=head1 OPTIONS

=over 2

=item B<--input|-i> <directory|file>

Directory or archive file of documents to index.

=item B<--output|-o> <directory|file>

=item B<--overwrite|-w>

Overwrite files that already exist.

=item B<--token|-t> <foundry>[#<file>]

Define the default tokenization by specifying
the name of the foundry and optionally the name
of the layer-file. Defaults to C<OpenNLP#tokens>.

=item B<--skip|-s> <foundry>[#<layer>]

Skip specific foundries by specifying the name
or specific layers by defining the name
with a # in front of the foundry,
e.g. Mate#Morpho. Alternatively you can skip C<#ALL>.
Can be set multiple times.

=item B<--anno|-a> <foundry>#<layer>

Allow specific annotion foundries and layers by defining them
combining the foundry name with a C<#> and the layer name.

=item B<--primary|-p>

Output primary data or not. Defaults to C<true>.
Can be flagged using --no-primary as well.
This is deprecated.

=item B<--jobs|-j>

Define the number of concurrent jobs in seperated forks

This is deprecated.

=item B<--pretty|-y>

Pretty print JSON output. Defaults to C<false>.

=item B<--gzip|-z>

Print this document.

=item B<--version|-v>

=head1 ANNOTATION SUPPORT

L<KorAP::XML::Krill> has built-in importer for some annotation foundries and layers
developed in the KorAP project that are part of the KorAP preprocessing pipeline.
The base foundry with paragraphs, sentences, and the text element are mandatory for
L<Krill|https://github.com/KorAP/Krill>.
