1061
1062 This command will read ISIS data file using Biblio::Isis perl module, MARC
1063 records using MARC::File module and optionally Micro$oft Excel files to
1064 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
1065 this script B<isn't general xml generator> from isis files (isis allready
1066 has something like that). Output of this script is tailor-made for SWISH-E.
1067
1068 If no configuration file is specified, it will use default one called
1069 C<all2xml.conf>.

1074 is best documentation. I even made considerable effort to comment parts
