 =head1 NAME
 
-isis2xml.pl - read isis file and dump XML
+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 and
-create 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.
+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.
+
+=head1 BUGS
+
+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...
