936 =head1 NAME
937
938 all2xml.pl - read various file formats and dump XML for SWISH-E
939
940 =head1 SYNOPSYS
941
942 $ all2xml.pl [test.conf]
943
944 =head1 DESCRIPTION
945
946 This command will read ISIS data file using OpenIsis perl module, MARC
947 records using MARC module and optionally Micro$oft Excel files to
948 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
949 this script B<isn't general xml generator> from isis files (isis allready
950 has something like that). Output of this script is tailor-made for SWISH-E.
951
952 If no configuration file is specified, it will use default one called
953 C<all2xml.conf>.
954
955 =head1 BUGS
956
957 Documentation is really lacking. However, in true Open Source spirit, source
958 is best documentation. I even made considerable effort to comment parts
959 which are not intuitively clear, so...
