 874 =head1 NAME
 875
 876 all2xml.pl - read various file formats and dump XML for SWISH-E
 877
 878 =head1 DESCRIPTION
 879
 880 This command will read ISIS data file using OpenIsis perl module, MARC
 881 records using MARC module and optionally Micro$oft Excel files to
 882 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
 883 this script B<isn't general xml generator> from isis files (isis allready
 884 has something like that). Output of this script is tailor-made for SWISH-E.
 885
 886 =head1 BUGS
 887
 888 Documentation is really lacking. However, in true Open Source spirit, source
 889 is best documentation. I even made considerable effort to comment parts
 890 which are not intuitively clear, so...
