939    
940 dpavlin 81 all2xml.pl - read various file formats and dump XML for SWISH-E
941 dpavlin 3
942 dpavlin 298 =head1 SYNOPSYS
943    
944     $ all2xml.pl [test.conf]
945    
946 dpavlin 3 =head1 DESCRIPTION
947    
948 dpavlin 81 This command will read ISIS data file using OpenIsis perl module, MARC
949     records using MARC module and optionally Micro$oft Excel files to
950     create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
951     this script B<isn't general xml generator> from isis files (isis allready
952     has something like that). Output of this script is tailor-made for SWISH-E.
953 dpavlin 3
954 dpavlin 298 If no configuration file is specified, it will use default one called
955     C<all2xml.conf>.
956    
957 dpavlin 81 =head1 BUGS
958    
959     Documentation is really lacking. However, in true Open Source spirit, source
960     is best documentation. I even made considerable effort to comment parts
961     which are not intuitively clear, so...
