217 =head1 NAME
218
219 isis2xml.pl - read isis file and dump XML
220
221 =head1 DESCRIPTION
222
223 This command will read ISIS data file using OpenIsis perl module and
224 create XML file for usage with I<SWISH-E>
225 indexer. Dispite it's name, this script B<isn't general xml generator>
226 from isis files (isis allready has something like that). Output of this
227 script is tailor-made for SWISH-E.
