+@section How to Start Emacs on MS-Windows
+@cindex starting Emacs on MS-Windows
+
+  There are several ways of starting Emacs on MS-Windows:
+
+@enumerate
+@item
+@pindex runemacs.exe
+@cindex desktop shortcut, MS-Windows
+@cindex start directory, MS-Windows
+@cindex directory where Emacs starts on MS-Windows
+From the desktop shortcut icon: either double-click the left mouse
+button on the icon, or click once, then press @key{RET}.  The desktop
+shortcut should specify as its ``Target'' (in the ``Properties'' of
+the shortcut) the full absolute file name of @file{runemacs.exe},
+@emph{not} of @file{emacs.exe}.  This is because @file{runemacs.exe}
+hides the console window that would have been created if the target of
+the shortcut were @file{emacs.exe} (which is a console program, as far
+as Windows is concerned).  If you use this method, Emacs starts in the
+directory specified by the shortcut.  To control where that is,
+right-click on the shortcut, select ``Properties'', and in the
+``Shortcut'' tab modify the ``Start in'' field to your liking.
+
+@item
+From the Command Prompt window, by typing @kbd{emacs @key{RET}} at the
+prompt.  The Command Prompt window where you did that will not be
+available for invoking other commands until Emacs exits.  In this
+case, Emacs will start in the current directory of the Windows shell.

+@pindex emacsclient.exe
+@pindex emacsclientw.exe
+Via the Emacs client program, @file{emacsclient.exe} or
+@file{emacsclientw.exe}.  This allows to invoke Emacs from other
+programs, and to reuse a running Emacs process for serving editing
+jobs required by other programs.  @xref{Emacs Server}.  The difference
+between @file{emacsclient.exe} and @file{emacsclientw.exe} is that the
+former waits for Emacs to signal that the editing job is finished,
+while the latter does not wait.  Which one of them to use in each case
+depends on the expectations of the program that needs editing
+services.  If the program will use the edited files, it needs to wait
+for Emacs, so you should use @file{emacsclient.exe}.  By contrast, if
+the results of editing are not needed by the invoking program, you
+will be better off using @file{emacsclientw.exe}.  A notable situation
+where you would want @file{emacsclientw.exe} is when you right-click
+on a file in the Windows Explorer and select ``Open With'' from the
+pop-up menu.  Use the @samp{--alternate-editor=} or @samp{-a} options
+if Emacs might not be running (or not running as a server) when
+@command{emacsclient} is invoked---that will always give you an
+editor.  When invoked via @command{emacsclient}, Emacs will start in
+the current directory of the program that invoked
+@command{emacsclient}.

+@node Auto-Indentation
+@section Auto-indention of code
+
+For programming languages, an important feature of a major mode is to
+provide automatic indentation.  This is controlled in Emacs by
+@code{indent-line-function} (@pxref{Mode-Specific Indent}).
+Writing a good indentation function can be difficult and to a large
+extent it is still a black art.
+
+Many major mode authors will start by writing a simple indentation
+function that works for simple cases, for example by comparing with the
+indentation of the previous text line.  For most programming languages
+that are not really line-based, this tends to scale very poorly:
+improving such a function to let it handle more diverse situations tends
+to become more and more difficult, resulting in the end with a large,
+complex, unmaintainable indentation function which nobody dares to touch.
+
+A good indentation function will usually need to actually parse the
+text, according to the syntax of the language.  Luckily, it is not
+necessary to parse the text in as much detail as would be needed
+for a compiler, but on the other hand, the parser embedded in the
+indentation code will want to be somewhat friendly to syntactically
+incorrect code.
+
+Good maintainable indentation functions usually fall into 2 categories:
+either parsing forward from some ``safe'' starting point until the
+position of interest, or parsing backward from the position of interest.
