=head1 NAME

CGI::Pretty - module to produce nicely formatted HTML code

=head1 CGI::Pretty IS DEPRECATED

It will be removed from the CGI distribution in a future release, so you
should no longer use it and remove it from any code that currently uses it.

For now it has been reduced to a shell to prevent your code breaking, but
the "pretty" functions will no longer output "pretty" HTML.

=head1 Alternatives

L<HTML::HTML5::Parser> + L<HTML::HTML5::Writer> + L<XML::LibXML::PrettyPrint>:

    print HTML::HTML5::Writer->new(
        start_tags => 'force',
        end_tags   => 'force',
    )->document(
        XML::LibXML::PrettyPrint->new_for_html( indent_string => "\t" )
        ->pretty_print(
            HTML::HTML5::Parser->new->parse_string( $html_string )
        )
    );

L<Marpa::R2::HTML> (see the html_fmt script for examples)
