NAME

       Plack::Runner - plackup core

SYNOPSIS

	 # Your bootstrap script
	 use Plack::Runner;
	 my $app = sub { ... };

	 my $runner = Plack::Runner->new;
	 $runner->parse_options(@ARGV);
	 $runner->run($app);

DESCRIPTION

       Plack::Runner is the core of plackup runner script. You can create your own frontend to run your application or framework, munge command
       line options and pass that to "run" method of this class.

       "run" method does exactly the same thing as the plackup script does, but one notable addition is that you can pass a PSGI application code
       reference directly to the method, rather than via ".psgi" file path or with "-e" switch. This would be useful if you want to make an
       installable PSGI application.

       Also, when "-h" or "--help" switch is passed, the usage text is automatically extracted from your own script using Pod::Usage.

NOTES

       Do not directly call this module from your ".psgi", since that makes your PSGI application unnecessarily depend on plackup and won't run
       other backends like Plack::Handler::Apache2 or mod_psgi.

       If you really want to make your ".psgi" runnable as a standalone script, you can do this:

	 my $app = sub { ... };

	 unless (caller) {
	     require Plack::Runner;
	     my $runner = Plack::Runner->new;
	     $runner->parse_options(@ARGV);
	     return $runner->run($app);
	 }

	 return $app;

       WARNING: this section used to recommend "if (__FILE__ eq $0)" but it's known to be broken since Plack 0.9971, since $0 is now always set to
       the .psgi file path even when you run it from plackup.
