=head1 Name

Text::Markup::Pod - Pod parser for Text::Markup

=head1 Synopsis

  use Text::Markup;
  my $pod = Text::Markup->new->parse(file => 'README.pod');

=head1 Description

This is the L<Pod|perlpod> parser for L<Text::Markup>. It runs the file
through L<Pod::Simple::XHTML> and returns the result. If the Pod contains any
non-ASCII characters, the encoding must be declared either via a BOM or via
the C<=encoding> tag. Text::Markup::Pod recognizes files with the following
extensions as Pod:

=over

=item F<.pod>

=item F<.pm>

=item F<.pl>

=back

=head1 Options

You may pass an arrayref of settings to this parser which changes the output returned.  For example,
to suppress an HTML header and footer, pass:

  my $pod_fragment = Text::Markup->new->parse(
          file => 'README.pod',
          options => [
              html_header => '',
              html_footer => '',
          ]
  );

This implementation makes method calls to the L<Pod::Simple::XHTML> parser using the key as the method
name and the value as the parameter list to pass.  

See L<Pod::Simple::XHTML> and L<Pod::Simple> for the full list of options and inherited options
which can be manipulated.
