  54 =head1 NAME
  55
  56 Koha::SVC
  57
  58 =head1 DESCRIPTION
  59
  60 Call Koha's C</svc/> API to fetch/update records
  61
  62 This script can be used from other scripts as C<Koha::SVC> module or run
  63 directly using syntax:
  64
  65   koha-svc.pl http://koha-dev:8080/cgi-bin/koha/svc svc-user svc-password $biblionumber [bib-42.xml]
  66
  67 If called without last argument (MARCXML filename) it will fetch C<$biblionumber> from Koha and create
  68 C<bib-$biblionumber.xml> file from it. When called with xml filename, it will update record in Koha.
  69
  70 This script is intentionally separate from Koha itself and dependencies which Koha has under
  71 assumption that you might want to run it on another machine (or create custom script which mungles
  72 Koha's records from other machine without bringing all Koha dependencies with it).
  73
  74 =head1 USAGE
  75
  76 This same script can be used as module (as it defines T<Koha::SVC> package) using
  77
  78   require "koha-svc.pl"
  79
  80 at beginning of script. Rest of API is described below. Example of its usage is at beginning of this script.

  87     password => 'svc-password',
  88     debug    => 0,
  89   );
  90
  91 URL must point to Koha's B<intranet> address and port.
  92
  93 Specified user must have C<editcatalogue> permission.
