867     =head1 NAME
868    
869 dpavlin 81 all2xml.pl - read various file formats and dump XML for SWISH-E
870 dpavlin 3
871     =head1 DESCRIPTION
872    
873 dpavlin 81 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.

879 dpavlin 81 =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...
