+Customizing the Diary
+.....................
+
+ Ordinarily, the mode line of the diary buffer window indicates any
+holidays that fall on the date of the diary entries. The process of
+checking for holidays can take several seconds, so including holiday
+information delays the display of the diary buffer noticeably. If you'd
+prefer to have a faster display of the diary buffer but without the
+holiday information, set the variable `holidays-in-diary-buffer' to
+`nil'.
+
+ The variable `number-of-diary-entries' controls the number of days
+of diary entries to be displayed at one time. It affects the initial
+display when `view-diary-entries-initially' is `t', as well as the
+command `M-x diary'. For example, the default value is 1, which says
+to display only the current day's diary entries. If the value is 2,
+both the current day's and the next day's entries are displayed. The
+value can also be a vector of seven elements: for example, if the value
+is `[0 2 2 2 2 4 1]' then no diary entries appear on Sunday, the
+current date's and the next day's diary entries appear Monday through
+Thursday, Friday through Monday's entries appear on Friday, while on
+Saturday only that day's entries appear.
+
+ The variable `print-diary-entries-hook' is a normal hook run after
+preparation of a temporary buffer containing just the diary entries
+currently visible in the diary buffer. (The other, irrelevant diary
+entries are really absent from the temporary buffer; in the diary
+buffer, they are merely hidden.) The default value of this hook does
+the printing with the command `lpr-buffer'. If you want to use a
+different command to do the printing, just change the value of this
+hook. Other uses might include, for example, rearranging the lines into
+order by day and time.
+
+ You can customize the form of dates in your diary file, if neither
+the standard American nor European styles suits your needs, by setting
+the variable `diary-date-forms'. This variable is a list of patterns
+for recognizing a date. Each date pattern is a list whose elements may
+be regular expressions (*note Regexps::) or the symbols `month', `day',
+`year', `monthname', and `dayname'. All these elements serve as
+patterns that match certain kinds of text in the diary file. In order
+for the date pattern, as a whole, to match, all of its elements must
+match consecutively.
+
+ A regular expression in a date pattern matches in its usual fashion,
+using the standard syntax table altered so that `*' is a word
+constituent.
+
+ The symbols `month', `day', `year', `monthname', and `dayname' match
+the month number, day number, year number, month name, and day name of
+the date being considered. The symbols that match numbers allow
+leading zeros; those that match names allow three-letter abbreviations
+and capitalization. All the symbols can match `*'; since `*' in a
+diary entry means "any day", "any month", and so on, it should match
+regardless of the date being considered.
+
+ The default value of `diary-date-forms' in the American style is
+this:
+
+ ((month "/" day "[^/0-9]")
+ (month "/" day "/" year "[^0-9]")
+ (monthname " *" day "[^,0-9]")
+ (monthname " *" day ", *" year "[^0-9]")
+ (dayname "\\W"))
+
+Emacs matches of the diary entries with the date forms is done with the
+standard syntax table from Fundamental mode (*note Syntax Tables:
+(lispref)Syntax Tables.), but with the `*' changed so that it is a word
+constituent.
+
+ The date patterns in the list must be _mutually exclusive_ and must
+not match any portion of the diary entry itself, just the date and one
+character of whitespace. If, to be mutually exclusive, the pattern
+must match a portion of the diary entry text--beyond the whitespace
+that ends the date--then the first element of the date pattern _must_
+be `backup'. This causes the date recognizer to back up to the
+beginning of the current word of the diary entry, after finishing the
+match. Even if you use `backup', the date pattern must absolutely not
+match more than a portion of the first word of the diary entry. The
+default value of `diary-date-forms' in the European style is this list:
+
+ ((day "/" month "[^/0-9]")
+ (day "/" month "/" year "[^0-9]")
+ (backup day " *" monthname "\\W+\\<[^*0-9]")
+ (day " *" monthname " *" year "[^0-9]")
+ (dayname "\\W"))
+
+Notice the use of `backup' in the third pattern, because it needs to
+match part of a word beyond the date itself to distinguish it from the
+fourth pattern.

