+HTML::Scrubber - Perl extension for scrubbing/sanitizing html
+
+=head1 VERSION
+
+version 0.15
+
+=head1 SYNOPSIS
+
+    use HTML::Scrubber;
+
+    my $scrubber = HTML::Scrubber->new( allow => [ qw[ p b i u hr br ] ] );
+    print $scrubber->scrub('<p><b>bold</b> <em>missing</em></p>');
+    # output is: <p><b>bold</b> </p>
+
+    # more complex input
+    my $html = q[
+    <style type="text/css"> BAD { background: #666; color: #666;} </style>
+    <script language="javascript"> alert("Hello, I am EVIL!");    </script>
+    <HR>
+        a   => <a href=1>link </a>
+        br  => <br>
+        b   => <B> bold </B>
+        u   => <U> UNDERLINE </U>
+    ];
+
+    print $scrubber->scrub($html);
+
+    $scrubber->deny( qw[ p b i u hr br ] );
+
+    print $scrubber->scrub($html);
+
+=head1 DESCRIPTION
+
+If you want to "scrub" or "sanitize" html input in a reliable and flexible
+fashion, then this module is for you.
+
+I wasn't satisfied with HTML::Sanitizer because it is based on
+HTML::TreeBuilder, so I thought I'd write something similar that works directly
+with HTML::Parser.
+
+=head1 METHODS
+
+First a note on documentation: just study the L<EXAMPLE|"EXAMPLE"> below. It's
+all the documentation you could need
+
+Also, be sure to read all the comments as well as L<How does it work?|"How does
+it work?">.
+
+If you're new to perl, good luck to you.
+
+=head2 comment
+
+    warn "comments are  ", $p->comment ? 'allowed' : 'not allowed';
+    $p->comment(0);  # off by default
+
+=head2 process
+
+    warn "process instructions are  ", $p->process ? 'allowed' : 'not allowed';
+    $p->process(0);  # off by default
+
+=head2 script
+
+    warn "script tags (and everything in between) are supressed"
+        if $p->script;      # off by default
+    $p->script( 0 || 1 );
+

+=for comment _scrub
+
+I<default> handler, does the scrubbing if we're returning a giant string. Now
+calls _scrub_str and appends that to the output string.
+
+=head1 How does it work?
+
+When a tag is encountered, HTML::Scrubber allows/denies the tag using the
+explicit rule if one exists.
+
+If no explicit rule exists, Scrubber applies the default rule.
+
+If an explicit rule exists, but it's a simple rule(1), the default attribute
+rule is applied.
+

+
+If you have Test::Inline (and you've installed HTML::Scrubber), try
+
+    pod2test Scrubber.pm >scrubber.t
+    perl scrubber.t
+
+=head1 SEE ALSO
+
+L<HTML::Parser>, L<Test::Inline>.
+
+The C<HTML::Sanitizer> module is no longer available on CPAN.
+
+=head1 VERSION REQUIREMENTS
+
+As of version 0.14 I have added a perl minimum version requirement of 5.8. This
+is basically due to failures on the smokers perl 5.6 installations - which
+appears to be down to installation mechanisms and requirements.
+
+Since I don't want to spend the time supporting a version that is so old (and
+may not work for reasons on UTF support etc), I have added a C<use 5.008;> to
+the main module.
+
+If this is problematic I am very willing to accept patches to fix this up,
+although I do not personally see a good reason to support a release that has
+been obsolete for 13 years.
+
+=head1 CONTRIBUTING
+
+If you want to contribute to the development of this module, the code is on
+L<GitHub|http://github.com/nigelm/html-scrubber>. You'll need a perl
+environment with L<Dist::Zilla>, and if you're just getting started, there's
+some documentation on using Vagrant and Perlbrew
+L<here|http://mrcaron.github.io/2015/03/06/Perl-CPAN-Pull-Request.html>.
+
+There is now a C<.perltidyrc> and a <.tidyallrc> file within the respository
+for the standard perltidy settings used - I will apply these before new
+releases.  Please do not let formatting prevent you from sending in patches etc
+- this can be sorted out as part of the release process.  Info on C<tidyall>
+can be found at
+L<https://metacpan.org/pod/distribution/Code-TidyAll/bin/tidyall>.
+
+=head1 INSTALLATION
+
+See perlmodinstall for information and options on installing Perl modules.

+
+You can make new bug reports, and view existing ones, through the
+web interface at L<http://rt.cpan.org/Public/Dist/Display.html?Name=HTML-Scrubber>.

+Archive Network (CPAN). Visit L<http://www.perl.com/CPAN/> to find a CPAN
