=head1 NAME

Pod::Elemental::Transformer::PPIHTML - convert "=begin perl" and shebang-marked blocks to XHTML

=head1 VERSION

version 0.093581


This transformer, based on L<Pod::Elemental::Transformer::SynHi>, looks for
regions like this:

  =begin perl

    my $x = 1_00_000 ** $::xyzzy;

  =end perl

...into syntax-highlighted HTML that I can't really usefully represent here.
It uses L<PPI::HTML>, so you can read more about the kind of HTML it will
produce, there.

This form is also accepted, in a verbatim paragraph:

  my $x = 1_00_000 ** $::xyzzy;

In the above example, the shebang-like line will be stripped.

The C<format_name> attribute may be supplied during the construction of the
transformer to look for a region other than C<perl>.
