930 =head1 NAME
931
932 all2xml.pl - read various file formats and dump XML for SWISH-E
933
934 =head1 SYNOPSYS
935
936 $ all2xml.pl [test.conf]
937
938 =head1 DESCRIPTION
939
940 This command will read ISIS data file using OpenIsis perl module, MARC
941 records using MARC module and optionally Micro$oft Excel files to
942 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
943 this script B<isn't general xml generator> from isis files (isis allready
944 has something like that). Output of this script is tailor-made for SWISH-E.
945
946 If no configuration file is specified, it will use default one called
947 C<all2xml.conf>.
948
949 =head1 BUGS
950
951 Documentation is really lacking. However, in true Open Source spirit, source
952 is best documentation. I even made considerable effort to comment parts
953 which are not intuitively clear, so...
