=head1 NAME |
| 1020 |
|
| 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 |

=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... |
