+
+@subsection general-description DESCRIPTION
+
+The mdatabase_load () function returns the data specified by tags in
+the form of plist if the first tag is not @c Mchartable nor @c
+Mcharset.  The keys of the returned plist are limited to
+<tt>Minteger</tt>, <tt>Msymbol</tt>, <tt>Mtext</tt>, and
+<tt>Mplist</tt>.  The type of the value is unambiguously determined by
+the corresponding key.  If the key is <tt>Minteger</tt>, the value is
+an integer.  If the key is <tt>Msymbol</tt>, the value is a symbol.
+And so on.
+
+A number of expressions are possible to represent a plist.  For
+instance, we can use the form <tt>(K1:V1, K2:V2, ..., Kn:Vn)</tt> to
+represent a plist whose first property key and value are K1 and V1,
+second key and value are K2 and V2, and so on.  However, we can use a
+simpler expression here because the types of plists used in the m17n
+database are fairly restricted.
+
+Hereafter, we use an expression, which is similar to S-expression, to
+represent a plist.  (Actually, the default database loader of the m17n
+library is designed to read data files written in this expression.)
+
+The expression consists of one or more <i>elements</i>.  Each element
+represents a property, i.e. a single element of a plist.
+
+Elements are separated by one or more <i>whitespaces</i>, i.e. a space
+(code 32), a tab (code 9), or a newline (code 10).  Comments begin
+with a semicolon (<tt>;</tt>) and extend to the end of the line.
+
+The key and the value of each property are determined based on the
+type of the element as explained below.
+
+<ul>
+
+<li> INTEGER
+
+An element that matches the regular expression <tt>-?[0-9]+</tt> or
+<tt>0[xX][0-9A-Fa-f]+</tt> represents a property whose key is
+<tt>Minteger</tt>.  An element matching the former expression is
+interpreted as an integer in decimal notation, and one matching the
+latter is interpreted as an integer in hexadecimal notation.  The
+value of the property is the result of interpretation.
+
+For instance, the element <tt>0xA0</tt> represents a property whose
+value is 160 in decimal.
+
+<li> SYMBOL
+
+An element that matches the regular expression
+<tt>[^-0-9(]([^\\()]|\\.)+</tt> represents a property whose key is
+<tt> Msymbol</tt>.  In the element, <tt>\\t</tt>, <tt>\\n</tt>,
+<tt>\\r</tt>, and <tt>\\e</tt> are replaced with tab (code 9), newline
+(code 10), carriage return (code 13), and escape (code 27)
+respectively.  Other characters following a backslash is interpreted
+as it is.  The value of the property is the symbol having the
+resulting string as its name.
+
+For instance, the element <tt>abc\ def</tt> represents a property
+whose value is the symbol having the name "abc def".
+
+<li> MTEXT
+
+An element that matches the regular expression <tt>"([^"]|\\")*"</tt>
+represents a property whose key is <tt>Mtext</tt>.  The backslash
+escape explained above also applies here.  Moreover, each part in the
+element matching the regular expression <tt>
+\\[xX][0-9A-Fa-f][0-9A-Fa-f]</tt> is replaced with its hexadecimal
+interpretation.
+
+After having resolved the backslash escapes, the byte sequence between
+the double quotes is interpreted as a UTF-8 sequence and decoded into
+an M-text.  This M-text is the value of the property.
+
+<li> PLIST
+
+Zero or more elements surrounded by a pair of parentheses represent a
+property whose key is <tt>Mplist</tt>.  Whitespaces before and after a
+parenthesis can be omitted.  The value of the property is a plist,
+which is the result of recursive interpretation of the elements
+between the parentheses.
+
+</ul>
+
+@subsection general-syntax SYNTAX NOTATION
+
+In an explanation of a plist format of data, a BNF-like notation is
+used.  In the notation, non-terminals are represented by a string of
+uppercase letters (including '-' in the middle), terminals are
+represented by a string surrounded by '"'.  Special non-terminals
+INTEGER, SYMBOL, MTEXT and PLIST represents property integer, symbol,
+M-text, or plist respectively.
