 ;;; Commentary:
 
-;; This collection of functions implements the features of calendar.el,
-;; diary.el, and holidays.el that deal with the Chinese calendar.  The rules
-;; used for the Chinese calendar are those of Baolin Liu (see L. E. Doggett's
-;; article "Calendars" in the Explanatory Supplement to the Astronomical
-;; Almanac, second edition, 1992) for the calendar as revised at the beginning
-;; of the Qing dynasty in 1644.  The nature of the astronomical calculations
-;; is such that precise calculations cannot be made without great expense in
-;; time, so that the calendars produced may not agree perfectly with published
-;; tables--but no two pairs of published tables agree perfectly either!  Liu's
-;; rules produce a calendar for 2033 which is not accepted by all authorities.
-;; The date of Chinese New Year is correct from 1644-2051.
-
-;; Technical details of all the calendrical calculations can be found in
-;; ``Calendrical Calculations: The Millennium Edition'' by Edward M. Reingold
-;; and Nachum Dershowitz, Cambridge University Press (2001).
