These hooks have the following distinct roles:
`nongregorian-diary-listing-hook' can cull dates from the diary
and each included file. Usually used for Hebrew or Islamic
diary entries in files. Applied to *each* file.
`list-diary-entries-hook' adds or manipulates diary entries from
external sources. Used, for example, to include diary entries
from other files or to sort the diary entries. Invoked *once* only,
before the display hook is run.
`diary-display-hook' does the actual display of information. If this is
nil, simple-diary-display will be used. Use add-hook to set this to
fancy-diary-display, if desired. If you want no diary display, use
add-hook to set this to ignore.
`diary-hook' is run last. This can be used for an appointment
notification function.

Sexp diary entries must be prefaced by a `sexp-diary-entry-symbol' (normally

%%(SEXP) ENTRY
Both ENTRY and DATE are globally available when the SEXP is evaluated. If the

non-nil value, ENTRY will be taken to apply to DATE; if the non-nil value is a
string, that string will be the diary entry in the fancy diary display.

if it is a weekday and the Friday before if the 21st is on a weekend:

%%(diary-date MONTH DAY YEAR &optional MARK) text
Entry applies if date is MONTH, DAY, YEAR if
`european-calendar-style' is nil, and DAY, MONTH, YEAR if
`european-calendar-style' is t. DAY, MONTH, and YEAR
can be lists of integers, the constant t, or an integer.
The constant t means all values. An optional parameter
MARK specifies a face or single-character string to use
when highlighting the day in the calendar.
%%(diary-float MONTH DAYNAME N &optional DAY MARK) text
Entry will appear on the Nth DAYNAME of MONTH.
(DAYNAME=0 means Sunday, 1 means Monday, and so on;
if N is negative it counts backward from the end of
the month. MONTH can be a list of months, a single
month, or t to specify all months. Optional DAY means
Nth DAYNAME of MONTH on or after/before DAY. DAY defaults
to 1 if N>0 and the last day of the month if N<0. An
optional parameter MARK specifies a face or single-character
string to use when highlighting the day in the calendar.
%%(diary-block M1 D1 Y1 M2 D2 Y2 &optional MARK) text
Entry will appear on dates between M1/D1/Y1 and M2/D2/Y2,
inclusive. (If `european-calendar-style' is t, the
order of the parameters should be changed to D1, M1, Y1,
D2, M2, Y2.) An optional parameter MARK specifies a face
or single-character string to use when highlighting the
day in the calendar.
%%(diary-anniversary MONTH DAY YEAR &optional MARK) text
Entry will appear on anniversary dates of MONTH DAY, YEAR.
(If `european-calendar-style' is t, the order of the
parameters should be changed to DAY, MONTH, YEAR.) Text
can contain %d or %d%s; %d will be replaced by the number
of years since the MONTH DAY, YEAR and %s will be replaced
by the ordinal ending of that number (that is, `st', `nd',
`rd' or `th', as appropriate. The anniversary of February
29 is considered to be March 1 in a non-leap year. An
optional parameter MARK specifies a face or single-character
string to use when highlighting the day in the calendar.
%%(diary-cyclic N MONTH DAY YEAR &optional MARK) text
Entry will appear every N days, starting MONTH DAY, YEAR.
(If `european-calendar-style' is t, the order of the
parameters should be changed to N, DAY, MONTH, YEAR.) Text
can contain %d or %d%s; %d will be replaced by the number
of repetitions since the MONTH DAY, YEAR and %s will
be replaced by the ordinal ending of that number (that is,
`st', `nd', `rd' or `th', as appropriate. An optional
parameter MARK specifies a face or single-character string
to use when highlighting the day in the calendar.
%%(diary-remind SEXP DAYS &optional MARKING) text
Entry is a reminder for diary sexp SEXP. DAYS is either a
single number or a list of numbers indicating the number(s)
of days before the event that the warning(s) should occur.
If the current date is (one of) DAYS before the event
indicated by EXPR, then a suitable message (as specified
by `diary-remind-message') appears. In addition to the
reminders beforehand, the diary entry also appears on
the date itself. If optional MARKING is non-nil then the
*reminders* are marked on the calendar. Marking of
reminders is independent of whether the entry *itself* is
a marking or nonmarking one.

Floating point required.
%%(diary-yahrzeit MONTH DAY YEAR) text
Text is assumed to be the name of the person; the date is
the date of death on the *civil* calendar. The diary entry
will appear on the proper Hebrew-date anniversary and on the
day before. (If `european-calendar-style' is t, the order
of the parameters should be changed to DAY, MONTH, YEAR.)

passing to `replace-match', and so will have occurrences of `\\D' to

a single `%s' which will be replaced with the text of the message's
Subject field. Any other `%' characters must be doubled, so that the
