-# NAME
-
-yahns-rackup - a rackup-like command to launch yahns
-
-# SYNOPSIS
-
-yahns-rackup [-E RACK_ENV] [-O worker_threads=NUM] [RACKUP_FILE]
-
-# DESCRIPTION
-
-A rackup(1)-like command to launch Rack applications using yahns.
-It is expected to start in your application root (APP_ROOT).
-
-# RACKUP FILE
-
-This defaults to \"config.ru\" in APP_ROOT.  It should be the same
-file used by rackup(1) and other Rack launchers, it uses the
-*Rack::Builder* DSL.
-
-# YAHNS OPTIONS
--O client_timeout=SECONDS
-:   Defines the timeout expiring idle connections.
-
-    Increase this if your application takes longer to run than the
-    default timeout.  Lower this if you run out of FDs.
-
-    Default: 15 (seconds)
-
--O listen=ADDRESS[,ADDRESS...]
-:   Listens on a given ADDRESS.  ADDRESS may be in the form of
-    HOST:PORT or PATH, HOST:PORT is taken to mean a TCP socket
-    and PATH is meant to be a path to a UNIX domain socket.
-    Defaults to "0.0.0.0:9292" (all addresses on TCP port 9292).
-    Multiple addresses may be separated with commas.
-
--O stderr_path=PATHNAME
-:   Allow redirecting $stderr to a given path.  Unlike doing this from
-    the shell, this allows the yahns process to know the path its
-    writing to and rotate the file if it is used for logging.  The
-    file will be opened with the O_APPEND flag and writes
-    synchronized to the kernel (but not necessarily to _disk_) so
-    multiple processes can safely append to it.
-
-    If you are daemonizing and using the default logger, it is important
-    to specify this as errors will otherwise be lost to /dev/null.
-    Some applications/libraries may also triggering warnings that go to
-    stderr, and they will end up here.
-
-    Default: /dev/null if daemonized, controlling terminal if not
-
--O stdout_path=PATH
-:   Same as stderr_path, except for $stdout.  Not many applications
-    write to $stdout, but any that do will have their output written here.
-    It is safe to point this to the same location a stderr_path.
-    Like stderr_path, this defaults to /dev/null when daemonized.
-
-    Default: /dev/null if daemonized, controlling terminal if not
-
--O worker_threads=INTEGER
-:   This controls the number of threads for application processing.
-    Each queue has its own thread pool.  Increase this number if your
-    applications are able to use more threads effectively or if either
-    (or both) input/output buffering are disabled.  Lower this number if
-    you do not need multi-thread concurrency at all.
-
-    Default: 7
-
-# RACKUP OPTIONS
--D, \--daemonize
-:   Run daemonized in the background.  The process is detached from
-    the controlling terminal and stdin is redirected to /dev/null.
-    Unless specified via stderr_path and stdout_path, stderr and stdout will
-    also be redirected to "/dev/null".
-
--E, \--env RACK_ENV
-:   Run under the given RACK_ENV.  See the RACK ENVIRONMENT section
-    for more details.
-
--o, \--host HOST
-:   Listen on a TCP socket belonging to HOST, default is
-    "0.0.0.0" (all addresses).
-    If specified multiple times on the command-line, only the
-    last-specified value takes effect.
-    This option only exists for compatibility with the rackup(1) command,
-    use of "-l"/"\--listen" switch is recommended instead.
-
--p, \--port PORT
-:   Listen on the specified TCP PORT, default is 9292.
-    If specified multiple times on the command-line, only the last-specified
-    value takes effect.
-    This option only exists for compatibility with the rackup(1) command,
-    use of "-l"/"\--listen" switch is recommended instead.
-
-# RUBY OPTIONS
--e, \--eval LINE
-:   Evaluate a LINE of Ruby code.  This evaluation happens
-    immediately as the command-line is being parsed.
-
--d, \--debug
-:   Turn on debug mode, the $DEBUG variable is set to true.
-
--w, \--warn
-:   Turn on verbose warnings, the $VERBOSE variable is set to true.
-
--I, \--include PATH
-:   specify $LOAD_PATH.  PATH will be prepended to $LOAD_PATH.
-    The \':\' character may be used to delimit multiple directories.
-    This directive may be used more than once.  Modifications to
-    $LOAD_PATH take place immediately and in the order they were
-    specified on the command-line.
-
--r, \--require LIBRARY
-:   require a specified LIBRARY before executing the application.  The
-    \"require\" statement will be executed immediately and in the order
-    they were specified on the command-line.