+
+@subsection general-example EXAMPLE
+
+Here is an example of database data that is read into a plist of this
+simple format:
+
+@verbatim
+DATA-FORMAT ::=
+    [ INTEGER | SYMBOL | MTEXT | FUNC ] *
+
+FUNC ::=
+    '(' FUNC-NAME FUNC-ARG * ')'
+
+FUNC-NAME ::=
+    SYMBOL
+
+FUNC-ARG ::=
+    INTEGER | SYMBOL | MTEXT | '(' FUNC-ARG ')'
+@endverbatim
+
+For instance, a data file that contains this text matches the above
+syntax:
+
+@verbatim
+abc 123 (pqr 0xff) "m\"text" (_\\_ ("string" xyz) -456)
+@endverbatim
+
+and is read into this plist:
+
+@verbatim
+1st element: key: Msymbol,  value: abc
+2nd element: key: Minteger, value: 123
+3rd element: key: Mplist,   value: a plist of these elements:
+    1st element: key Msymbol,  value: pgr
+    2nd element: key Minteger, value: 255
+4th element: key: Mtext,    value: m"text
+5th element: key: Mplist,   value: a plist of these elements:
+    1st element: key: Msymbol, value: _\_
+    2nd element: key: Mplist,  value: a plist of these elements:
+        1st element: key: Mtext,    value: string
+       2nd element: key: Msymbol,  value: xyz

+@section mdbFLT Font Layout Table
+
+@subsection flt-description DESCRIPTION
+
+For simple scripts, the rendering engine converts character codes into glyph
+codes one by one by consulting the encoding of each selected font.
+But, to render text that requires complicated layout (e.g. Thai and
+Indic scripts), one to one conversion is not sufficient.  A sequence
+of characters may have to be drawn as a single ligature.  Some
+glyphs may have to be drawn at 2-dimensionally shifted positions.
+
+To handle those complicated scripts, the m17n library uses Font Layout
+Tables (FLTs for short).  The FLT driver interprets an FLT and
+converts a character sequence into a glyph sequence that is ready to
+be passed to the rendering engine.
+
+An FLT can contain information to extract a grapheme cluster from a
+character sequence and to reorder the characters in the cluster, in
+addition to information found in OpenType Layout Tables (CMAP, GSUB,
+and GPOS).
+
+An FLT is a cascade of one or more conversion stages.  In each stage, a
+sequence is converted into another sequence to be read in the
+next stage.  The length of sequences may differ from stage to
+stage.  Each element in a sequence has the following integer attributes.
+
+<ul>
+<li> code
+
+In the first conversion stage, this is the character code in the
+original character sequence.  In the last stage, it is the glyph code
+passed to the rendering engine.  In other cases, it is an intermediate
+glyph code.
+
+<li> category
+
+This is the category code defined in the @c CATEGORY-TABLE
+of the current stage.
+
+<li> combining-spec
+
+If nonzero, it specifies how to combine this (intermediate) glyph
+with the previous one.
+
+<li> left-padding-flag
+
+If nonzero, it instructs the rendering function to insert a padding
+space before this (intermediate) glyph so that the glyph does not
+overlap with the previous one.
+
+<li> right-padding-flag
+
+If nonzero, it instructs the rendering function to insert a padding
+space after this (intermediate) glyph so that the glyph does not
+overlap with the next one.
+
+</ul>
+
+When the layout engine draws text, it at first determines a font and
+an FLT for each character in the text.  For each subsequence of
+characters that use use the same font and FLT, the layout engine
+generates an intermediate glyph sequence from the character
+subsequence.  Each element in the intermediate glyph sequence
+has the corresponding character code as the code attribute and zeroes
+for other attributes.  This sequence is processed in the
+first stage of FLT as the current @e run (substring).
+
+Each stage works as follows.
+
+At first, if the stage has a @c CATEGORY-TABLE, the category of each glyph
+in the current run is updated.  If there is a glyph that has no category,
+the current run ends before that glyph.
+
+Then, the default values of code-offset, combining-spec, and left-padding-flag
+of this stage are initialized to zero.
+
+Next, the initial conversion rule of the stage is applied to the
+current run.
+
+Lastly, the current run is replaced with the newly produced
+(intermediate) glyph sequence.
+
+@subsection flt-syntax SYNTAX and SEMANTICS
+
+The m17n library loads an FLT from the m17n database using the tag
+\<font, layouter, FLT-NAME\>.  The date format of an FLT is as follows:
+
+@verbatim
+FONT-LAYOUT-TABLE ::= STAGE0 STAGE *
+
+STAGE0 ::= CATEGORY-TABLE GENERATOR
+
+STAGE ::= CATEGORY-TABLE ? GENERATOR
+
+CATEGORY-TABLE ::= '(' 'category' CATEGORY-SPEC + ')'
+
+CATEGORY-SPEC ::= '(' CODE CATEGORY ')'
+                  | '(' CODE CODE CATEGORY ')'
+
+CODE ::= INTEGER
+
+CATEGORY ::= INTEGER
+@endverbatim
+
+In the definition of @c CATEGORY-SPEC, @c CODE is a glyph code, and @c
+CATEGORY is ASCII code of an upper or lower letter, i.e. one of 'A',
+... 'Z', 'a', .. 'z'.
