679 =head1 NAME
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
