=head1 NAME
Plack - PSGI reference implementation and utilities
=head1 DESCRIPTION
Plack is a set of PSGI reference server implementations and helper
utilities for Web application frameworks, exactly like Ruby's Rack.
See L<PSGI> for the PSGI specification.
=head1 MODULES AND UTILITIES
=head2 Plack::Server
L<Plack::Server> is a namespace for PSGI server implementations. We
have Standalone, CGI, FCGI, Apache, AnyEvent, Coro, Danga::Socket and
many server environments that you can run PSGI applications on.
See L<Plack::Server> how to write your own server implementation.
=head2 Plack::Loader
L<Plack::Loader> is a loader to load one of Plack::Server backends and
run PSGI application code reference with it.
=head2 Plack::Util
L<Plack::Util> contains a lot of utility functions for server
implementors as well as middleware authors.
=head2 .psgi files
PSGI application is a code reference but it's not easy to pass code
reference in the command line or configuration files, so Plack uses a
convention that you need a file named C<app.psgi> or alike, which
would be loaded (via perl's core function C<do>) to return the PSGI
application code reference. See eg/dot-psgi directory for the example
C<.psgi> files.
=head2 plackup
L<plackup> is a command line launcher to run PSGI applications from
command line using L<Plack::Loader> to load PSGI backends. It can be
used to run standalone servers and FastCGI daemon processes. Other
server backends like Apache2 needs a separate configuration but
C<.psgi> application file can still be the same.
=head2 Plack::Middleware
PSGI middleware is a PSGI application that wraps existent PSGI
application and plays both side of application and servers. From the
servers the wrapped code reference still looks like and behaves
exactly the same as PSGI applications.
L<Plack::Middleware> gives you an easy way to wrap PSGI applications
with a clean API, and compatibility with L<Plack::Builder> DSL.
=head2 Plack::Builder
L<Plack::Builder> gives you a DSL that you can add "Middleware", in
C<.psgi> files to wrap existent PSGI applications.
=head2 Plack::Request, Plack::Response
L<Plack::Request> gives you a nice wrapper API around PSGI C<$env>
hash to get headers, cookies and query parameters much like
L<Apache::Request> in mod_perl.
L<Plack::Response> does the same to construct the response array
reference.
=head2 Plack::Test
L<Plack::Test> is an unified interface to test your PSGI application
using standard L<HTTP::Request> and L<HTTP::Response> pair with simple
callbacks.
=head2 Plack::Test::Suite
L<Plack::Test::Suite> is a test suite to test a new PSGI server backend.