+
+Hebrew- and Islamic-Date Diary Entries
+......................................
+
+ Your diary file can have entries based on Hebrew or Islamic dates, as
+well as entries based on the world-standard Gregorian calendar.
+However, because recognition of such entries is time-consuming and most
+people don't use them, you must explicitly enable their use. If you
+want the diary to recognize Hebrew-date diary entries, for example, you
+must do this:
+
+ (add-hook 'nongregorian-diary-listing-hook 'list-hebrew-diary-entries)
+ (add-hook 'nongregorian-diary-marking-hook 'mark-hebrew-diary-entries)
+
+If you want Islamic-date entries, do this:
+
+ (add-hook 'nongregorian-diary-listing-hook 'list-islamic-diary-entries)
+ (add-hook 'nongregorian-diary-marking-hook 'mark-islamic-diary-entries)
+
+ Hebrew- and Islamic-date diary entries have the same formats as
+Gregorian-date diary entries, except that `H' precedes a Hebrew date
+and `I' precedes an Islamic date. Moreover, because the Hebrew and
+Islamic month names are not uniquely specified by the first three
+letters, you may not abbreviate them. For example, a diary entry for
+the Hebrew date Heshvan 25 could look like this:
+
+ HHeshvan 25 Happy Hebrew birthday!
+
+and would appear in the diary for any date that corresponds to Heshvan
+25 on the Hebrew calendar. And here is Islamic-date diary entry that
+matches Dhu al-Qada 25:
+
+ IDhu al-Qada 25 Happy Islamic birthday!
+
+and would appear in the diary for any date that corresponds to Dhu
+al-Qada 25 on the Islamic calendar.
+
+ As with Gregorian-date diary entries, Hebrew- and Islamic-date
+entries are nonmarking if they are preceded with an ampersand (`&').
+
+ Here is a table of commands used in the calendar to create diary
+entries that match the selected date and other dates that are similar
+in the Hebrew or Islamic calendar:
+
+`i h d'
+ Add a diary entry for the Hebrew date corresponding to the
+ selected date (`insert-hebrew-diary-entry').
+
+`i h m'
+ Add a diary entry for the day of the Hebrew month corresponding to
+ the selected date (`insert-monthly-hebrew-diary-entry'). This
+ diary entry matches any date that has the same Hebrew
+ day-within-month as the selected date.
+
+`i h y'
+ Add a diary entry for the day of the Hebrew year corresponding to
+ the selected date (`insert-yearly-hebrew-diary-entry'). This diary
+ entry matches any date which has the same Hebrew month and
+ day-within-month as the selected date.
+
+`i i d'
+ Add a diary entry for the Islamic date corresponding to the
+ selected date (`insert-islamic-diary-entry').
+
+`i i m'
+ Add a diary entry for the day of the Islamic month corresponding
+ to the selected date (`insert-monthly-islamic-diary-entry').
+
+`i i y'
+ Add a diary entry for the day of the Islamic year corresponding to
+ the selected date (`insert-yearly-islamic-diary-entry').
+
+ These commands work much like the corresponding commands for ordinary
+diary entries: they apply to the date that point is on in the calendar
+window, and what they do is insert just the date portion of a diary
+entry at the end of your diary file. You must then insert the rest of
+the diary entry.

-Minor Modes
-===========
-
- Minor modes are options which you can use or not. For example, Auto
-Fill mode is a minor mode in which <SPC> breaks lines between words as
-you type. All the minor modes are independent of each other and of the
-selected major mode. Most minor modes inform you in the mode line when
-they are on; for example, `Fill' in the mode line means that Auto Fill
-mode is on.
-
- Append `-mode' to the name of a minor mode to get the name of a
-command function that turns the mode on or off. Thus, the command to
-enable or disable Auto Fill mode is called `M-x auto-fill-mode'. These
-commands are usually invoked with `M-x', but you can bind keys to them
-if you wish. With no argument, the function turns the mode on if it was
-off and off if it was on. This is known as "toggling". A positive
-argument always turns the mode on, and an explicit zero argument or a
-negative argument always turns it off.
-
- Auto Fill mode allows you to enter filled text without breaking lines
-explicitly. Emacs inserts newlines as necessary to prevent lines from
-becoming too long. *Note Filling::.
-
- Overwrite mode causes ordinary printing characters to replace
-existing text instead of moving it to the right. For example, if point
-is in front of the `B' in `FOOBAR', and you type a `G' in Overwrite
-mode, it changes to `FOOGAR', instead of `FOOGBAR'.
-
- Abbrev mode allows you to define abbreviations that automatically
-expand as you type them. For example, `amd' might expand to `abbrev
-mode'. *Note Abbrevs::, for full information.

-Variables
-=========
-
- A "variable" is a Lisp symbol which has a value. Variable names can
-contain any characters, but by convention they are words separated by
-hyphens. A variable can also have a documentation string, which
-describes what kind of value it should have and how the value will be
-used.
-
- Lisp allows any variable to have any kind of value, but most
-variables that Emacs uses require a value of a certain type. Often the
-value has to be a string or a number. Sometimes we say that a certain
-feature is turned on if a variable is "non-`nil'," meaning that if the
-variable's value is `nil', the feature is off, but the feature is on
-for any other value. The conventional value to turn on the
-feature--since you have to pick one particular value when you set the
-variable--is `t'.
-
- Emacs uses many Lisp variables for internal recordkeeping, as any
-Lisp program must, but the most interesting variables for you are the
-ones that exist for the sake of customization. Emacs does not
-(usually) change the values of these variables; instead, you set the
-values, and thereby alter and control the behavior of certain Emacs
-commands. These variables are called "options". Most options are
-documented in this manual and appear in the Variable Index (*note
-Variable Index::).
-
- One example of a variable which is an option is `fill-column', which
-specifies the position of the right margin (as a number of characters
-from the left margin) to be used by the fill commands (*note Filling::).

