 593 =head1 NAME
 594
 595 all2xml.pl - read various file formats and dump XML for SWISH-E
 596
 597 =head1 DESCRIPTION
 598
 599 This command will read ISIS data file using OpenIsis perl module, MARC
 600 records using MARC module and optionally Micro$oft Excel files to
 601 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
 602 this script B<isn't general xml generator> from isis files (isis allready
 603 has something like that). Output of this script is tailor-made for SWISH-E.
 604
 605 =head1 BUGS
 606
 607 Documentation is really lacking. However, in true Open Source spirit, source
 608 is best documentation. I even made considerable effort to comment parts
 609 which are not intuitively clear, so...
