+
+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 I5 based documents
+to the KorAP-XML format. 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 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.
+
