       plackup - Run PSGI application with Plack handlers

	 # read	your app from app.psgi file

	 # choose .psgi	file from ARGV[0] (or with -a option)
	 plackup hello.psgi

	 # switch server implementation	with --server (or -s)
	 plackup --server HTTP::Server::Simple --port 9090 --host test.psgi

	 # use UNIX socket to run FCGI daemon
	 plackup -s FCGI --listen /tmp/fcgi.sock myapp.psgi

	 # launch FCGI external	server on port 9090
	 plackup -s FCGI --port	9090

       plackup is a command line utility to run	PSGI applications from the
       command line.

       plackup automatically figures out the environment it is run in, and
       runs your application in	that environment. FastCGI, CGI,	AnyEvent and
       others can all be detected. See Plack::Loader for the authoritative

       "plackup" assumes you have an "app.psgi"	script in your current
       directory.  The last statement of "app.psgi" should be a	code reference
       that is a PSGI application:

	 use MyApp;
	 my $application = MyApp->new;
	 my $app = sub { $application->run_psgi(@_) };

	     plackup --host --port 9090 /path/to/app.psgi

	   The first non-option	argument is used as a ".psgi" file path. You
	   can also set	this path with "-a" or "--app".	If omitted, the
	   default file	path is	"app.psgi" in the current directory.

       -a, --app
	   Specifies the full path to a	".psgi"	script.	You may	alternately
	   provide this	path as	the first argument to "plackup".

       -e  Evaluates the given perl code as a PSGI app,	much like perl's "-e"

	     plackup -e	'sub { my $env = shift;	return [ ... ] }'

	   It is also handy when you want to run a custom application like

	     plackup -MPlack::App::File	-e 'Plack::App::File->new(...)->to_app'

	   You can also	specify	"-e" option with ".psgi" file path to wrap the
	   application with middleware configuration from the command line.
	   You can also	use Plack::Builder DSL syntax inside "-e" code.	For

	     plackup -e	'enable	"Auth::Basic", authenticator =>	...;' myapp.psgi

	   is equivalent to the	PSGI application:

	     use Plack::Builder;
	     use Plack::Util;

	     builder {
		 enable	"Auth::Basic", authenticator =>	...;

	   Note	that when you use "-e" option to enable	middleware, plackup
	   doesn't assume the implicit "app.psgi" path.	You must either	pass
	   the path to your ".psgi" file in the	command	line arguments or load
	   the application inside "-e" after the "enable".

	     plackup				    # Runs app.psgi
	     plackup -e	'enable	"Foo"'		    # Doesn't work!
	     plackup -e	'enable	"Foo"' app.psgi	    # Works
	     plackup -e	'enable	"Foo"; sub { ... }' # Works

       -o, --host
	   Binds to a TCP interface. Defaults to undef,	which lets most	server
	   backends bind to the	any (*)	interface. This	option is only valid
	   for servers which support TCP sockets.

       -p, --port
	   Binds to a TCP port.	Defaults to 5000. This option is only valid
	   for servers which support TCP sockets.

       -s, --server, the "PLACK_SERVER"	environment variable
	   Selects a specific server implementation to run on. When provided,
	   the "-s" or "--server" flag will be preferred over the environment

	   If no option	is given, plackup will try to detect the best server
	   implementation based	on the environment variables as	well as
	   modules loaded by your application in %INC. See Plack::Loader for

       -S, --socket
	   Listens on a	UNIX domain socket path. Defaults to undef. This
	   option is only valid	for servers which support UNIX sockets.

       -l, --listen
	   Listens on one or more addresses, whether "HOST:PORT", ":PORT", or
	   "PATH" (without colons). You	may use	this option multiple times to
	   listen on multiple addresses, but the server	will decide whether it
	   supports multiple interfaces.

       -D, --daemonize
	   Makes the process run in the	background. It's up to the backend
	   server/handler implementation whether this option is	respected or

       -I  Specifies Perl library include paths, like "perl"'s -I option. You
	   may add multiple paths by using this	option multiple	times.

       -M  Loads the named modules before loading the app's code. You may load
	   multiple modules by using this option multiple times.

	   In combination with "-r" or "-R" may	not have the desired restart
	   effect when the loaded module is changed in the development
	   directory. To avoid this problem you	need to	load the module	with
	   the app code	using "-e".

       -E, --env, the "PLACK_ENV" environment variable.
	   Specifies the environment option. Setting this value	with "-E" or
	   "--env" also	writes to the "PLACK_ENV" environment variable.	This
	   allows applications or frameworks to	tell which environment setting
	   the application is running on.

	     # These two are the same
	     plackup -E	deployment
	     env PLACK_ENV=deployment plackup

	   Common values are "development", "deployment", and "test". The
	   default value is "development", which causes	"plackup" to load the
	   middleware components: AccessLog, StackTrace, and Lint unless
	   "--no-default-middleware" is	set.

	   This	prevents loading the default middleware	stack even when	Plack
	   environment (i.e. "-E" or "PLACK_ENV") is set to "development".

       -r, --reload
	   Makes plackup restart the server whenever a file in your
	   development directory changes. This option by default watches the
	   "lib" directory and the base	directory where	.psgi file is located.
	   Use "-R" to watch other directories.

	   Reloading will delay	the compilation	of your	application. Automatic
	   server detection (see "-s" above) may not behave as you expect, if
	   plackup needs to scan your application for the modules it uses.
	   Avoid problems by specifying	"-s" explicitly	when using "-r"	or

	   To avoid problems with changes to preloaded modules see
	   documentation for "-M".

       -R, --Reload
	   Makes plackup restart the server whenever a file in any of the
	   given directories changes. "-R" and "--Reload" take a comma-
	   separated list of paths:

	     plackup -R	/path/to/project/lib,/path/to/project/templates

	   To avoid problems with changes to preloaded modules see
	   documentation for "-M".

       -L, --loader
	   Specifies the server	loading	subclass that implements how to	run
	   the server.	Available options are Plack::Loader (default),
	   Restarter (automatically set	when "-r" or "-R" is used), Delayed,
	   and Shotgun.

	   See Plack::Loader::Delayed and Plack::Loader::Shotgun for more

	   Specifies the pathname of a file where the access log should	be
	   written.  By	default, in the	development environment	access logs
	   will	go to STDERR.

	   Specify the root path of your app ("SCRIPT_NAME" in PSGI env) to
	   run.	The following two commands are roughly the same.

	     plackup --path /foo app.psgi
	     plackup -e	'mount "/foo" => Plack::Util::load_psgi("app.psgi")'

       Other options that starts with "--" are passed through to the backend
       server.	See each Plack::Handler	backend's documentation	for more
       details on their	available options.
