"""%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.
<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
