=head1 NAME

tei2korapxml - Conversion of TEI P5 based formats to KorAP-XML

=head1 SYNOPSIS

  cat corpus.i5.xml | tei2korapxml > corpus.korapxml.zip

=head1 DESCRIPTION

C<tei2korapxml> is a script to convert TEI P5 and
L<I5|https://www1.ids-mannheim.de/kl/projekte/korpora/textmodell.html>
based documents to the
L<KorAP-XML format|https://github.com/KorAP/KorAP-XML-Krill#about-korap-xml>.
If no specific input is defined, data is
read from C<STDIN>. If no specific output is defined, data is written
to C<STDOUT>.

This program is usually called from inside another script.

=head1 FORMATS

=head2 Input restrictions

=over 2

=item

utf8 encoded

=item

TEI P5 formatted input with certain restrictions:

=over 4

=item

B<mandatory>: text-header with integrated textsigle, text-body

=item

B<optional>: corp-header with integrated corpsigle,
doc-header with integrated docsigle

=back

=item

All tokens inside the primary text may not be
newline seperated, because newlines are removed
(see L<KorAP::XML::TEI::Data>) and a conversion of newlines
into blanks between 2 tokens could lead to additional blanks,
where there should be none (e.g.: punctuation characters like C<,> or
C<.> should not be seperated from their predecessor token).
(see also code section C<~ whitespace handling ~>).

=back

=head2 Notes on the output

=over 2

=item

zip file output (default on C<stdout>) with utf8 encoded entries
(which together form the KorAP-XML format)

=back

=head1 INSTALLATION

C<tei2korapxml> requires L<libxml2-dev> bindings to build. When
these bindings are available, the preferred way to install the script is
to use L<cpanm|App::cpanminus>.

  $ cpanm https://github.com/KorAP/KorAP-XML-TEI.git

In case everything went well, the C<tei2korapxml> tool will
be available on your command line immediately.

Minimum requirement for L<KorAP::XML::TEI> is Perl 5.16.

=head1 OPTIONS

=over 2

=item B<--root|-r>

The root directory for output. Defaults to C<.>.

=item B<--help|-h>

Print help information.

=item B<--version|-v>

Print version information.

=item B<--tokenizer-call|-tc>

Call an external tokenizer process, that will tokenize
a single line from STDIN and outputs one token per line.

=item B<--tokenizer-korap|-tk>

Use the standard KorAP/DeReKo tokenizer.

=item B<--use-intern-tokenization|-ti>

Tokenize the data using two embedded tokenizers,
that will take an I<Aggressive> and a I<conservative>
approach.

=item B<--log|-l>
