"""%prog <server>[.<config>] [<server>[.<config>] ...] <command> [options]
where:
<server> is the name of a swift service e.g. proxy-server.
The '-server' part of the name may be omitted.
'all', 'main' and 'rest' are reserved words that represent a
group of services.
all: Expands to all swift daemons.
main: Expands to main swift daemons.
(proxy, container, account, object)
rest: Expands to all remaining background daemons (beyond
"main").
(updater, replicator, auditor, etc)
<config> is an explicit configuration filename without the
.conf extension. If <config> is specified then <server> should
refer to a directory containing the configuration file, e.g.:
swift-init object.1 start
will start an object-server using the configuration file
/etc/swift/object-server/1.conf
<command> is a command from the list below.
Commands:
