867 =head1 NAME
868
869 all2xml.pl - read various file formats and dump XML for SWISH-E
870
871 =head1 DESCRIPTION
872
873 This command will read ISIS data file using OpenIsis perl module, MARC
874 records using MARC module and optionally Micro$oft Excel files to
875 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
876 this script B<isn't general xml generator> from isis files (isis allready
877 has something like that). Output of this script is tailor-made for SWISH-E.
878
879 =head1 BUGS
880
881 Documentation is really lacking. However, in true Open Source spirit, source
882 is best documentation. I even made considerable effort to comment parts
883 which are not intuitively clear, so...
