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