-  Here are the commands to select dates based on the Mayan calendar:
-
-@table @kbd
-@item g m l
-Move to a date specified by the long count calendar
-(@code{calendar-mayan-goto-long-count-date}).
-@item g m n t
-Move to the next occurrence of a place in the
-tzolkin calendar (@code{calendar-mayan-next-tzolkin-date}).
-@item g m p t
-Move to the previous occurrence of a place in the
-tzolkin calendar (@code{calendar-mayan-previous-tzolkin-date}).
-@item g m n h
-Move to the next occurrence of a place in the
-haab calendar (@code{calendar-mayan-next-haab-date}).
-@item g m p h
-Move to the previous occurrence of a place in the
-haab calendar (@code{calendar-mayan-previous-haab-date}).
-@item g m n c
-Move to the next occurrence of a place in the

-@cindex Mayan long count
-  To understand these commands, you need to understand the Mayan calendars.
-The @dfn{long count} is a counting of days with these units:
-
-@display
-1 kin = 1 day@ @ @ 1 uinal = 20 kin@ @ @ 1 tun = 18 uinal
-1 katun = 20 tun@ @ @ 1 baktun = 20 katun
-@end display
-
-@kindex g m @r{(Calendar mode)}
-@findex calendar-mayan-goto-long-count-date
-@noindent
-Thus, the long count date 12.16.11.16.6 means 12 baktun, 16 katun, 11
-tun, 16 uinal, and 6 kin.  The Emacs calendar can handle Mayan long
-count dates as early as 7.17.18.13.3, but no earlier.  When you use the
-@kbd{g m l} command, type the Mayan long count date with the baktun,
-katun, tun, uinal, and kin separated by periods.

-@findex calendar-mayan-next-tzolkin-date
-@cindex Mayan tzolkin calendar
-  The Mayan tzolkin calendar is a cycle of 260 days formed by a pair of
-independent cycles of 13 and 20 days.  Since this cycle repeats
-endlessly, Emacs provides commands to move backward and forward to the
-previous or next point in the cycle.  Type @kbd{g m p t} to go to the
-previous tzolkin date; Emacs asks you for a tzolkin date and moves point
-to the previous occurrence of that date.  Similarly, type @kbd{g m n t}
-to go to the next occurrence of a tzolkin date.

-@findex calendar-mayan-previous-haab-date
-@findex calendar-mayan-next-haab-date
-@cindex Mayan haab calendar
-  The Mayan haab calendar is a cycle of 365 days arranged as 18 months
-of 20 days each, followed by a 5-day monthless period.  Like the tzolkin
-cycle, this cycle repeats endlessly, and there are commands to move
-backward and forward to the previous or next point in the cycle.  Type
-@kbd{g m p h} to go to the previous haab date; Emacs asks you for a haab
-date and moves point to the previous occurrence of that date.
-Similarly, type @kbd{g m n h} to go to the next occurrence of a haab
-date.
-
-@c This is omitted because it is too long for smallbook format.
-@c @findex calendar-mayan-previous-calendar-round-date
-@findex calendar-mayan-next-calendar-round-date
-@cindex Mayan calendar round
-  The Maya also used the combination of the tzolkin date and the haab
-date.  This combination is a cycle of about 52 years called a
-@emph{calendar round}.  If you type @kbd{g m p c}, Emacs asks you for
-both a haab and a tzolkin date and then moves point to the previous
-occurrence of that combination.  Use @kbd{g m n c} to move point to the
-next occurrence of a combination.  These commands signal an error if the
-haab/tzolkin date combination you have typed is impossible.
-
-  Emacs uses strict completion (@pxref{Completion Exit}) whenever it
-asks you to type a Mayan name, so you don't have to worry about
-spelling.
