1050
1051 This command will read ISIS data file using Biblio::Isis perl module, MARC
1052 records using MARC::File module and optionally Micro$oft Excel files to
1053 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
1054 this script B<isn't general xml generator> from isis files (isis allready
1055 has something like that). Output of this script is tailor-made for SWISH-E.
1056
1057 If no configuration file is specified, it will use default one called
1058 C<all2xml.conf>.
