NAME

Pod::Usage::CGI - generate usage message for CGI scripts

SYNOPSIS

use CGI;
use Pod::Usage::CGI;

#Message is HTML-escaped
my $necessary = CGI::param(foo) || pod2usage(message => "you forgot >>foo<<");

#Raw message is not escaped
my $another   = CGI::param(bar) || pod2usage(raw_message => "you forgot <b>bar</b>");

DESCRIPTION

Provides pod2usage exit from CGI scripts. You may optionally supply a message. By default the message text is escaped to prevent cross-site scripting injection attacks and placed in a div container of class "message" that you can optionally format with a CSS. You can use the raw_message directive if you want to write HTML out into the page and manage your own escaping.

The module works fine under Apache::Registry but will not work in any environments where $0 is not defined.

FUNCTIONS

pod2usage(%options)

message - message (will be automatically escaped)
raw_message - message (not escaped)

DEPENDENCIES

Pod::XHtml and either Apache or CGI are loaded on demand if required
