       Plack::Runner - plackup core


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

         my $runner = Plack::Runner->new;


       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.


       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;
             exit 0;

         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.
