282     =head1 NAME
283    
284     isis2xml.pl - read isis file and dump XML
285    
286     =head1 DESCRIPTION
287    
288     This command will read ISIS data file using OpenIsis perl module and
289     create XML file for usage with I<SWISH-E>
290     indexer. Dispite it's name, this script B<isn't general xml generator>
291     from isis files (isis allready has something like that). Output of this
292     script is tailor-made for SWISH-E.
