480 =head1 NAME
481
482 all2xml.pl - read various file formats and dump XML for SWISH-E
483
484 =head1 DESCRIPTION
485
486 This command will read ISIS data file using OpenIsis perl module, MARC
487 records using MARC module and optionally Micro$oft Excel files to
488 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
489 this script B<isn't general xml generator> from isis files (isis allready
490 has something like that). Output of this script is tailor-made for SWISH-E.
491
492 =head1 BUGS
493
494 Documentation is really lacking. However, in true Open Source spirit, source
495 is best documentation. I even made considerable effort to comment parts
496 which are not intuitively clear, so...
