 855 =head1 NAME
 856
 857 all2xml.pl - read various file formats and dump XML for SWISH-E
 858
 859 =head1 DESCRIPTION
 860
 861 This command will read ISIS data file using OpenIsis perl module, MARC
 862 records using MARC module and optionally Micro$oft Excel files to
 863 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
 864 this script B<isn't general xml generator> from isis files (isis allready
 865 has something like that). Output of this script is tailor-made for SWISH-E.
 866
 867 =head1 BUGS
 868
 869 Documentation is really lacking. However, in true Open Source spirit, source
 870 is best documentation. I even made considerable effort to comment parts
 871 which are not intuitively clear, so...
