542 =head1 NAME
543
544 all2xml.pl - read various file formats and dump XML for SWISH-E
545
546 =head1 DESCRIPTION
547
548 This command will read ISIS data file using OpenIsis perl module, MARC
549 records using MARC module and optionally Micro$oft Excel files to
550 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
551 this script B<isn't general xml generator> from isis files (isis allready
552 has something like that). Output of this script is tailor-made for SWISH-E.
553
554 =head1 BUGS
555
556 Documentation is really lacking. However, in true Open Source spirit, source
557 is best documentation. I even made considerable effort to comment parts
558 which are not intuitively clear, so...
