944 =head1 DESCRIPTION
945
946 This command will read ISIS data file using OpenIsis perl module, MARC
947 records using MARC module and optionally Micro$oft Excel files to
948 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
949 this script B<isn't general xml generator> from isis files (isis allready
950 has something like that). Output of this script is tailor-made for SWISH-E.
951
952 If no configuration file is specified, it will use default one called
953 C<all2xml.conf>.