+Neither of the two is a clearly better choice than the other: parsing
+backward is often more difficult than parsing forward because
+programming languages are designed to be parsed forward, but for the
+purpose of indentation it has the advantage of not needing to
+guess a ``safe'' starting point, and it generally enjoys the property
+that only a minimum of text will be analyzed to decide the indentation
+of a line, so indentation will tend to be unaffected by syntax errors in
+some earlier unrelated piece of code.  Parsing forward on the other hand
+is usually easier and has the advantage of making it possible to
+reindent efficiently a whole region at a time, with a single parse.
+
+Rather than write your own indentation function from scratch, it is
+often preferable to try and reuse some existing ones or to rely
+on a generic indentation engine.  There are sadly few such
+engines.  The CC-mode indentation code (used with C, C++, Java, Awk
+and a few other such modes) has been made more generic over the years,
+so if your language seems somewhat similar to one of those languages,
+you might try to use that engine.  @c FIXME: documentation?
+Another one is SMIE which takes an approach in the spirit
+of Lisp sexps and adapts it to non-Lisp languages.
+
+@menu
+* SMIE::                        A simple minded indentation engine
+@end menu
+
+@node SMIE
+@subsection Simple Minded Indentation Engine
+
+SMIE is a package that provides a generic navigation and indentation
+engine.  Based on a very simple parser using an ``operator precedence
+grammar'', it lets major modes extend the sexp-based navigation of Lisp
+to non-Lisp languages as well as provide a simple to use but reliable
+auto-indentation.
+
+Operator precedence grammar is a very primitive technology for parsing
+compared to some of the more common techniques used in compilers.
+It has the following characteristics: its parsing power is very limited,
+and it is largely unable to detect syntax errors, but it has the
+advantage of being algorithmically efficient and able to parse forward
+just as well as backward.  In practice that means that SMIE can use it
+for indentation based on backward parsing, that it can provide both
+@code{forward-sexp} and @code{backward-sexp} functionality, and that it
+will naturally work on syntactically incorrect code without any extra
+effort.  The downside is that it also means that most programming
+languages cannot be parsed correctly using SMIE, at least not without
+resorting to some special tricks (@pxref{SMIE Tricks}).

+@subsubsection SMIE Setup and Features
+
+SMIE is meant to be a one-stop shop for structural navigation and
+various other features which rely on the syntactic structure of code, in
+particular automatic indentation.  The main entry point is
+@code{smie-setup} which is a function typically called while setting
+up a major mode.
+
+@defun smie-setup grammar rules-function &rest keywords
+Setup SMIE navigation and indentation.
+@var{grammar} is a grammar table generated by @code{smie-prec2->grammar}.
+@var{rules-function} is a set of indentation rules for use on
+@code{smie-rules-function}.
+@var{keywords} are additional arguments, which can include the following
+keywords:
+@itemize
+@item
+@code{:forward-token} @var{fun}: Specify the forward lexer to use.
+@item
+@code{:backward-token} @var{fun}: Specify the backward lexer to use.
+@end itemize
+@end defun
+
+Calling this function is sufficient to make commands such as
+@code{forward-sexp}, @code{backward-sexp}, and @code{transpose-sexps} be
+able to properly handle structural elements other than just the paired
+parentheses already handled by syntax tables.  For example, if the
+provided grammar is precise enough, @code{transpose-sexps} can correctly
+transpose the two arguments of a @code{+} operator, taking into account
+the precedence rules of the language.
+
+Calling `smie-setup' is also sufficient to make TAB indentation work in
+the expected way, extends @code{blink-matching-paren} to apply to
+elements like @code{begin...end}, and provides some commands that you
+can bind in the major mode keymap.
+
+@deffn Command smie-close-block
+This command closes the most recently opened (and not yet closed) block.
+@end deffn
+
+@deffn Command smie-down-list &optional arg
+This command is like @code{down-list} but it also pays attention to
+nesting of tokens other than parentheses, such as @code{begin...end}.