+
+The first form of @c CATEGORY-SPEC assigns @c CATEGORY to a glyph
+whose code @c CODE.  The second form assigns @c CATEGORY to glyphs
+whose code falls between the two @c CODEs.
+
+@verbatim
+GENERATOR ::= '(' 'generator' RULE MACRO-DEF * ')'
+
+RULE ::= REGEXP-BLOCK | MATCH-BLOCK | SUBST-BLOCK | COND-BLOCK
+         | DIRECT-CODE | COMBINING-SPEC | OTF-SPEC
+         | PREDEFINED-RULE | MACRO-NAME
+
+MACOR-DEF ::= '(' MACRO-NAME RULE + ')'
+@endverbatim
+
+Each @c RULE specifies glyphs to be consumed and glyphs to be produced.  When
+some glyphs are consumed, they are taken away from the current run.  A
+rule may fail in some condition.  If not described explicitly to
+fail, it should be regarded that the rule succeeds.
+
+@verbatim
+DIRECT-CODE ::= INTEGER
+@endverbatim
+
+This rule consumes no glyph and produces a glyph which has the
+following attributes:
+
+<ul>
+<li> code : @c INTEGER plus the default code-offset
+<li> combining-spec : default value
+<li> left-padding-flag : default value
+<li> right-padding-flag : zero
+</ul>
+
+After having produced the glyph, the default code-offset,
+combining-spec, and left-padding-flag are all reset to zero.
+
+@verbatim
+PREDEFINED-RULE ::= '=' | '*' | '<' | '>' | '|' | '[' | ']'
+@endverbatim
+
+They perform actions as follows.
+
+<ul>
+<li> @c =
+
+This rule consumes the first glyph in the current run and produces the
+same glyph.  It fails if the current run is empty.
+
+<li> @c *
+
+This rule repeatedly executes the previous rule.
+If the previous rule fails, this rule does nothing and fails.
+
+<li> @c @<
+
+This rule specifies the start of a grapheme cluster.
+
+<li> @c @>
+
+This rule specifies the end of a grapheme cluster.
+
+<li> @c @[
+
+This rule sets the default left-padding-flag to 1.
+No glyph is consumed.  No glyph is produced.
+
+<li> @c @]
+
+This rule changes the right-padding-flag of the lastly generated
+glyph to 1.
+No glyph is consumed.  No glyph is produced.
+
+<li> @c |
+
+This rule consumes no glyph and produces a special glyph whose
+category is ' ' and other attributes are zero.  
+This is the only rule that produces that special glyph.
+
+</ul>
+
+@verbatim
+REGEXP-BLOCK ::= '(' REGEXP RULE * ')'
+
+REGEXP ::= MTEXT
+@endverbatim
+
+@c MTEXT is a regular expression that should match the sequence of
+categories of the current run.  If a match is found, this rule
+executes @c RULEs temporarily limiting the current run to the matched
+part.  The matched part is consumed by this rule.
+
+Parenthesized subexpressions, if any, are recorded to be used in @c
+MATCH-BLOCK that may appear in one of @c RULEs.
+
+If no match is found, this rule fails.
+
+@verbatim
+MATCH-BLOCK ::= '(' MATCH-INDEX RULE * ')'
+
+MATCH-INDEX ::= INTEGER
+@endverbatim
+
+@c MATCH-INDEX is an integer specifying a parenthesized subexpression
+recorded by the previous @c REGEXP-BLOCK.  If such a subexpression was
+found by the previous regular expression matching, this rule executes @c
+RULEs temporarily limiting the current run to the matched part
+of the subexpression.  The matched part is consumed by this rule.
+
+If no match was found, this rule fails.
+
+If this is the first rule of the stage, @c MATCH-INDEX must be 0, and
+it matches the whole current run.
+
+@verbatim
+SUBST-BLOCK ::= '(' SOURCE-PATTERN RULE * ')'
+
+SOURCE-PATTERN ::= '(' CODE + ')'
+                   | (' 'range' CODE CODE ')'
+@endverbatim
+
+If the sequence of codes of the current run matches @c SOURCE-PATTERN,
+this rule executes @c RULEs temporarily limiting the current run to
+the matched part.  The matched part is consumed.
