507 =head1 NAME
508
509 all2xml.pl - read various file formats and dump XML for SWISH-E
510
511 =head1 DESCRIPTION
512
513 This command will read ISIS data file using OpenIsis perl module, MARC
514 records using MARC module and optionally Micro$oft Excel files to
515 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
516 this script B<isn't general xml generator> from isis files (isis allready
517 has something like that). Output of this script is tailor-made for SWISH-E.
518
519 =head1 BUGS
520
521 Documentation is really lacking. However, in true Open Source spirit, source
522 is best documentation. I even made considerable effort to comment parts
523 which are not intuitively clear, so...
