GNU LESSER GENERAL PUBLIC LICENSE - Version 2.1, February 1999 - - Copyright (C) 1991, 1999 Free Software Foundation, Inc. - 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - -[This is the first released version of the Lesser GPL. It also counts - as the successor of the GNU Library Public License, version 2, hence - the version number 2.1.] - - Preamble - - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. - - This license, the Lesser General Public License, applies to some -specially designated software packages--typically libraries--of the -Free Software Foundation and other authors who decide to use it. You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it becomes -a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, whereas the latter must -be combined with the library in order to run. - - GNU LESSER GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Lesser General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY -KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE -IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN -WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY -AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU -FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR -CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE -LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING -RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A -FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF -SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH -DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Libraries - - If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change.

The m17n library supports many predefined - coded character sets. Moreover, application programs can add - other charsets. A character can belong to multiple charsets. - - The m17n library distinguishes the following three concepts: - - @li A @e code-point is a number assigned by the CCS to each - character. Code-points may or may not be continuous. The type - @c unsigned is used to represent a code-point. An invalid - code-point is represented by the macro @c MCHAR_INVALID_CODE. - - @li A @e character @e index is the canonical index of a character - in a CCS. The character that has the character index N occupies - the Nth position when all the characters in the current CCS are - sorted by their code-points.

The m17n database contains multiple heterogeneous data, - and each data is identified by four tags; TAG1, TAG2, TAG3, TAG4. - Each tag must be a symbol. - - TAG1 specifies the type of data stored in the database as below. - -

If TAG1 is #Mchar_table, the data is of the @e chartable @e - type and provides information about each character. In this case, - TAG2 specifies the type of the information and must be #Msymbol, - #Minteger, #Mstring, #Mtext, or #Mplist. TAG3 and TAG4 can be any - symbols. - -
If TAG1 is #Mcharset, the data is of the @e charset @e type - and provides a decode/encode mapping table for a charset. In this - case, TAG2 must be a symbol representing a charset. TAG3 and TAG4 - can be any symbols. - -
If TAG1 is neither #Mchar_table nor #Mcharset, the data is of - the @e plist @e type. See the documentation of the mdatabase_load - () function for the details. In this case, TAG2, TAG3, and TAG4 - can be any symbols. - -

-    @brief Draw an M-text on a window.
-
-    The mdraw_text () function draws the text between $FROM and $TO of
-    M-text $MT on window $WIN of frame $FRAME at coordinate ($X, $Y).
-
-    The appearance of the text (size, style, color, etc) is specified
-    by the value of the text property whose key is @c Mface.  If the
-    M-text or a part of the M-text does not have such a text property,
-    the default face of $FRAME is used.
-
-    The font used to draw a character in the M-text is selected from
-    the value of the fontset property of a face by the following
-    algorithm:
-
-    
-
-     Search the text properties given to the character for the one
-	 whose key is @c Mcharset; its value should be either a symbol
-	 specifying a charset or Mnil.  If the value is Mnil, proceed
-	 to the next step.
-
-	 Otherwise, search the mapping table of the fontset for the
-	 charset.  If no entry is found proceed to the next step.  If
-	 an entry is found, use one of the fonts in the entry that has
-	 a glyph for the character and that matches best with the face
-	 properties.  If no such font exists, proceed to the next
-	 step.
-
-    
 Get the character-property script of the character.  If it is
-	 inherited, get the script property from the previous
-	 characters.  If there is no previous character, or none of
-	 them has the script property other than inherited, proceed to
-	 the next step.
-
-	 Search the text properties given to the character for the one
-         whose key is @c Mlanguage; its value should be either a
-         symbol specifying a language or @c Mnil.
-
-	 Search the mapping table of the fontset for the combination
-	 of the script and language.  If no entry is found, proceed to
-	 the next step.  If an entry is found, use one of the fonts in
-	 the entry that has a glyph for the character and that matches
-	 best with the face properties.  If no such font exists,
-	 proceed to the next step.
-
-    
 Search the fall-back table of the fontset for a font that has
-	 a glyph of the character.  If such a font is found, use that
-	 font.
-
-    
-
-    If no font is found by the algorithm above, this function draws an
-    empty box for the character.
-
-    This function draws only the glyph foreground.  To specify the
-    background color, use mdraw_image_text () or
-    mdraw_text_with_control ().
-
-    This function is the counterpart of XDrawString (),
-    XmbDrawString (), and XwcDrawString () functions
-    in the X Window System.
-
-    @return
-    If the operation was successful, mdraw_text () returns 0.  If an
-    error is detected, it returns -1 and assigns an error code to the
-    external variable @c merror_code.  */