+
+The first form of @c SOURCE-PATTERN specifies a sequence of glyph codes to be
+matched.  In this case, this rule resets the default code-offset to
+zero.
+
+The second form specifies a range of codes that should match the first
+glyph code of the code sequence.  In this case, this rule sets the
+default code-offset to the first glyph code minus the first @c CODE
+specifying the range.
+
+
+If no match is found, this rule fails.
+
+@verbatim
+COND-BLOCK ::= '(' 'cond' RULE + ')'
+@endverbatim
+
+This rule sequentially executes @c RULEs until one succeeds.  If no
+rule succeeds, this rule fails.  Otherwise, it succeeds.
+
+@verbatim
+OTF-SPEC ::= SYMBOL
+@endverbatim
+
+@c OTF-SPEC is a symbol whose name specifies an instruction to the OTF
+driver.  The name has the following syntax.
+
+@verbatim
+  OTF-SPEC-NAME ::= 'otf:' SCRIPT LANGSYS ? GSUB-FEATURES ? GPOS-FEATURES ?
+
+  SCRIPT ::= SYMBOL
+
+  LANGSYS ::= '/' SYMBOL
+
+  GSUB-FEATURES ::= '=' FEATURE-LIST ?
+
+  GPOS-FEATURES ::= '+' FEATURE-LIST ?
+
+  FEATURE-LIST ::= ( SYMBOL ',' ) * [ SYMBOL | '*' ]
+
+@endverbatim
+
+Each @c SYMBOL specifies a tag name defined in the OpenType
+specification.
+
+For @c SCRIPT, @c SYMBOL specifies a Script tag name (e.g. deva for
+Devanagari).
+
+For @c LANGSYS, @c SYMBOL specifies a Language System tag name.  If @c
+LANGSYS is omitted, the Default Language System
+table is used.
+
+For @c GSUB-FEATURES, each @c SYMBOL in @c FEATURE LIST specifies a GSUB Feature tag name
+to apply.  '*' is allowed as the last item to specify all remaining
+features.  If @c SYMBOL is preceded by '~' and the last item is '*',
+@c SYMBOL is excluded from the features to apply.  If no @c SYMBOL is
+specified, no GSUB feature is applied.  If @c GSUB-FEATURES itself is
+omitted, all GSUB features are applied.
+
+The specification of @c GPOS-FEATURES is analogous to that of @c
+GSUB-FEATURES.
+
+Please note that all the tags above must be 4 ASCII printable characters.
+
+See the following page for the OpenType specification.\n
+    <http://www.microsoft.com/typography/otspec/default.htm>
+
+@verbatim
+COMBINING ::= SYMBOL
+@endverbatim
+
+@c COMBINING is a symbol whose name specifies how
+to combine the next glyph with the previous one.  This rule sets the
+default combining-spec to an integer code that is unique to the symbol
+name.  The name has the following syntax.
+
+@verbatim
+  COMBINING-NAME ::= VPOS HPOS OFFSET VPOS HPOS
+
+  VPOS ::= 't' | 'c' | 'b' | 'B'
+
+  HPOS ::= 'l' | 'c' | 'r'
+
+  OFFSET :: = '.' | XOFF | YOFF XOFF ?
+
+  XOFF ::= ('<' | '>') INTEGER ?
+
+  YOFF ::= ('+' | '-') INTEGER ?
+@endverbatim
+
+@c VPOS and @c HPOS specify the vertical and horizontal positions
+as described below.
+
+@verbatim
+                                POINT VPOS HPOS
+                                ----- ---- ----

+    |         |                 3     B    l
+    9   10   11 <---- center    4     B    c
+    |         |                 5     B    r
+  --3----4----5-- <-- baseline  6     b    l
+    |         |                 7     b    c
+    6----7----8 <---- bottom    8     b    r
+                                9     c    l
+    |    |    |                10     c    c
+  left center right            11     c    r
+@endverbatim
+
+The left figure shows 12 reference points of a glyph by numbers 0 to
+11.  The rectangle 0-6-8-2 is the bounding box of the glyph, the
+positions 3, 4, and 5 are on the baseline, 9 and 11 are on the center
+of the lines 0-6 and 2-8 respectively, 1, 10, 4, and 7 are on the
+center of the lines 1-2, 3-5, 9-11, and 6-8 respectively.
+
+The right table shows how those reference points are specified by a
+pair of @c VPOS and @c HPOS.
