 819 =head1 NAME
 820
 821 all2xml.pl - read various file formats and dump XML for SWISH-E
 822
 823 =head1 DESCRIPTION
 824
 825 This command will read ISIS data file using OpenIsis perl module, MARC
 826 records using MARC module and optionally Micro$oft Excel files to
 827 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
 828 this script B<isn't general xml generator> from isis files (isis allready
 829 has something like that). Output of this script is tailor-made for SWISH-E.
 830
 831 =head1 BUGS
 832
 833 Documentation is really lacking. However, in true Open Source spirit, source
 834 is best documentation. I even made considerable effort to comment parts
 835 which are not intuitively clear, so...
