Experimental support for dBase .dbf files. Usege like this in all2xml.conf:

[hda]
       dbf_file=/data/drustvene/hda/ISO.DBF
       type=dbf

1019     =head1 NAME
1020    
1021 dpavlin 81 all2xml.pl - read various file formats and dump XML for SWISH-E
1022 dpavlin 3
1023 dpavlin 298 =head1 SYNOPSYS
1024    
1025     $ all2xml.pl [test.conf]
1026    
1027 dpavlin 3 =head1 DESCRIPTION
1028    
1029 dpavlin 650 This command will read ISIS data file using Biblio::Isis perl module, MARC
1030     records using MARC::File module and optionally Micro$oft Excel files to
1031 dpavlin 81 create one XML file for usage with I<SWISH-E> indexer. Dispite it's name,
1032     this script B<isn't general xml generator> from isis files (isis allready
1033     has something like that). Output of this script is tailor-made for SWISH-E.
1034 dpavlin 3
1035 dpavlin 298 If no configuration file is specified, it will use default one called
1036     C<all2xml.conf>.

1038 dpavlin 81 =head1 BUGS
1039    
1040     Documentation is really lacking. However, in true Open Source spirit, source
1041     is best documentation. I even made considerable effort to comment parts
1042     which are not intuitively clear, so...
