-=head1 NAME
-
-all2xml.pl - read various file formats and dump XML for SWISH-E
-
-=head1 DESCRIPTION
-
-This command will read ISIS data file using OpenIsis perl module, MARC
-records using MARC module and optionally Micro$oft Excel files to
-create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
-this script B<isn't general xml generator> from isis files (isis allready
-has something like that). Output of this script is tailor-made for SWISH-E.
+} # XXX if(0)
 
-=head1 BUGS
+$log->debug("lookup hash: ",Dump($webpac->{'lookup'}));
 
-Documentation is really lacking. However, in true Open Source spirit, source
-is best documentation. I even made considerable effort to comment parts
-which are not intuitively clear, so...
