933 dpavlin 3 =head1 DESCRIPTION
934    
935 dpavlin 623 This command will read ISIS data file using IsisDB perl module, MARC
936 dpavlin 81 records using MARC module and optionally Micro$oft Excel files to
937     create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
938     this script B<isn't general xml generator> from isis files (isis allready
939     has something like that). Output of this script is tailor-made for SWISH-E.
940 dpavlin 3
941 dpavlin 298 If no configuration file is specified, it will use default one called
942     C<all2xml.conf>.

944 dpavlin 81 =head1 BUGS
945    
946     Documentation is really lacking. However, in true Open Source spirit, source
947     is best documentation. I even made considerable effort to comment parts
948     which are not intuitively clear, so...
