474 =head1 NAME
475
476 all2xml.pl - read various file formats and dump XML for SWISH-E
477
478 =head1 DESCRIPTION
479
480 This command will read ISIS data file using OpenIsis perl module, MARC
481 records using MARC module and optionally Micro$oft Excel files to
482 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
483 this script B<isn't general xml generator> from isis files (isis allready
484 has something like that). Output of this script is tailor-made for SWISH-E.
485
486 =head1 BUGS
487
488 Documentation is really lacking. However, in true Open Source spirit, source
489 is best documentation. I even made considerable effort to comment parts
490 which are not intuitively clear, so...
