  79 =head1 SYNOPSIS
  80
  81 use C4::Koha;
  82
  83 =head1 DESCRIPTION
  84
  85 Koha.pm provides many functions for Koha scripts.

  92
  93   $slash_date = &slashifyDate($dash_date);
  94
  95 Takes a string of the form "DD-MM-YYYY" (or anything separated by
  96 dashes), converts it to the form "YYYY/MM/DD", and returns the result.

 112     # We could match on 'lib' and 'tab' (and 'mandatory', & more to come!)
 113     # But real MARC subfields are always single-character
 114     # so it really is safer just to check the length
