580 =head1 DESCRIPTION
581
582 This command will read ISIS data file using OpenIsis perl module, MARC
583 records using MARC module and optionally Micro$oft Excel files to
584 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
585 this script B<isn't general xml generator> from isis files (isis allready
586 has something like that). Output of this script is tailor-made for SWISH-E.

591 is best documentation. I even made considerable effort to comment parts
592 which are not intuitively clear, so...
