282 =head1 NAME
283
284 isis2xml.pl - read isis file and dump XML
285
286 =head1 DESCRIPTION
287
288 This command will read ISIS data file using OpenIsis perl module and
289 create XML file for usage with I<SWISH-E>
290 indexer. Dispite it's name, this script B<isn't general xml generator>
291 from isis files (isis allready has something like that). Output of this
292 script is tailor-made for SWISH-E.
