928 dpavlin 81 all2xml.pl - read various file formats and dump XML for SWISH-E

934 dpavlin 3 =head1 DESCRIPTION
935    
936 dpavlin 81 This command will read ISIS data file using OpenIsis perl module, MARC
937     records using MARC module and optionally Micro$oft Excel files to
938     create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
939     this script B<isn't general xml generator> from isis files (isis allready
940     has something like that). Output of this script is tailor-made for SWISH-E.
941 dpavlin 3
942 dpavlin 303 If no configuration file is specified, it will use default one called
943     C<all2xml.conf>.

945 dpavlin 81 =head1 BUGS
946    
947     Documentation is really lacking. However, in true Open Source spirit, source
948     is best documentation. I even made considerable effort to comment parts
949     which are not intuitively clear, so...