+
+The first @c VPOS and @c HPOS in the definition of @c COMBINING-NAME
+specify the
+reference point of the previous glyph, and the second @c VPOS and @c
+HPOS specify that of the next glyph.
+The next glyph is drawn so that these two reference points align.
+
+@c OFFSET specifies the way of alignment in detail.  If it is '.', the
+reference points are on the same position.
+
+@c XOFF specifies how much the X position of the reference point of
+the next glyph should be shifted to the right ('<') or left ('>') from
+the previous reference point.
+
+@c YOFF specifies how much the Y position of the reference point the
+next glyphshould be shifted upward ('+') or downward ('-') from the
+previous reference point.
+
+In both cases, @c INTEGER is the amount of shift expressed as a
+percentage of the font size, i.e., if @c INTEGER is 10, it means
+10% (1/10) of the font size.  If @c INTEGER is omitted, it is assumed that
+5 is specified.
+
+Once the next glyph is combined with the previous one, they
+are treated as a single combined glyph.
+
+@verbatim
+MACRO-NAME ::= SYMBOL
+@endverbatim
+
+@c MACRO-NAME is a symbol that appears in one of @c MACRO-DEF.  It is
+exapanded to the sequence of the correponding @c RULEs.
+
+@subsection flt-context-dependent CONTEXT DEPENDENT BEHAVIOR
+
+So far, it has been assumed that each sequence, which is drawn with a
+specific font, is context free, i.e. not affected by the glyphs
+preceding or following that sequence.  This is true when sequence S1
+is drawn with font F1 while the preceding sequence S0 unconditionally
+requires font F0.
+
+@verbatim
+  sequence                              S0      S1
+  currently used font                   F0      F1
+  usable font(s)                        F0      F1
+@endverbatim
+
+Sometimes, however, a clear separation of sequences is not possible.
+Suppose that the preceding sequence S0 can be drawn not only with F0
+but also with F1.
+
+@verbatim
+  sequence                              S0      S1
+  currently used font                   F0      F1
+  usable font(s)                        F0,F1   F1
+@endverbatim
+
+In this case, glyphs used to draw the preceding S0 may affect glyph
+generation of S1.  Therefore it is necessary to access information
+about S0, which has already been processed, when processing S1.
+Generation rules in the first stage (only in the first stage) accept a
+special regular expression to access already processed parts.
+
+@verbatim
+  "RE0 RE1"
+@endverbatim
+
+@c RE0 and @c RE1 are regular expressions that match the preceding
+sequence S0 and the following sequence S1, respectively.
+
+Pay attention to the space between the two regular expressions.  It
+represents the special category ' ' (see above).  Note that the
+regular expression above belongs to glyph generation rules using font
+F1, therefore not only RE1 but also RE0 must be expressed with the
+categories for F1.  This means when the preceding sequence S0 cannot
+be expressed with the categories for F1 (as in the first example
+above) generation rules having these patterns never match.

+
+@c FONT-SPEC is to specify properties of a font.  @c FOUNDRY to @c
+REGISTRY are symbols corresponding to #Mfoundry to #Mregistry property
+of a font.  See @ref m17nFont for the meaning of each property.
+
+For instance, this @c FONT-SPEC:
+
+@verbatim
+    (nil alice0\ lao iso8859-1)
+@endverbatim
+
+should be applied to all fonts whose family name is "alice0 lao", and
+registry is "iso8859-1".
+
+@c ENCODING is a symbol representing a charset.  A font matching @c
+FONT-SPEC supports all characters of the charset, and a character code
+is mapped to the corresponding glyph code of the font by this charset.
+
+@c REPERTORY is a symbol representing a charset or "nil".  Omitting it
+is the same as specifying @c ENCODING as @c REPERTORY.  If it is not
+"nil", the charset specifies the repertory of the font, i.e, which
+character it supports.  Otherwise, whether a specific character is
+supported by the font or not is asked to each font driver.
+
+For so called Unicode fonts (registry is "iso10646-1"), it is
+recommended to specify "nil" as @c REPERTORY because such fonts
+usually supports only a subset of Unicode characters.  */

+
+In some case, a font contains incorrect information about its size
+(typically in the case of a hacked TrueType font), which results in a
+bad text layout when such a font is used in combination with the other
+fonts.  To overcome this problem, the m17n library loads information

+@section mdbIM Input Method
+
+@subsection im-description DESCRIPTION
+
+The m17n library provides a driver for input methods that are
+dynamically loadable from the m17n database (see @ref m17nInputMethod
+@latexonly (P.\pageref{group__m17nInputMethod}) @endlatexonly).
