910 =head1 NAME
911
912 all2xml.pl - read various file formats and dump XML for SWISH-E
913
914 =head1 SYNOPSYS
915
916 $ all2xml.pl [test.conf]
917
918 =head1 DESCRIPTION
919
920 This command will read ISIS data file using IsisDB perl module, MARC
921 records using MARC module and optionally Micro$oft Excel files to
922 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
923 this script B<isn't general xml generator> from isis files (isis allready
924 has something like that). Output of this script is tailor-made for SWISH-E.
925
926 If no configuration file is specified, it will use default one called
927 C<all2xml.conf>.
928
929 =head1 BUGS
930
931 Documentation is really lacking. However, in true Open Source spirit, source
932 is best documentation. I even made considerable effort to comment parts
933 which are not intuitively clear, so...
