  "\npuppet-queue(8) -- Queuing daemon for asynchronous storeconfigs\n========\n\nSYNOPSIS\n--------\nRetrieves serialized storeconfigs records from a queue and processes\nthem in order.\n\n\nUSAGE\n-----\npuppet queue [-d|--debug] [-v|--verbose]\n\n\nDESCRIPTION\n-----------\nThis application runs as a daemon and processes storeconfigs data,\nretrieving the data from a stomp server message queue and writing it to\na database.\n\nFor more information, including instructions for properly setting up\nyour puppet master and message queue, see the documentation on setting\nup asynchronous storeconfigs at:\nhttp://projects.puppetlabs.com/projects/1/wiki/Using_Stored_Configuration\n\n\nOPTIONS\n-------\nNote that any configuration parameter that's valid in the configuration\nfile is also a valid long argument. For example, 'server' is a valid\nconfiguration parameter, so you can specify '--server <servername>' as\nan 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 queue with\n'--genconfig'.\n\n* --debug:\nEnable full debugging.\n\n* --help:\nPrint this help message\n\n* --verbose:\nTurn on verbose reporting.\n\n* --version:\nPrint the puppet version number and exit.\n\n\nEXAMPLE\n-------\n  $ puppet queue\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"
