 832 =head1 NAME
 833
 834 all2xml.pl - read various file formats and dump XML for SWISH-E
 835
 836 =head1 DESCRIPTION
 837
 838 This command will read ISIS data file using OpenIsis perl module, MARC
 839 records using MARC module and optionally Micro$oft Excel files to
 840 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
 841 this script B<isn't general xml generator> from isis files (isis allready
 842 has something like that). Output of this script is tailor-made for SWISH-E.
 843
 844 =head1 BUGS
 845
 846 Documentation is really lacking. However, in true Open Source spirit, source
 847 is best documentation. I even made considerable effort to comment parts
 848 which are not intuitively clear, so...
