290 =head1 NAME
291
292 isis2xml.pl - read isis file and dump XML
293
294 =head1 DESCRIPTION
295
296 This command will read ISIS data file using OpenIsis perl module and
297 create XML file for usage with I<SWISH-E>
298 indexer. Dispite it's name, this script B<isn't general xml generator>
299 from isis files (isis allready has something like that). Output of this
300 script is tailor-made for SWISH-E.
