 870 =head1 NAME
 871
 872 all2xml.pl - read various file formats and dump XML for SWISH-E
 873
 874 =head1 DESCRIPTION
 875
 876 This command will read ISIS data file using OpenIsis perl module, MARC
 877 records using MARC module and optionally Micro$oft Excel files to
 878 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
 879 this script B<isn't general xml generator> from isis files (isis allready
 880 has something like that). Output of this script is tailor-made for SWISH-E.
 881
 882 =head1 BUGS
 883
 884 Documentation is really lacking. However, in true Open Source spirit, source
 885 is best documentation. I even made considerable effort to comment parts
 886 which are not intuitively clear, so...
