                         <title>Hello World Resource</title>
                     </head>
                     <body>
                         <h1>Hello World</h1>
                     </body>
                  </html>}

DESCRIPTION

       "Web::Machine" provides a RESTful web framework modeled as a state machine. You define one
       or more resource classes. Each resource represents a single RESTful URI end point, such as
       a user, an email, etc. The resource class can also be the target for "POST" requests to
       create a new user, email, etc.

       Each resource is a state machine, and each request for a resource is handled by running
       the request through that state machine.

       "Web::Machine" is built on top of Plack, but it handles the full request and response
       cycle.

       See Web::Machine::Manual for more details on using "Web::Machine" in general, and how
       "Web::Machine" and Plack interact.

       This is a port of Webmachine <https://github.com/basho/webmachine>, actually it is much
       closer to the Ruby version <https://github.com/seancribbs/webmachine-ruby>, with a little
       bit of the JavaScript version <https://github.com/tautologistics/nodemachine> and even
       some of the Python version <https://github.com/benoitc/pywebmachine> thrown in for good
       measure.

       You can learn a bit about Web::Machine's history from the slides for my 2012 YAPC::NA talk
       <https://speakerdeck.com/stevan_little/rest-from-the-trenches>.

       To learn more about Webmachine, take a look at the links in the SEE ALSO section.

METHODS

       NOTE: This module is a Plack::Component subclass and so follows the interface set forward
       by that module.

       "new( resource => $resource_classname, ?resource_args => $arg_list, ?tracing => 1|0,
       ?streaming => 1|0, ?request_class => $request_class )"
           The constructor expects to get a $resource_classname, which it will use to load and
           create an instance of the resource class. If that class requires any additional
           arguments, they can be specified with the "resource_args" parameter. The contents of
           the "resource_args" parameter will be made available to the "init()" method of
           "Web::Machine::Resource".

           The "new" method can also take an optional "tracing" parameter which it will pass on
           to Web::Machine::FSM and an optional "streaming" parameter, which if true will run the
           request in a PSGI <http://plackperl.org/> streaming response. This can be useful if
           you need to run your content generation asynchronously.

           The optional "request_class" parameter accepts the name of a module that will be used
           as the request object. The module must be a class that inherits from Plack::Request.
           Use this if you have a subclass of Plack::Request that you would like to use in your
           Web::Machine::Resource.

       "inflate_request( $env )"
           This takes a raw PSGI $env and inflates it into a Plack::Request instance.  By default
           this also uses HTTP::Headers::ActionPack to inflate the headers of the request to be
           complex objects.

       "create_fsm"
           This will create the Web::Machine::FSM object to run. It will get passed the value of
           the "tracing" constructor parameter.

       "create_resource( $request )"
           This will create the Web::Machine::Resource instance using the class specified in the
           "resource" constructor parameter. It will pass in the $request object and call
           "new_response" on the $request object to get a Plack::Response instance.

       "finalize_response( $response )"
           Given a $response which is a Plack::Response object, this will finalize it and return
           a raw PSGI response.

       "call( $env )"
           This is the "call" method overridden from the Plack::Component superclass.

DEBUGGING

       If you set the "WM_DEBUG" environment variable to 1 we will print out information about
       the path taken through the state machine to STDERR.

       If you set "WM_DEBUG" to "diag" then debugging information will be printed using
       Test::More's "diag()" sub instead.
