=head1 NAME

pod2github - Convert POD text to Github flavored markdown

=head1 VERSION

version 1.000


    # parse STDIN, print to STDOUT
    $ pod2github < POD_File > Markdown_File

    # parse file, print to STDOUT
    $ pod2github input.pod

    # parse file, print to file
    $ pod2github input.pod output.mkdn

    # parse STDIN, print to file
    $ pod2github - output.mkdn


This program uses L<Pod::Markdown::Github> to convert POD into Github Markdown sources.

UTF-8 is the default output encoding
if no encoding options are specified (see L</OPTIONS>).

It accepts two optional arguments:

=over 4

=item *

input pod file (defaults to C<STDIN>)

=item *

output markdown file (defaults to C<STDOUT>)


=head1 OPTIONS


=item --html-encode-chars

A list of characters to encode as HTML entities.
Pass a regexp character class, or C<1> to mean control chars, high-bit chars, and C<< <&>"' >>.

See L<Pod::Markdown/html_encode_chars> for more information.

=item --match-encoding (-m)

Use the same C<< =encoding >> as the input pod for the output file.

=item --output-encoding (-e)

Specify the encoding for the output file.

=item --utf8 (-u)

Alias for C<< -e UTF-8 >>.


=head1 SEE ALSO

This program is pretty much a straight copy of pod2markdown, which is in turn 
strongly based on C<pod2mdwn> from L<Module::Build::IkiWiki>.