+@end deffn
+
+@node Operator Precedence Grammars
+@subsubsection Operator Precedence Grammars
+
+SMIE's precedence grammars simply give to each token a pair of
+precedences: the left-precedence and the right-precedence.  We say
+@code{T1 < T2} if the right-precedence of token @code{T1} is less than
+the left-precedence of token @code{T2}.  A good way to read this
+@code{<} is as a kind of parenthesis: if we find @code{... T1 something
+T2 ...}  then that should be parsed as @code{... T1 (something T2 ...}
+rather than as @code{... T1 something) T2 ...}.  The latter
+interpretation would be the case if we had @code{T1 > T2}.  If we have
+@code{T1 = T2}, it means that token T2 follows token T1 in the same
+syntactic construction, so typically we have @code{"begin" = "end"}.
+Such pairs of precedences are sufficient to express left-associativity
+or right-associativity of infix operators, nesting of tokens like
+parentheses and many other cases.
+
+@c ¡Let's leave this undocumented to leave it more open for change!
+@c @defvar smie-grammar
+@c The value of this variable is an alist specifying the left and right
+@c precedence of each token.  It is meant to be initialized by using one of
+@c the functions below.
+@c @end defvar
+
+@defun smie-prec2->grammar table
+This function takes a @emph{prec2} grammar @var{table} and returns an
+alist suitable for use in @code{smie-setup}.  The @emph{prec2}
+@var{table} is itself meant to be built by one of the functions below.
+@end defun
+
+@defun smie-merge-prec2s &rest tables
+This function takes several @emph{prec2} @var{tables} and merges them
+into a new @emph{prec2} table.
+@end defun
+
+@defun smie-precs->prec2 precs
+This function builds a @emph{prec2} table from a table of precedences
+@var{precs}.  @var{precs} should be a list, sorted by precedence (for
+example @code{"+"} will come before @code{"*"}), of elements of the form
+@code{(@var{assoc} @var{op} ...)}, where each @var{op} is a token that
+acts as an operator; @var{assoc} is their associativity, which can be
+either @code{left}, @code{right}, @code{assoc}, or @code{nonassoc}.
+All operators in a given element share the same precedence level
+and associativity.
+@end defun
+
+@defun smie-bnf->prec2 bnf &rest resolvers
+This function lets you specify the grammar using a BNF notation.
+It accepts a @var{bnf} description of the grammar along with a set of
+conflict resolution rules @var{resolvers}, and
+returns a @emph{prec2} table.
+
+@var{bnf} is a list of nonterminal definitions of the form
+@code{(@var{nonterm} @var{rhs1} @var{rhs2} ...)} where each @var{rhs}
+is a (non-empty) list of terminals (aka tokens) or non-terminals.
+
+Not all grammars are accepted:
+@itemize
+@item
+An @var{rhs} cannot be an empty list (an empty list is never needed,
+since SMIE allows all non-terminals to match the empty string anyway).
+@item
+An @var{rhs} cannot have 2 consecutive non-terminals: each pair of
+non-terminals needs to be separated by a terminal (aka token).
+This is a fundamental limitation of operator precedence grammars.
+@end itemize
+
+Additionally, conflicts can occur:
+@itemize
+@item
+The returned @emph{prec2} table holds constraints between pairs of tokens, and
+for any given pair only one constraint can be present: T1 < T2,
+T1 = T2, or T1 > T2.
+@item
+A token can be an @code{opener} (something similar to an open-paren),
+a @code{closer} (like a close-paren), or @code{neither} of the two
+(e.g. an infix operator, or an inner token like @code{"else"}).
+@end itemize
+
+Precedence conflicts can be resolved via @var{resolvers}, which
+is a list of @emph{precs} tables (see @code{smie-precs->prec2}): for
+each precedence conflict, if those @code{precs} tables
+specify a particular constraint, then the conflict is resolved by using
+this constraint instead, else a conflict is reported and one of the
+conflicting constraints is picked arbitrarily and the others are
+simply ignored.
+@end defun
+
+@node SMIE Grammar
+@subsubsection Defining the Grammar of a Language
+
+The usual way to define the SMIE grammar of a language is by
+defining a new global variable that holds the precedence table by
+giving a set of BNF rules.
