25 =head1 NAME
26
27 run.pl - start WebPAC indexing
28
29 B<this command will probably go away. Don't get used to it!>
30
31 Options:
32
33 =over 4
34
35 =item --offset 42
36
37 start loading (all) databases at offset 42
38
39 =item --limit 100
40
41 limit loading to 100 records
42
43 =item --clean
44
45 remove database and Hyper Estraier index before indexing
46
47 =item --only=database_name/input_filter
48
49 reindex just single database (legacy name is --one)
50
51 C</input_filter> is optional part which can be C<name>
52 or C<type> from input
53
54 =item --config conf/config.yml
55
56 path to YAML configuration file
57
58 =item --stats
59
60 disable indexing and dump statistics about field and subfield
61 usage for each input
62
63 =item --validate path/to/validation_file
64
65 turn on extra validation of imput records, see L<WebPAC::Validation>
66
67 =item --marc-normalize conf/normalize/mapping.pl
68
69 This option specifies normalisation file for MARC creation
70
71 =item --marc-output out/marc/test.marc
72
73 Optional path to output file
74
75 =item --marc-lint
76
77 By default turned on if C<--marc-normalize> is used. You can disable lint
78 messages with C<--no-marc-lint>.
79
80 =item --marc-dump
81
82 Force dump or input and marc record for debugging.