-
-Examining and Setting Variables
--------------------------------
-
-`C-h v'
-`M-x describe-variable'
- Print the value and documentation of a variable.
-
-`M-x set-variable'
- Change the value of a variable.
-
- To examine the value of a single variable, use `C-h v'
-(`describe-variable'), which reads a variable name using the
-minibuffer, with completion. It prints both the value and the
-documentation of the variable.
-
- C-h v fill-column <RET>
-
-prints something like:
-
- fill-column's value is 75
-
- Documentation:
- *Column beyond which automatic line-wrapping should happen.
- Automatically becomes local when set in any fashion.
-
-The star at the beginning of the documentation indicates that this
-variable is an option. `C-h v' is not restricted to options; it allows
-any variable name.
-
- If you know which option you want to set, you can use `M-x
-set-variable' to set it. This prompts for the variable name in the
-minibuffer (with completion), and then prompts for a Lisp expression
-for the new value using the minibuffer a second time. For example,
-
- M-x set-variable <RET> fill-column <RET> 75 <RET>
-
-sets `fill-column' to 75, as if you had executed the Lisp expression
-`(setq fill-column 75)'.
-
- Setting variables in this way, like all means of customizing Emacs
-except where explicitly stated, affects only the current Emacs session.

-Easy Customization Interface
-----------------------------
-
- A convenient way to find the user option variables that you want to
-change, and then change them, is with `M-x customize'. This command
-creates a "customization buffer" with which you can browse through the
-Emacs user options in a logically organized structure, then edit and
-set their values. You can also use the customization buffer to save
-settings permanently. (Not all Emacs user options are included in this
-structure as of yet, but we are adding the rest.)

-* Groups: Customization Groups.
- How options are classified in a structure.
-* Changing an Option:: How to edit a value and set an option.
-* Face Customization:: How to edit the attributes of a face.

-
-Customization Groups
-....................
-
- For customization purposes, user options are organized into "groups"
-to help you find them. Groups are collected into bigger groups, all
-the way up to a master group called `Emacs'.
-
- `M-x customize' creates a customization buffer that shows the
-top-level `Emacs' group and the second-level groups immediately under
-it. It looks like this, in part:
-
- /- Emacs group: ---------------------------------------------------\
- [State]: visible group members are all at standard settings.
- Customization of the One True Editor.
- See also [Manual].
-
- [Open] Editing group
- Basic text editing facilities.
-
- [Open] External group
- Interfacing to external utilities.
-
- MORE SECOND-LEVEL GROUPS
-
- \- Emacs group end ------------------------------------------------/
-
-This says that the buffer displays the contents of the `Emacs' group.
-The other groups are listed because they are its contents. But they
-are listed differently, without indentation and dashes, because _their_
-contents are not included. Each group has a single-line documentation
-string; the `Emacs' group also has a `[State]' line.
-
- Most of the text in the customization buffer is read-only, but it
-typically includes some "editable fields" that you can edit. There are
-also "active fields"; this means a field that does something when you
-"invoke" it. To invoke an active field, either click on it with
-`Mouse-1', or move point to it and type <RET>.
-
- For example, the phrase `[Open]' that appears in a second-level
-group is an active field. Invoking the `[Open]' field for a group
-opens up a new customization buffer, which shows that group and its
-contents. This field is a kind of hypertext link to another group.
-
- The `Emacs' group does not include any user options itself, but
-other groups do. By examining various groups, you will eventually find
-the options and faces that belong to the feature you are interested in
-customizing. Then you can use the customization buffer to set them.
-
- You can view the structure of customization groups on a larger scale
-with `M-x customize-browse'. This command creates a special kind of
-customization buffer which shows only the names of the groups (and
-options and faces), and their structure.
-
- In this buffer, you can show the contents of a group by invoking
-`[+]'. When the group contents are visible, this button changes to
-`[-]'; invoking that hides the group contents.
-
- Each group, option or face name in this buffer has an active field
-which says `[Group]', `[Option]' or `[Face]'. Invoking that active
-field creates an ordinary customization buffer showing just that group
-and its contents, just that option, or just that face. This is the way
-to set values in it.