+For example, the grammar definition for a small Pascal-like language
+could look like:
+@example
+@group
+(require 'smie)
+(defvar sample-smie-grammar
+  (smie-prec2->grammar
+   (smie-bnf->prec2
+@end group
+@group
+    '((id)
+      (inst ("begin" insts "end")
+            ("if" exp "then" inst "else" inst)
+            (id ":=" exp)
+            (exp))
+      (insts (insts ";" insts) (inst))
+      (exp (exp "+" exp)
+           (exp "*" exp)
+           ("(" exps ")"))
+      (exps (exps "," exps) (exp)))
+@end group
+@group
+    '((assoc ";"))
+    '((assoc ","))
+    '((assoc "+") (assoc "*")))))
+@end group
+@end example
+
+@noindent
+A few things to note:
+
+@itemize
+@item
+The above grammar does not explicitly mention the syntax of function
+calls: SMIE will automatically allow any sequence of sexps, such as
+identifiers, balanced parentheses, or @code{begin ... end} blocks
+to appear anywhere anyway.
+@item
+The grammar category @code{id} has no right hand side: this does not
+mean that it can match only the empty string, since as mentioned any
+sequence of sexps can appear anywhere anyway.
+@item
+Because non terminals cannot appear consecutively in the BNF grammar, it
+is difficult to correctly handle tokens that act as terminators, so the
+above grammar treats @code{";"} as a statement @emph{separator} instead,
+which SMIE can handle very well.
+@item
+Separators used in sequences (such as @code{","} and @code{";"} above)
+are best defined with BNF rules such as @code{(foo (foo "separator" foo) ...)}
+which generate precedence conflicts which are then resolved by giving
+them an explicit @code{(assoc "separator")}.
+@item
+The @code{("(" exps ")")} rule was not needed to pair up parens, since
+SMIE will pair up any characters that are marked as having paren syntax
+in the syntax table.  What this rule does instead (together with the
+definition of @code{exps}) is to make it clear that @code{","} should
+not appear outside of parentheses.
+@item
+Rather than have a single @emph{precs} table to resolve conflicts, it is
+preferable to have several tables, so as to let the BNF part of the
+grammar specify relative precedences where possible.
+@item
+Unless there is a very good reason to prefer @code{left} or
+@code{right}, it is usually preferable to mark operators as associative,
+using @code{assoc}.  For that reason @code{"+"} and @code{"*"} are
+defined above as @code{assoc}, although the language defines them
+formally as left associative.
+@end itemize
+
+@node SMIE Lexer
+@subsubsection Defining Tokens
+
+SMIE comes with a predefined lexical analyzer which uses syntax tables
+in the following way: any sequence of characters that have word or
+symbol syntax is considered a token, and so is any sequence of
+characters that have punctuation syntax.  This default lexer is
+often a good starting point but is rarely actually correct for any given
+language.  For example, it will consider @code{"2,+3"} to be composed
+of 3 tokens: @code{"2"}, @code{",+"}, and @code{"3"}.
+
+To describe the lexing rules of your language to SMIE, you need
+2 functions, one to fetch the next token, and another to fetch the
+previous token.  Those functions will usually first skip whitespace and
+comments and then look at the next chunk of text to see if it
+is a special token.  If so it should skip the token and
+return a description of this token.  Usually this is simply the string
+extracted from the buffer, but it can be anything you want.
+For example:
+@example
+@group
+(defvar sample-keywords-regexp
+  (regexp-opt '("+" "*" "," ";" ">" ">=" "<" "<=" ":=" "=")))
+@end group
+@group
+(defun sample-smie-forward-token ()
+  (forward-comment (point-max))
+  (cond
+   ((looking-at sample-keywords-regexp)
+    (goto-char (match-end 0))
+    (match-string-no-properties 0))
+   (t (buffer-substring-no-properties
+       (point)
+       (progn (skip-syntax-forward "w_")
+              (point))))))
+@end group
+@group
+(defun sample-smie-backward-token ()

+
+Notice how those lexers return the empty string when in front of
+parentheses.  This is because SMIE automatically takes care of the
+parentheses defined in the syntax table.  More specifically if the lexer
+returns nil or an empty string, SMIE tries to handle the corresponding
+text as a sexp according to syntax tables.
