28 =head1 NAME
29
30 run.pl - start WebPAC indexing
31
32 B<this command will probably go away. Don't get used to it!>
33
34 Options:
35
36 =over 4
37
38 =item --offset 42
39
40 start loading (all) databases at offset 42
41
42 =item --limit 100
43
44 limit loading to 100 records
45
46 =item --clean
47
48 remove database and Hyper Estraier index before indexing
49
50 =item --only=database_name/input_filter
51
52 reindex just single database (legacy name is --one)
53
54 C</input_filter> is optional part which can be C<name>
55 or C<type> from input
56
57 =item --config conf/config.yml
58
59 path to YAML configuration file
60
61 =item --stats
62
63 disable indexing, modify_* in configuration and dump statistics about field
64 and subfield usage for each input
65
66 =item --validate path/to/validation_file
67
68 turn on extra validation of imput records, see L<WebPAC::Validation>
69
70 =item --marc-normalize conf/normalize/mapping.pl
71
72 This option specifies normalisation file for MARC creation
73
74 =item --marc-output out/marc/test.marc
75
76 Optional path to output file
77
78 =item --marc-lint
79
80 By default turned on if C<--marc-normalize> is used. You can disable lint
81 messages with C<--no-marc-lint>.
82
83 =item --marc-dump
84
85 Force dump or input and marc record for debugging.
86
87 =item --parallel 4
88
89 Run databases in parallel (aproximatly same as number of processors in
90 machine if you want to use full load)
91
92 =item --only-links
93
94 Create just links
95
96 =item --merge
97
98 Create merged index of databases which have links
99
100 =back
101
102 =cut
