+Customizing Lisp Indentation
+----------------------------
+
+ The indentation pattern for a Lisp expression can depend on the
+function called by the expression. For each Lisp function, you can
+choose among several predefined patterns of indentation, or define an
+arbitrary one with a Lisp program.
+
+ The standard pattern of indentation is as follows: the second line
+of the expression is indented under the first argument, if that is on
+the same line as the beginning of the expression; otherwise, the second
+line is indented underneath the function name. Each following line is
+indented under the previous line whose nesting depth is the same.
+
+ If the variable `lisp-indent-offset' is non-`nil', it overrides the
+usual indentation pattern for the second line of an expression, so that
+such lines are always indented `lisp-indent-offset' more columns than
+the containing list.
+
+ Certain functions override the standard pattern. Functions whose
+names start with `def' always indent the second line by
+`lisp-body-indention' extra columns beyond the open-parenthesis
+starting the expression.
+
+ Individual functions can override the standard pattern in various
+ways, according to the `lisp-indent-function' property of the function
+name. (Note: `lisp-indent-function' was formerly called
+`lisp-indent-hook'). There are four possibilities for this property:
+
+`nil'
+ This is the same as no property; the standard indentation pattern
+ is used.
+
+`defun'
+ The pattern used for function names that start with `def' is used
+ for this function also.
+
+a number, NUMBER
+ The first NUMBER arguments of the function are "distinguished"
+ arguments; the rest are considered the "body" of the expression.
+ A line in the expression is indented according to whether the
+ first argument on it is distinguished or not. If the argument is
+ part of the body, the line is indented `lisp-body-indent' more
+ columns than the open-parenthesis starting the containing
+ expression. If the argument is distinguished and is either the
+ first or second argument, it is indented twice that many extra
+ columns. If the argument is distinguished and not the first or
+ second argument, the standard pattern is followed for that line.
+
+a symbol, SYMBOL
+ SYMBOL should be a function name; that function is called to
+ calculate the indentation of a line within this expression. The
+ function receives two arguments:
+ STATE
+ The value returned by `parse-partial-sexp' (a Lisp primitive
+ for indentation and nesting computation) when it parses up to
+ the beginning of this line.
+
+ POS
+ The position at which the line being indented begins.
+
+ It should return either a number, which is the number of columns of
+ indentation for that line, or a list whose first element is such a
+ number. The difference between returning a number and returning a
+ list is that a number says that all following lines at the same
+ nesting level should be indented just like this one; a list says
+ that following lines might call for different indentations. This
+ makes a difference when the indentation is computed by `C-M-q'; if
+ the value is a number, `C-M-q' need not recalculate indentation
+ for the following lines until the end of the list.

-Fortran Indentation
--------------------
-
- Special commands and features are available for indenting Fortran
-code. They make sure various syntactic entities (line numbers, comment
-line indicators, and continuation line flags) appear in the columns
-that are required for standard Fortran.

-Fortran Indentation Commands
-............................
-
-`<TAB>'
- Indent the current line (`fortran-indent-line').
-
-`M-<LFD>'
- Break the current line and set up a continuation line.
-
-`C-M-q'
- Indent all the lines of the subprogram point is in
- (`fortran-indent-subprogram').
-
- <TAB> is redefined by Fortran mode to reindent the current line for
-Fortran (`fortran-indent-line'). Line numbers and continuation markers
-are indented to their required columns, and the body of the statement
-is independently indented, based on its nesting in the program.
-
- The key `C-M-q' is redefined as `fortran-indent-subprogram', a
-command that reindents all the lines of the Fortran subprogram
-(function or subroutine) containing point.
-
- The key `M-<LFD>' is redefined as `fortran-split-line', a command to
-split a line in the appropriate fashion for Fortran. In a non-comment
-line, the second half becomes a continuation line and is indented
-accordingly. In a comment line, both halves become separate comment
-lines.

-Line Numbers and Continuation
-.............................
-
- If a number is the first non-whitespace in the line, it is assumed
-to be a line number and is moved to columns 0 through 4. (Columns are
-always counted from 0 in XEmacs.) If the text on the line starts with
-the conventional Fortran continuation marker `$', it is moved to column
-5. If the text begins with any non whitespace character in column 5,
-it is assumed to be an unconventional continuation marker and remains
-in column 5.
-
- Line numbers of four digits or less are normally indented one space.
-This amount is controlled by the variable `fortran-line-number-indent',
-which is the maximum indentation a line number can have. Line numbers
-are indented to right-justify them to end in column 4 unless that would
-require more than the maximum indentation. The default value of the
-variable is 1.
-
- Simply inserting a line number is enough to indent it according to
-these rules. As each digit is inserted, the indentation is recomputed.
-To turn off this feature, set the variable
-`fortran-electric-line-number' to `nil'. Then inserting line numbers
-is like inserting anything else.
