 916 =head1 DESCRIPTION
 917
 918 This command will read ISIS data file using OpenIsis perl module, MARC
 919 records using MARC module and optionally Micro$oft Excel files to
 920 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
 921 this script B<isn't general xml generator> from isis files (isis allready
 922 has something like that). Output of this script is tailor-made for SWISH-E.
 923
 924 If no configuration file is specified, it will use default one called
 925 C<all2xml.conf>.
