494    
495 dpavlin 81 all2xml.pl - read various file formats and dump XML for SWISH-E
496 dpavlin 3
497     =head1 DESCRIPTION
498    
499 dpavlin 81 This command will read ISIS data file using OpenIsis perl module, MARC
500     records using MARC module and optionally Micro$oft Excel files to
501     create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
502     this script B<isn't general xml generator> from isis files (isis allready
503     has something like that). Output of this script is tailor-made for SWISH-E.