+
+@node SMIE Tricks
+@subsubsection Living With a Weak Parser
+
+The parsing technique used by SMIE does not allow tokens to behave
+differently in different contexts.  For most programming languages, this
+manifests itself by precedence conflicts when converting the
+BNF grammar.
+
+Sometimes, those conflicts can be worked around by expressing the
+grammar slightly differently.  For example, for Modula-2 it might seem
+natural to have a BNF grammar that looks like this:
+
+@example
+  ...
+  (inst ("IF" exp "THEN" insts "ELSE" insts "END")
+        ("CASE" exp "OF" cases "END")
+        ...)
+  (cases (cases "|" cases) (caselabel ":" insts) ("ELSE" insts))
+  ...
+@end example
+
+But this will create conflicts for @code{"ELSE"}: on the one hand, the
+IF rule implies (among many other things) that @code{"ELSE" = "END"};
+but on the other hand, since @code{"ELSE"} appears within @code{cases},
+which appears left of @code{"END"}, we also have @code{"ELSE" > "END"}.
+We can solve the conflict either by using:
+@example
+  ...
+  (inst ("IF" exp "THEN" insts "ELSE" insts "END")
+        ("CASE" exp "OF" cases "END")
+        ("CASE" exp "OF" cases "ELSE" insts "END")
+        ...)
+  (cases (cases "|" cases) (caselabel ":" insts))
+  ...
+@end example
+or
+@example
+  ...
+  (inst ("IF" exp "THEN" else "END")
+        ("CASE" exp "OF" cases "END")
+        ...)
+  (else (insts "ELSE" insts))
+  (cases (cases "|" cases) (caselabel ":" insts) (else))
+  ...
+@end example
+
+Reworking the grammar to try and solve conflicts has its downsides, tho,
+because SMIE assumes that the grammar reflects the logical structure of
+the code, so it is preferable to keep the BNF closer to the intended
+abstract syntax tree.
+
+Other times, after careful consideration you may conclude that those
+conflicts are not serious and simply resolve them via the
+@var{resolvers} argument of @code{smie-bnf->prec2}.  Usually this is
+because the grammar is simply ambiguous: the conflict does not affect
+the set of programs described by the grammar, but only the way those
+programs are parsed.  This is typically the case for separators and
+associative infix operators, where you want to add a resolver like
+@code{'((assoc "|"))}.  Another case where this can happen is for the
+classic @emph{dangling else} problem, where you will use @code{'((assoc
+"else" "then"))}.  It can also happen for cases where the conflict is
+real and cannot really be resolved, but it is unlikely to pose a problem
+in practice.
+
+Finally, in many cases some conflicts will remain despite all efforts to
+restructure the grammar.  Do not despair: while the parser cannot be
+made more clever, you can make the lexer as smart as you want.  So, the
+solution is then to look at the tokens involved in the conflict and to
+split one of those tokens into 2 (or more) different tokens.  E.g. if
+the grammar needs to distinguish between two incompatible uses of the
+token @code{"begin"}, make the lexer return different tokens (say
+@code{"begin-fun"} and @code{"begin-plain"}) depending on which kind of
+@code{"begin"} it finds.  This pushes the work of distinguishing the
+different cases to the lexer, which will thus have to look at the
+surrounding text to find ad-hoc clues.
+
+@node SMIE Indentation
+@subsubsection Specifying Indentation Rules
+
+Based on the provided grammar, SMIE will be able to provide automatic
+indentation without any extra effort.  But in practice, this default
+indentation style will probably not be good enough.  You will want to
+tweak it in many different cases.
