29 =head1 NAME
30
31 run.pl - start WebPAC indexing
32
33 B<this command will probably go away. Don't get used to it!>
34
35 =head1 OPTIONS
36
37 =over 4
38
39 =item --offset 42
40
41 start loading (all) databases at offset 42
42
43 =item --limit 100
44
45 limit loading to 100 records
46
47 =item --clean
48
49 remove database and Hyper Estraier index before indexing
50
51 =item --only=database_name/input_filter
52
53 reindex just single database (legacy name is --one)
54
55 C</input_filter> is optional part which can be C<name>
56 or C<type> from input
57
58 =item --config conf/config.yml
59
60 path to YAML configuration file
61
62 =item --stats
63
64 disable indexing, modify_* in configuration and dump statistics about field
65 and subfield usage for each input
66
67 =item --validate path/to/validation_file
68
69 turn on extra validation of imput records, see L<WebPAC::Validation>
70
71 =item --marc-generate
72
73 Generate MARC file. This will automatically be on if file contains C<marc*> directives.
74 You can use this option as C<--no-marc-generate> to disable MARC generation.
75
76 =item --marc-lint
77
78 By default turned on if normalisation file has C<marc*> directives. You can disable lint
79 messages with C<--no-marc-lint>.
80
81 =item --marc-dump
82
83 Force dump or input and marc record for debugging.
84
85 =item --parallel 4
86
87 Run databases in parallel (aproximatly same as number of processors in
88 machine if you want to use full load)
89
90 =item --only-links
91
92 Create just links
93
94 =item --merge
95
96 Create merged index of databases which have links
97
98 =back
99
100 =cut
