=head1 NAME
HTTP::Server::Simple::PSGI - PSGI handler for HTTP::Server::Simple
=head1 SYNOPSIS
use HTTP::Server::Simple::PSGI;
my $server = HTTP::Server::Simple::PSGI->new($port);
$server->host($host);
$server->app($app);
$server->run;
=head1 DESCRIPTION
HTTP::Server::Simple::PSGI is a HTTP::Server::Simple based HTTP server
that can run PSGI applications. This module only depends on
L<HTTP::Server::Simple>, which itself doesn't depend on any non-core
modules so it's best to be used as an embedded web server.