+
+SMIE indentation is based on the idea that indentation rules should be
+as local as possible.  To this end, it relies on the idea of
+@emph{virtual} indentation, which is the indentation that a particular
+program point would have if it were at the beginning of a line.
+Of course, if that program point is indeed at the beginning of a line,
+its virtual indentation is its current indentation.  But if not, then
+SMIE uses the indentation algorithm to compute the virtual indentation
+of that point.  Now in practice, the virtual indentation of a program
+point does not have to be identical to the indentation it would have if
+we inserted a newline before it.  To see how this works, the SMIE rule
+for indentation after a @code{@{} in C does not care whether the
+@code{@{} is standing on a line of its own or is at the end of the
+preceding line.  Instead, these different cases are handled in the
+indentation rule that decides how to indent before a @code{@{}.
+
+Another important concept is the notion of @emph{parent}: The
+@emph{parent} of a token, is the head token of the nearest enclosing
+syntactic construct.  For example, the parent of an @code{else} is the
+@code{if} to which it belongs, and the parent of an @code{if}, in turn,
+is the lead token of the surrounding construct.  The command
+@code{backward-sexp} jumps from a token to its parent, but there are
+some caveats: for @emph{openers} (tokens which start a construct, like
+@code{if}), you need to start with point before the token, while for
+others you need to start with point after the token.
+@code{backward-sexp} stops with point before the parent token if that is
+the @emph{opener} of the token of interest, and otherwise it stops with
+point after the parent token.
+
+SMIE indentation rules are specified using a function that takes two
+arguments @var{method} and @var{arg} where the meaning of @var{arg} and the
+expected return value depend on @var{method}.
+
+@var{method} can be:
+@itemize
+@item
+@code{:after}, in which case @var{arg} is a token and the function
+should return the @var{offset} to use for indentation after @var{arg}.
+@item
+@code{:before}, in which case @var{arg} is a token and the function
+should return the @var{offset} to use to indent @var{arg} itself.
+@item
+@code{:elem}, in which case the function should return either the offset
+to use to indent function arguments (if @var{arg} is the symbol
+@code{arg}) or the basic indentation step (if @var{arg} is the symbol
+@code{basic}).
+@item
+@code{:list-intro}, in which case @var{arg} is a token and the function
+should return non-@code{nil} if the token is followed by a list of
+expressions (not separated by any token) rather than an expression.
+@end itemize
+
+When @var{arg} is a token, the function is called with point just before
+that token.  A return value of nil always means to fallback on the
+default behavior, so the function should return nil for arguments it
+does not expect.
+
+@var{offset} can be:
+@itemize
+@item
+@code{nil}: use the default indentation rule.
+@item
+@code{(column . @var{column})}: indent to column @var{column}.
+@item
+@var{number}: offset by @var{number}, relative to a base token which is
+the current token for @code{:after} and its parent for @code{:before}.
+@end itemize
+
+@node SMIE Indentation Helpers
+@subsubsection Helper Functions for Indentation Rules
+
+SMIE provides various functions designed specifically for use in the
+indentation rules function (several of those functions break if used in
+another context).  These functions all start with the prefix
+@code{smie-rule-}.
+
+@defun smie-rule-bolp
+Return non-@code{nil} if the current token is the first on the line.
+@end defun
+
+@defun smie-rule-hanging-p
+Return non-@code{nil} if the current token is @emph{hanging}.
+A token is @emph{hanging} if it is the last token on the line
+and if it is preceded by other tokens: a lone token on a line is not
+hanging.
+@end defun
+
+@defun smie-rule-next-p &rest tokens
+Return non-@code{nil} if the next token is among @var{tokens}.
+@end defun
+
+@defun smie-rule-prev-p &rest tokens
+Return non-@code{nil} if the previous token is among @var{tokens}.
+@end defun
+
+@defun smie-rule-parent-p &rest parents
+Return non-@code{nil} if the current token's parent is among @var{parents}.
+@end defun
+
+@defun smie-rule-sibling-p
+Return non-nil if the current token's parent is actually a sibling.
