427 =head1 NAME
428
429 isis2xml.pl - read isis file and dump XML
430
431 =head1 DESCRIPTION
432
433 This command will read ISIS data file using OpenIsis perl module and
434 create XML file for usage with I<SWISH-E>
435 indexer. Dispite it's name, this script B<isn't general xml generator>
436 from isis files (isis allready has something like that). Output of this
437 script is tailor-made for SWISH-E.
