890 =head1 NAME
891
892 all2xml.pl - read various file formats and dump XML for SWISH-E
893
894 =head1 DESCRIPTION
895
896 This command will read ISIS data file using OpenIsis perl module, MARC
897 records using MARC module and optionally Micro$oft Excel files to
898 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
899 this script B<isn't general xml generator> from isis files (isis allready
900 has something like that). Output of this script is tailor-made for SWISH-E.
901
902 =head1 BUGS
903
904 Documentation is really lacking. However, in true Open Source spirit, source
905 is best documentation. I even made considerable effort to comment parts
906 which are not intuitively clear, so...
