550 =head1 NAME
551
552 all2xml.pl - read various file formats and dump XML for SWISH-E
553
554 =head1 DESCRIPTION
555
556 This command will read ISIS data file using OpenIsis perl module, MARC
557 records using MARC module and optionally Micro$oft Excel files to
558 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
559 this script B<isn't general xml generator> from isis files (isis allready
560 has something like that). Output of this script is tailor-made for SWISH-E.
561
562 =head1 BUGS
563
564 Documentation is really lacking. However, in true Open Source spirit, source
565 is best documentation. I even made considerable effort to comment parts
566 which are not intuitively clear, so...
