NAME
   CGI::Application::Emulate::PSGI - a legacy-code-friendly PSGI adapter
   for CGI::Application

SYNOPSIS
   Create a PSGI application from a CGI::Application project:

       # if using CGI::Application
       my $psgi_app = CGI::Application::Emulate::PSGI->handler(sub {
           my $webapp = WebApp->new();
           $webapp->run();
       });

       # if using CGI::Application::Dispatch
       my $psgi_app = CGI::Application::Emulate::PSGI->handler(sub {
           WebApp::Dispatch->dispatch();
       });

   See plackup for options for running a PSGI application.

DESCRIPTION
   CGI::Application::Emulate::PSGI allows a project based on
   CGI::Application to run as a PSGI application. Differences from
   CGI::Application::PSGI are:

   uses CGI.pm directly instead of CGI::PSGI
       CGI::Application::PSGI (that uses CGI::PSGI) does not support
       programs calling CGI.pm in func-style (like CGI::virtual_host()).
       CGI::Application::Emulate::PSGI sets up environment variables so
       that code using CGI.pm will work. Both approaches explictly use
       CGI.pm as the query object.

   compatible with CGI::Application::Dispatch
       The interface of CGI::Application::Emulate::PSGI is different from
       CGI::Application::PSGI, and is compatible with
       CGI::Application::Dispatch.

   headers are parsed and re-generated.
       This difference is in favor of CGI::Application::PSGI, which more
       directly generates the HTTP headers in PSGI format. This module
       requires additional processing: First CGI::Application builds the
       full response including the headers and body, then we parse the
       final result back into the header and body format called for by the
       PSGI spec.
