.SH "NAME"
Plack::Handler::CGI \- CGI handler for Plack
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
Want to run \s-1PSGI\s0 application as a \s-1CGI\s0 script? Rename .psgi to .cgi and
change the shebang line like:
.PP
.Vb 2
\&  #!/usr/bin/env plackup
\&  # rest of the file can be the same as other .psgi file
.Ve
.PP
You can alternatively create a .cgi file that contains something like:
.PP
.Vb 4
\&  #!/usr/bin/perl
\&  use Plack::Loader;
\&  my $app = Plack::Util::load_psgi("/path/to/app.psgi");
\&  Plack::Loader\->auto\->run($app);
.Ve
.PP
This will auto-recognize the \s-1CGI\s0 environment variable to load this class.
.PP
If you really want to explicitly load the \s-1CGI\s0 handler, you can. For instance
you might do this when you want to embed a \s-1PSGI\s0 application server built into
CGI-compatible perl-based web server:
.PP
.Vb 2
\&  use Plack::Handler::CGI;
\&  Plack::Handler::CGI\->new\->run($app);
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is a handler module to run any \s-1PSGI\s0 application as a \s-1CGI\s0 script.
.SH "UTILITY METHODS"
.IX Header "UTILITY METHODS"
.SS "\fBsetup_env()\fP"

.Vb 2
\&  my $env = Plack::Handler::CGI\->setup_env();
\&  my $env = Plack::Handler::CGI\->setup_env(\e%override_env);
.Ve
.PP
Sets up the \s-1PSGI\s0 environment hash for a \s-1CGI\s0 request from \f(CW%ENV\fR> and returns it.
You can provide a hashref of key/value pairs to override the defaults if you would like.
