 680
 681 all2xml.pl - read various file formats and dump XML for SWISH-E
 682
 683 =head1 DESCRIPTION
 684
 685 This command will read ISIS data file using OpenIsis perl module, MARC
 686 records using MARC module and optionally Micro$oft Excel files to
 687 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
 688 this script B<isn't general xml generator> from isis files (isis allready
 689 has something like that). Output of this script is tailor-made for SWISH-E.
 690
 691 =head1 BUGS
 692
 693 Documentation is really lacking. However, in true Open Source spirit, source
 694 is best documentation. I even made considerable effort to comment parts
 695 which are not intuitively clear, so...