-    @brief A face is an object to control appearance of M-text.
-
-    A @e face is an object of the type #MFace and controls how to
-    draw M-texts.  A face has a fixed number of @e face @e properties.
-    Like other types of properties, a face property consists of a key
-    and a value.  A key is one of the following symbols:
-
-    #Mforeground, #Mbackground, #Mvideomode, #Mhline, #Mbox,
-    #Mfoundry, #Mfamily, #Mweight, #Mstyle, #Mstretch, #Madstyle,
-    #Msize, #Mfontset, #Mratio, #Mhook_func, #Mhook_arg
-
-    "The face property that belongs to face F and whose key is @c xxx"
-    may be shortened to "the xxx property of F".
-
-    The M-text drawing functions first search an M-text for the text
-    property whose key is the symbol #Mface, then draw the M-text
-    using the value of that text property.  This value must be a
-    pointer to a face object.
-
-    If there are multiple text properties whose key is @c Mface, and
-    they are not conflicting one another, properties of those faces
-    are merged and used.
-
-    If no faces specify a certain property, the value of the default
-    face is used.  */

-    @brief Font object
-
-    The m17n GUI API represents a font by an object of the type @c
-    MFont.  A font can have @e font @e properties.  Like other types
-    of properties, a font property consists of a key and a value.  The
-    key of a font property must be one of the following symbols:
-
-    @c Mfoundry, @c Mfamily, @c Mweight, @c Mstyle, @c Mstretch,
-    @c Madstyle, @c Mregistry, @c Msize, @c Mresolution.
-
-    When the key of a font property is @c Msize or @c Mresolution, its
-    value is an integer.  Otherwise the value is a symbol.  "The font
-    property that belongs to font F and whose key is @c Mxxx" may be
-    shortened to "the xxx property of F".
-
-    The value of a foundry property is a symbol representing font
-    foundry information, e.g. adobe, misc, etc.
-
-    The value of a family property is a symbol representing font family
-    information, e.g. times, helvetica, etc.
-
-    The value of a weight property is a symbol representing weight
-    information, e.g. normal, bold, etc.
-
-    The value of a style property is a symbol representing slant
-    information, e.g. normal, italic, etc.
-
-    The value of a stretch property is a symbol representing width
-    information, e.g. normal, semicondensed, etc.
-
-    The value of an adstyle property is a symbol representing abstract
-    font family information, e.g. serif, sans-serif, etc.
-
-    The value of a registry property is a symbol representing registry
-    information, e.g. iso10646-1, iso8895-1, etc.
-
-    The value of a size property is an integer representing design
-    size in the unit of 1/10 point.
-
-    The value of a resolution property is an integer representing
-    assumed device resolution in the unit of dots per inch (dpi)
-
-    The m17n library uses font objects for two purposes: to receive
-    font specification from an application program, and to present
-    available fonts to an application program.  When the m17n library
-    presents an available font to an application program, all font
-    properties have a concrete value.
-
-    The m17n library supports three kinds of fonts: Window system fonts,
-    FreeType fonts, and OpenType fonts.
-
-    
-
-     Window system fonts
-
-    The m17n-X library supports all fonts handled by an X server and
-    an X font server.  The correspondence between XLFD fields and font
-    properties are shown below.
-
-@verbatim
-    XLFD field                                  property
-    ---------------                             --------
-    FOUNDRY                                     foundry
-    FAMILY_NAME                                 family
-    WEIGHT_NAME                                 weight
-    SLANT                                       style
-    SETWIDTH_NAME                               stretch
-    ADD_STYLE_NAME                              adstyle
-    POINT_SIZE                                  size
