  27 =head1 NAME
  28
  29 Koha::Template::Plugin::Koha - General Koha Template Toolkit plugin
  30
  31 =head1 SYNOPSIS
  32
  33 This plugin contains various Koha replated Template Toolkit functions
  34 to help streamline Koha and to move logic from the Perl code into the
  35 Templates when it makes sense to do so.
  36
  37 To use, first, include the line '[% USE Koha %]' at the top
  38 of the template to enable the plugin.
  39
  40 For example: [% IF Koha.Preference( 'MyPreference ) == 'SettingA' %]
  41 removes the necessity of setting a template variable in Perl code for
  42 each and every system preference, even if no evaluation of the setting
  43 is necessary.