+
+This section describes the data format that defines those input
+methods.
+
+@subsection im-format SYNTAX and SEMANTICS
+
+The following data format defines an input method.  The driver loads
+a definition from a file, a stream, etc.  A definitions is converted
+into the form of plist in the driver.
+
+@verbatim
+INPUT-METHOD ::= TITLE MAP-LIST MACRO-LIST ? MODULE-LIST ? STATE-LIST
+
+TITLE ::= '(' 'title' MTEXT ')'
+@endverbatim
+
+@c MTEXT is a text displayed on the screen when this input method is
+active.
+
+@verbatim
+MAP-LIST ::= '(' 'map' MAP * ')'
+
+MAP ::= '(' MAP-NAME RULE * ')'
+
+MAP-NAME ::= SYMBOL
+
+RULE ::= '(' KEYSEQ MAP-ACTION * ')'
+
+KEYSEQ ::= MTEXT | '(' [ SYMBOL | INTEGER ] * ')'
+@endverbatim
+
+@c SYMBOL in the definitions of @c MAP-NAME must not be @c t nor @c
+nil.
+
+@c MTEXT in the definition of @c KEYSEQ consists of characters that
+can be generated by a keyboard.  Therefore @c MTEXT usually contains
+only ASCII characters.  However, if the input method is intended to be
+used, for instance, with a West European keyboard, @c MTEXT may
+contain Latin-1 characters.
+
+@c SYMBOL in the definition of @c KEYSEQ must be the return value of
+the minput_event_to_key () function.
+
+@c INTEGER in the definition of @c KEYSEQ must be a valid character
+code.
+
+@verbatim
+MAP-ACTION ::= ACTION
+
+ACTION ::= INSERT | DELETE | SELECT | MOVE | MARK |
+           | SHOW | HIDE | PUSHBACK | UNDO | SHIFT | CALL
+          | SET | IF | '(' MACRO-NAME ')'
+
+PREDEFINED-SYMBOL ::=
+    '@0' | '@1' | '@2' | '@3' | '@4' |
+    '@5' | '@6' | '@7' | '@8' | '@9' |
+    '@<' | '@=' | '@>' | '@-' | '@+' | '@[' | '@]'
+@endverbatim
+@verbatim
+MACRO-LIST ::= '(' 'macro' MACRO * ')'
+
+MACRO ::= '(' MACRO-NAME MACRO-ACTION * ')'
+
+MACRO-NAME ::= SYMBOL
+
+MACRO-ACTION ::= ACTION
+@endverbatim
+@verbatim
+MODULE-LIST ::= '(' 'module' MODULE * ')'
+
+MODULE ::= '(' MODULE-NAME FUNCTION * ')'
+
+MODULE-NAME ::= SYMBOL
+
+FUNCTION ::= SYMBOL
+@endverbatim
+
+Each @c MODULE declares the name of external module (i.e. dynamic
+library) and function names exported by the module.  If a @c FUNCTION has
+name "init", it is called with only the default arguments (see the
+section about @c CALL) when an input context is created for the input
+method.  If a @c FUNCTION has name "fini", it is called with only the
+default arguments when an input context is destroyed.
+
+@verbatim
+STATE-LIST ::= '(' 'state' STATE * ')'
+
+STATE ::= '(' STATE-NAME BRANCH * ')'
+
+STATE-NAME ::= SYMBOL
+
+BRANCH ::= '(' MAP-NAME BRANCH-ACTION * ')'
+          | '(' nil BRANCH-ACTION * ')'
+          | '(' t BRANCH-ACTION * ')'
+@endverbatim
+
+In the first form of @c BRANCH, @c MAP-NAME must be an item that appears
+in @c MAP.  In this case, if a key sequence matching one of @c
+KEYSEQs of @c MAP-NAME is typed, @c BRANCH-ACTIONs are executed.
+
+In the second form of @c BRANCH, @c BRANCH-ACTIONs are executed if a
+key sequence that doesn't match any of @c Branch's of the current
+state is typed.
+
+In the third form of @c BRANCH, @c BRANCH-ACTIONs are executed if we
+shift to the current state after handling all typed keys.  If the
+current state is the initial state, @c BRANCH-ACTIONs are executed
+just after an input context of the input method is created.
+
+@verbatim
+BRANCH-ACTION ::= ACTION
+@endverbatim
+
+An input method has the following two lists of symbols.
