=head1 NAME

Webinject::Gui - Gui part of Webinject

=head1 SYNOPSIS

    use Webinject::Gui;
    my $webinjectgui = Webinject::Gui->new();

=head1 DESCRIPTION

WebInject is a free tool for automated testing of web applications and web
services. It can be used to test individual system components that have HTTP
interfaces (JSP, ASP, CGI, PHP, AJAX, Servlets, HTML Forms, XML/SOAP Web
Services, REST, etc), and can be used as a test harness to create a suite of
[HTTP level] automated functional, acceptance, and regression tests. A test
harness allows you to run many test cases and collect/report your results.
WebInject offers real-time results display and may also be used for monitoring
system response times.

=head1 CONSTRUCTOR

=head2 new ( [ARGS] )

Creates an C<Webinject::Gui> object.
