=head1 NAME

App::Pod2Epub - Convert Pod to an ePub eBook.

=head1 DESCRIPTION

This module is used for converting Pod documents to ePub eBooks. The output eBook can be read on a variety of hardware and software eBook readers.

Pod is Perl's I<Plain Old Documentation> format, see L<http://perldoc.perl.org/perlpod.html>. EPub is an eBook format, see L<http://en.wikipedia.org/wiki/Epub>.

This module comes with a L<pod2epub> utility that will convert Pod to an ePub eBook.


=head1 SYNOPSIS


To create a simple filter to convert Pod to an XHTML format suitable for inclusion in an ePub eBook.

    #!/usr/bin/perl -w

    use strict;
    use App::Pod2Epub;


    my $parser = App::Pod2Epub->new();

    if (defined $ARGV[0]) {
        open IN, $ARGV[0]  or die "Couldn't open $ARGV[0]: $!\n";
    } else {
        *IN = *STDIN;
    }

    if (defined $ARGV[1]) {
        open OUT, ">$ARGV[1]" or die "Couldn't open $ARGV[1]: $!\n";
    } else {
        *OUT = *STDOUT;
    }

    $parser->output_fh(*OUT);
    $parser->parse_file(*IN);

    __END__

=head1 USING THIS MODULE

At the moment this module isn't very useful on its own. It is mainly in existence as a backend for C<pod2epub>.

It provides a framework to convert Pod documents to an XHTML format suitable for inclusion in an ePub eBook. The ePub creation is handled by L<EBook::EPUB> in C<pod2epub>. Future versions will move that functionality into this module so that it has a...

=head1 METHODS

=head2 new()

The C<new> method is used to create a new C<App::Pod2Epub> object.

=head2 Other methods

C<App::Pod2Epub> inherits all of the methods of its parent modules C<Pod::Simple> and C<Pod::Simple::XHTML>. See L<Pod::Simple> for more details if you need finer control over the output of this module.


=head1 SEE ALSO

This module also installs a L<pod2epub> command line utility. See C<pod2epub --help> for details.
