 888 =head1 NAME
 889
 890 all2xml.pl - read various file formats and dump XML for SWISH-E
 891
 892 =head1 DESCRIPTION
 893
 894 This command will read ISIS data file using OpenIsis perl module, MARC
 895 records using MARC module and optionally Micro$oft Excel files to
 896 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
 897 this script B<isn't general xml generator> from isis files (isis allready
 898 has something like that). Output of this script is tailor-made for SWISH-E.
 899
 900 =head1 BUGS
 901
 902 Documentation is really lacking. However, in true Open Source spirit, source
 903 is best documentation. I even made considerable effort to comment parts
 904 which are not intuitively clear, so...
