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

[hda]
       dbf_file=/data/drustvene/hda/ISO.DBF
       type=dbf
       dbf_codepage=cp852

dbf type will use <isis> tag in import_xml and dbf_codepage will
override codepage specified in import_xml file.

Small code refactoring.

1021 all2xml.pl - read various file formats and dump XML for SWISH-E
1022
1023 =head1 SYNOPSYS
1024
1025 $ all2xml.pl [test.conf]
1026
1027 =head1 DESCRIPTION
1028
1029 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 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
1035 If no configuration file is specified, it will use default one called
1036 C<all2xml.conf>.
1037
1038 =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...