+
+<ul>
+<li> marker list
+
+A marker is a symbol indicating a character position in the preediting
+text.  The @c MARK action assigns a position to a marker.  The
+position of a marker is referred by the @c MOVE and the @c DELETE actions.
+
+<li> variable list
+
+A variable is a symbol associated with an integer value.  The value of
+a variable is set by the @c SET action, and is referred by the @c SET,
+the @c INSERT, and the @c IF actions.  All variables are implicitly
+initialized to zero.
+
+</ul>
+
+Each @c PREDEFINED-SYMBOL has a special meaning when used as a marker.
+
+<ul>
+<li> @c @@0, @c @@1, @c @@2, @c @@3, @c @@4, @c @@5, @c @@6, @c @@7, @c @@8, @c @@9
+
+The 0th, 1st, 2nd, ... 9th position respectively.
+
+<li> @c @@<, @c @@=, @c @@>
+
+The first, the current, and the last position.
+
+<li> @c @@-, @c @@+
+
+The previous and the next position.
+
+<li> @c @@[, @c @@]
+
+The previous and the next position where a candidate list changes.
+</ul>
+
+Some of the @c PREDEFINED-SYMBOL has a special meaning when used as a candidate
+index in the @c SELECT action.
+
+<ul>
+
+<li> @c @@<, @c @@=, @c @@>
+
+The first, the current, and the last candidate of the current candidate group.
+
+<li> @c @@-
+
+The previous candidate.  If the current candidate is the first one in
+the current candidate group, then it means the last candidate in the
+previous candidate group.
+
+<li> @c @@+
+
+The next candidate.  If the current candidate is the last one in the
+current candidate group, then it means the first candidate in the next
+candidate group.
+
+<li> @c @@[, @c @@]
+
+The candidate in the previous and the next candidate group having the same
+candidate index as the current one.
+</ul>
+
+The arguments and the behavior of each action are listed below.
+
+@verbatim
+INSERT ::= '(' 'insert' MTEXT ')'
+           | MTEXT
+          | INTEGER
+           | '(' 'insert' SYMBOL ')'
+           | '(' 'insert' '(' CANDIDATES * ')' ')'
+           | '(' CANDIDATES * ')' 
+
+CANDIDATES ::= MTEXT | '(' MTEXT * ')'
+@endverbatim
+
+The first and second forms insert @c MTEXT before the current position.
+
+The third form inserts the character @c INTEGER before the current
+position.
+
+The fourth form treats @c SYMBOL as a variable, and inserts its value
+(if it is a valid character code) before the current position.
+
+In the fifth and sixth forms, each @c CANDIDATES represents a
+candidate group, and each element of @c CANDIDATES represents a
+candidate, i.e. if @c CANDIDATES is an M-text, the candidates are the
+characters in the M-text; if @c CANDIDATES is a list of M-texts, the
+candidates are the M-texts in the list.
+
+These forms insert the first candidate before the current position.
+The inserted string is associated with the list of candidates and
+the information indicating the currently selected candidate.
+
+The marker positions affected by the insertion are automatically relocated.
+
+@verbatim
+DELETE ::= '(' 'delete' SYMBOL ')'
+           | '(' 'delete' INTEGER ')'
+@endverbatim
+
+The first form treats @c SYMBOL as a marker, and deletes characters
+between the current position and the marker position.
+
+The second form treats @c INTEGER as a character position, and deletes
+characters between the current position and the character position.
+
+The marker positions affected by the deletion are automatically relocated.
+
+@verbatim
+SELECT ::= '(' 'select' PREDEFINED-SYMBOL ')'
+           | '(' 'select' INTEGER ')'
+@endverbatim
+
+This action first checks if the character just before the current position
+belongs to a string that is associated with a candidate list.  If it is,
+the action replaces that string with a candidate specified by the
+argument.
+
+The first form treats @c PREDEFINED-SYMBOL as a candidate index (as
+described above) that specifies a new candidate in the candidate list.
+
+The second form treats @c INTEGER as a candidate index that specifies a
+new candidate in the candidate list.
+
+@verbatim
+SHOW ::= '(show)'
+@endverbatim
+
+This actions instructs the input method driver to display a candidate
+list associated with the string before the current position.
+
+@verbatim
+HIDE ::= '(hide)'
+@endverbatim
+
+This action instructs the input method driver to hide the currently
+displayed candidate list.
+
+@verbatim
+MOVE ::= '(' 'move' SYMBOL ')'
+         | '(' 'move' INTEGER ')'
+@endverbatim
+
+The first form treats @c SYMBOL as a marker, and makes the marker
+position be the new current position.
