// Distributed under the same terms as the calendar itself.

// Please note that the following array of short day names (and the same goes
// for short month names, _SMN) isn't absolutely necessary.    We give it here
// for exemplification on how one can customize the short day names, but if
// they are simply the first N letters of the full name you can simply say:
//
//     Calendar._SDN_len = N; // short day name length
//     Calendar._SMN_len = N; // short month name length
//
// If N = 3 then this is not needed either since we assume a value of 3 if not
// present, to be compatible with translation files that were written before
// this feature.
