 926 =head1 DESCRIPTION
 927
 928 This command will read ISIS data file using OpenIsis perl module, MARC
 929 records using MARC module and optionally Micro$oft Excel files to
 930 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
 931 this script B<isn't general xml generator> from isis files (isis allready
 932 has something like that). Output of this script is tailor-made for SWISH-E.
 933
 934 If no configuration file is specified, it will use default one called
 935 C<all2xml.conf>.
