919 all2xml.pl - read various file formats and dump XML for SWISH-E
920
921 =head1 DESCRIPTION
922
923 This command will read ISIS data file using OpenIsis perl module, MARC
924 records using MARC module and optionally Micro$oft Excel files to
925 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
926 this script B<isn't general xml generator> from isis files (isis allready
927 has something like that). Output of this script is tailor-made for SWISH-E.

930
931 Documentation is really lacking. However, in true Open Source spirit, source
932 is best documentation. I even made considerable effort to comment parts
933 which are not intuitively clear, so...
