385 isis2xml.pl - read isis file and dump XML
386
387 =head1 DESCRIPTION
388
389 This command will read ISIS data file using OpenIsis perl module and
390 create XML file for usage with I<SWISH-E>
391 indexer. Dispite it's name, this script B<isn't general xml generator>
392 from isis files (isis allready has something like that). Output of this
393 script is tailor-made for SWISH-E.
