific piece of Puppet code\n\n* --verbose:\nPrint extra information.\n\n* --apply:\nApply a JSON catalog (such as one generated with 'puppet master --compile'). You can\neither specify a JSON file or pipe in JSON from standard input.\n\n\nEXAMPLE\n-------\n  $ puppet apply -l /tmp/manifest.log manifest.pp\n  $ puppet apply --modulepath=/root/dev/modules -e \"include ntpd::server\"\n\n\nAUTHOR\n------\nLuke Kanies\n\n\nCOPYRIGHT\n---------\nCopyright (c) 2011 Puppet Labs, LLC Licensed under the Apache 2.0 License\n\n  HELP\nend\n"
