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

947 which are not intuitively clear, so...
