888 =head1 NAME
889
890 all2xml.pl - read various file formats and dump XML for SWISH-E
891
892 =head1 DESCRIPTION
893
894 This command will read ISIS data file using OpenIsis perl module, MARC
895 records using MARC module and optionally Micro$oft Excel files to
896 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
897 this script B<isn't general xml generator> from isis files (isis allready
898 has something like that). Output of this script is tailor-made for SWISH-E.
899
900 =head1 BUGS
901
902 Documentation is really lacking. However, in true Open Source spirit, source
903 is best documentation. I even made considerable effort to comment parts
904 which are not intuitively clear, so...
