 882 =head1 NAME
 883
 884 all2xml.pl - read various file formats and dump XML for SWISH-E
 885
 886 =head1 DESCRIPTION
 887
 888 This command will read ISIS data file using OpenIsis perl module, MARC
 889 records using MARC module and optionally Micro$oft Excel files to
 890 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
 891 this script B<isn't general xml generator> from isis files (isis allready
 892 has something like that). Output of this script is tailor-made for SWISH-E.
 893
 894 =head1 BUGS
 895
 896 Documentation is really lacking. However, in true Open Source spirit, source
 897 is best documentation. I even made considerable effort to comment parts
 898 which are not intuitively clear, so...