+
+The second form treats @c INTEGER as a character position, and makes
+that position be the new current position.
+
+@verbatim
+MARK ::= '(' 'mark' SYMBOL ')'
+@endverbatim
+
+This action treats @c SYMBOL as a marker, and sets its position to the
+current position.  @c SYMBOL must not be a @c PREDEFINED-SYMBOL.
+
+
+@verbatim
+PUSHBACK :: = '(pushback INTEGER)'
+@endverbatim
+
+This action pushes back the latest @c INTEGER number of key events to the event queue.
+
+@verbatim
+UNDO :: = '(undo)'
+@endverbatim
+
+This action cancels the last key event.
+
+@verbatim
+SHIFT :: = '(' 'shift' STATE-NAME ')'
+@endverbatim
+
+This action shifts the current state to @c STATE-NAME.  @c
+STATE-NAME must appear in @c STATE-LIST.
+
+@verbatim
+CALL ::= '(' 'call' MODULE-NAME FUNCTION ARG * ')'
+
+ARG ::= INTEGER | SYMBOL | MTEXT | PLIST
+@endverbatim
+
+This action calls the function @c FUNCTION of external module @c
+MODULE-NAME.  @c MODULE-NAME and @c FUNCTION must appear in @c
+MODULE-LIST.
+
+The function is called with an argument of the type (#MPlist *).  The
+key of the first element is #Mt and its value is a pointer to an
+object of the type #MInputContext.  The key of the second element is
+#Msymbol and its value is the current state name.  @c ARGs are used as
+the value of the third and later elements.  Their keys are determined
+automatically; if an @c ARG is an integer, the corresponding key is
+#Minteger; if an @c ARG is a symbol, the corresponding key is
+#Msymbol, etc.
+
+The function must return NULL or a value of the type (#MPlist *) that
+represents a list of actions to take.
+
+@verbatim
+SET ::= '(' OPERAND SYMBOL1 [ INTEGER | SYMBOL2 ] ')'
+
+OPERAND ::= 'set' | 'add' | 'sub' | 'mul' | 'div'
+@endverbatim
+
+This action treats @c SYMBOL1 and @c SYMBOL2 as variables and sets the
+value of @c SYMBOL1 as below.
+
+If @c OPERAND is 'set', it sets the value of @c SYMBOL1 to @c INTEGER or the
+value of @c SYMBOL2.
+
+If @c OPERAND is 'add', it increments the value of @c SYMBOL1 by @c INTEGER
+or the value of @c SYMBOL2.
+
+If @c OPERAND is 'sub', it decrements the value of @c SYMBOL1 by @c INTEGER
+or the value of @c SYMBOL2.
+
+If @c OPERAND is 'mul', it multiplies the value of @c SYMBOL1 by @c INTEGER
+or the value of @c SYMBOL2.
+
+If @c OPERAND is 'div', it divides the value of @c SYMBOL1 by @c INTEGER or
+the value of @c SYMBOL2.
+
+@verbatim
+IF ::= '(' CONDITION ACTION-LIST1 ACTION-LIST2 * ')'
+
+CONDITION ::= OPERAND VAL1 VAL2
+
+ACTION-LIST1 ::= '(' ACTION * ')'
+
+ACTION-LIST2 ::= '(' ACTION * ')'
+
+OPERAND ::= '=' '<' '>'
+
+VAL1 ::= [ INTEGER1 | SYMBOL1 ]
+
+VAL2 ::= [ INTEGER2 | SYMBOL2 ]
+@endverbatim
+
+This action performs actions in @c ACTION-LIST1 if @c CONDITION is
+true, and performs @c ACTION-LIST2 (if any) otherwise.
+
+@c SYMBOL1 and @c SYMBOL2 are treated as variables.

+@subsection im-example2 EXAMPLE 2
+
+This example is for inputting Unicode characters by typing C-u
+(Control-u) followed by four hexadecimal numbers.  For instance, when
+you type ("^u" means Control-u):
+@verbatim
+    ^u2190^u2191^u2192^u2193
+@endverbatim
+you will get this (Unicode arrow symbols):
+@verbatim
+    ←↑→↓
+@endverbatim
+
+The definition utilizes @c SET and @c IF commands as below:
+@verbatim
+(title "UNICODE")
+(map
+ (starter
+  ((C-U) "U+"))
+ (hex
+  ("0" ?0) ("1" ?1) ... ("9" ?9) ("a" ?A) ("b" ?B) ... ("f" ?F)))
