796 =head1 NAME
797
798 all2xml.pl - read various file formats and dump XML for SWISH-E
799
800 =head1 DESCRIPTION
801
802 This command will read ISIS data file using OpenIsis perl module, MARC
803 records using MARC module and optionally Micro$oft Excel files to
804 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
805 this script B<isn't general xml generator> from isis files (isis allready
806 has something like that). Output of this script is tailor-made for SWISH-E.
807
808 =head1 BUGS
809
810 Documentation is really lacking. However, in true Open Source spirit, source
811 is best documentation. I even made considerable effort to comment parts
812 which are not intuitively clear, so...
