def help
    "\npuppet-device(8) -- \#{summary}\n========\n\nSYNOPSIS\n--------\nRetrieves catalogs from the Puppet master and applies them to remote devices.\n\nThis subcommand can be run manually; or periodically using cron,\na scheduled task, or a similar tool.\n\n\nUSAGE\n-----\npuppet device [-h|--help] [-v|--verbose] [-d|--debug]\n[-l|--logdest syslog|<file>|console] [--detailed-exitcodes]\n[--deviceconfig <file>] [-w|--waitforcert <seconds>]\n[--libdir <directory>]\n[-a|--apply <file>] [-f|--facts] [-r|--resource <type> [name]]\n[-t|--target <device>] [--user=<user>] [-V|--version]\n\n\nDESCRIPTION\n-----------\nDevices require a proxy Puppet agent to request certificates, collect facts,\nretrieve and apply catalogs, and store reports.\n\n\nUSAGE NOTES\n-----------\nDevices managed by the puppet-device subcommand on a Puppet agent are\nconfigured in device.conf, which is located at $confdir/device.conf by default,\nand is configurable with the $deviceconfig setting.\n\nThe device.conf file is an INI-like file, with one section per device:\n\n[<DEVICE_CERTNAME>]\ntype <TYPE>\nurl <URL>\ndebug\n\nThe section name specifies the certname of the device.\n\nThe values for the type and url properties are specific to each type of device.\n\nThe optional debug property specifies transport-level debugging,\nand is limited to telnet and ssh transports.\n\nSee https://puppet.com/docs/puppet/latest/config_file_device.html for details.\n\n\nOPTIONS\n-------\nNote that any setting that's valid in the configuration file is also a valid\nlong argument. For example, 'server' is a valid configuration parameter, so\nyou can specify '--server <servername>' as an argument.\n\n* --help, -h:\nPrint this help message\n\n* --verbose, -v:\nTurn on verbose reporting.\n\n* --debug, -d:\nEnable full debugging.\n\n* --logdest, -l:\nWhere to send log messages. Choose between 'syslog' (the POSIX syslog\nservice), 'console', or the path to a log file. If debugging or verbosity is\nenabled, this defaults to 'console'. Otherwise, it defaults to 'syslog'.\n\nA path ending with '.json' will receive structured output in JSON format. The\nlog file will not have an ending ']' automatically written to it due to the\nappending nature of logging. It must be appended manually to make the content\nvalid JSON.\n\n* --detailed-exitcodes:\nProvide transaction information via exit codes. If this is enabled, an exit\ncode of '1' means at least one device had a compile failure, an exit code of\n'2' means at least one device had resource changes, and an exit code of '4'\nmeans at least one device had resource failures. Exit codes of '3', '5', '6',\nor '7' means that a bitwise combination of the preceding exit codes happened.\n\n* --deviceconfig:\nPath to the device config file for puppet device.\nDefault: $confdir/device.conf\n\n* --waitforcert, -w:\nThis option only matters for targets that do not yet have certificates\nand it is enabled by default, with a value of 120 (seconds).  This causes\n+puppet device+ to poll the server every 2 minutes and ask it to sign a\ncertificate request.  This is useful for the initial setup of a target.\nYou can turn off waiting for certificates by specifying a time of 0.\n\n* --libdir:\nOverride the per-device libdir with a local directory. Specifying a libdir also\ndisables pluginsync. This is useful for testing.\n\nA path ending with '.jsonl' will receive structured output in JSON Lines\nformat.\n\n* --apply:\nApply a manifest against a remote target. Target must be specified.\n\n* --facts:\nDisplays the facts of a remote target. Target must be specified.\n\n* --resource:\nDisplays a resource state as Puppet code, roughly equivalent to\n`puppet resource`.  Can be filterd by title. Requires --target be specified.\n\n* --target:\nTarget a specific device/certificate in the device.conf. Doing so will perform a\ndevice run against only that device/certificate.\n\n* --to_yaml:\nOutput found resources in yaml format, suitable to use with Hiera and\ncreate_resources.\n\n* --user:\nThe user to run as.\n\n\nEXAMPLE\n-------\n$ puppet device --target remotehost --verbose\n\nAUTHOR\n------\nBrice Figureau\n\n\nCOPYRIGHT\n---------\nCopyright (c) 2011-2018 Puppet Inc., LLC\nLicensed under the Apache 2.0 License\n"
