+=head1 NAME
+
+isis2xml.pl - read isis file and dump XML
+
+=head1 DESCRIPTION
+
+This command will read ISIS data file using OpenIsis perl module and
+create XML file for usage with I<SWISH-E>
+indexer. Dispite it's name, this script B<isn't general xml generator>
+from isis files (isis allready has something like that). Output of this
+script is tailor-made for SWISH-E.