+This is the case for example when the parent of a @code{","} is just the
+previous @code{","}.
+@end defun
+
+@defun smie-rule-parent &optional offset
+Return the proper offset to align the current token with the parent.
+If non-@code{nil}, @var{offset} should be an integer giving an
+additional offset to apply.
+@end defun
+
+@defun smie-rule-separator method
+Indent current token as a @emph{separator}.
+
+By @emph{separator}, we mean here a token whose sole purpose is to
+separate various elements within some enclosing syntactic construct, and
+which does not have any semantic significance in itself (i.e. it would
+typically not exist as a node in an abstract syntax tree).
+
+Such a token is expected to have an associative syntax and be closely
+tied to its syntactic parent.  Typical examples are @code{","} in lists
+of arguments (enclosed inside parentheses), or @code{";"} in sequences
+of instructions (enclosed in a @code{@{...@}} or @code{begin...end}
+block).
+
+@var{method} should be the method name that was passed to
+`smie-rules-function'.
+@end defun
+
+@node SMIE Indentation Example
+@subsubsection Sample Indentation Rules
+
+Here is an example of an indentation function:
+
+@example
+(defun sample-smie-rules (kind token)
+  (pcase (cons kind token)
+    (`(:elem . basic) sample-indent-basic)
+    (`(,_ . ",") (smie-rule-separator kind))
+    (`(:after . ":=") sample-indent-basic)
+    (`(:before . ,(or `"begin" `"(" `"@{")))
+     (if (smie-rule-hanging-p) (smie-rule-parent)))
+    (`(:before . "if")
+     (and (not (smie-rule-bolp)) (smie-rule-prev-p "else")
+          (smie-rule-parent)))))
+@end example
+
+@noindent
+A few things to note:
+
+@itemize
+@item
+The first case indicates the basic indentation increment to use.
+If @code{sample-indent-basic} is nil, then SMIE uses the global
+setting @code{smie-indent-basic}.  The major mode could have set
+@code{smie-indent-basic} buffer-locally instead, but that
+is discouraged.
+
+@item
+The rule for the token @code{","} make SMIE try to be more clever when
+the comma separator is placed at the beginning of lines.  It tries to
+outdent the separator so as to align the code after the comma; for
+example:
+
+@example
+x = longfunctionname (
+        arg1
+      , arg2
+    );
+@end example
+
+@item
+The rule for indentation after @code{":="} exists because otherwise
+SMIE would treat @code{":="} as an infix operator and would align the
+right argument with the left one.
+
+@item
+The rule for indentation before @code{"begin"} is an example of the use
+of virtual indentation:  This rule is used only when @code{"begin"} is
+hanging, which can happen only when @code{"begin"} is not at the
+beginning of a line.  So this is not used when indenting
+@code{"begin"} itself but only when indenting something relative to this
+@code{"begin"}.  Concretely, this rule changes the indentation from:
+
+@example
+    if x > 0 then begin
+            dosomething(x);
+        end
+@end example
+to
+@example
+    if x > 0 then begin
+        dosomething(x);
+    end
+@end example
+
+@item
+The rule for indentation before @code{"if"} is similar to the one for
+@code{"begin"}, but where the purpose is to treat @code{"else if"}
+as a single unit, so as to align a sequence of tests rather than indent
+each test further to the right.  This function does this only in the
+case where the @code{"if"} is not placed on a separate line, hence the
+@code{smie-rule-bolp} test.
+
+If we know that the @code{"else"} is always aligned with its @code{"if"}
+and is always at the beginning of a line, we can use a more efficient
+rule:
+@example
+((equal token "if")
+ (and (not (smie-rule-bolp)) (smie-rule-prev-p "else")
+      (save-excursion
+        (sample-smie-backward-token)  ;Jump before the "else".
+        (cons 'column (current-column)))))
+@end example
+
+The advantage of this formulation is that it reuses the indentation of
+the previous @code{"else"}, rather than going all the way back to the
+first @code{"if"} of the sequence.