-    RESOLUTION_Y                                resolution
-    CHARSET_REGISTRY-CHARSET_ENCODING           registry
-@endverbatim
-
-    XLFD fields not listed in the above table are ignored.
-
-    
 FreeType fonts
-
-    The m17n library, if configured to use the FreeType library,
-    supports all fonts that can be handled by the FreeType library.
-    The variable #mfont_freetype_path is initialized properly accoding
-    to the configuration of the m17n librayr and the environment
-    variable @c M17NDIR.  See the documentation of the variable for
-    details.
-
-    The family name of a FreeType font corresponds to the family
-    property.  Style names of FreeType fonts correspond to the weight,
-    style, and stretch properties as below.
-
-@verbatim
-    style name          weight  style   stretch
-    ----------          ------  -----   -------
-    Regular             medium  r       normal
-    Italic              medium  i       normal
-    Bold                bold    r       normal
-    Bold Italic         bold    i       normal
-    Narrow              medium  r       condensed
-    Narrow Italic       medium  i       condensed
-    Narrow Bold         bold    r       condensed
-    Narrow Bold Italic  bold    i       condensed
-    Black               black   r       normal
-    Black Italic        black   i       normal
-@endverbatim
-
-    Style names not listed in the above table are treated as
-    "Regular".
-
-    Combination of a platform ID and an encoding ID corresponds to the
-    registry property.  For example, if a font has the combination (1
-    1), the registry property is 1-1.  Some frequent combinations have
-    a predefined registry property as below.
-
-@verbatim
-    platform ID         encoding ID     registry property
-    -----------         -----------     -----------------
-    0                   3               unicode-bmp
-    0                   4               unicode-full
-    1                   0               apple-roman
-    3                   1               unicode-bmp
-    3                   1               unicode-full
-@endverbatim
-
-    Thus, a font that has two combinations (1 0) and (3 1) corresponds
-    to four font objects whose registries are 1-0, apple-roman, 3-1,
-    and unicode-bmp.
-
-    
 OpenType fonts 
-
-    The m17n library, if configured to use both the FreeType library
-    and the OTF library, supports any OpenType fonts.  The list of
-    actually available fonts is created in the same way as in the case
-    of FreeType fonts.  If a fontset instructs to use an OpenType font
-    via an FLT (Font Layout Table), and the FLT has an OTF-related
-    command (e.g. otf:deva), the OTF library converts a character
-    sequence to a glyph code sequence according to the OpenType layout
-    tables of the font, and the FreeType library gives a bitmap image
-    for each glyph.

-    @brief Modify the contents of a fontset.
-
-    The mfontset_modify_entry () function associates, in $FONTSET, a
-    copy of $FONT with the $SCRIPT / $LANGUAGE pair or with $CHARSET.
-
-    Each font in a fontset is associated with a particular
-    script/language pair, with a particular charset, or with the
-    symbol @c Mnil.  The fonts that are associated with the same item
-    make a group.
-
-    If $SCRIPT is not @c Mnil, it must be a symbol identifying a
-    script.  In this case, $LANGUAGE is either a symbol identifying a
-    language or @c Mnil, and $FONT is associated with the $SCRIPT /
-    $LANGUAGE pair.
-
-    If $CHARSET is not @c Mnil, it must be a symbol representing a
-    charset object.  In this case, $FONT is associated with that
-    charset.
-
-    If both $SCRIPT and $CHARSET are not @c Mnil, two copies of $FONT
-    are created.  Then one is associated with the script/language pair
-    and the other with the charset.
-
-    If both $SCRIPT and $CHARSET are @c Mnil, $FONT is associated
-    with @c Mnil.  This kind of fonts are called fallback
-    fonts.
-
-    The argument $HOW specifies the priority of $FONT.  If $HOW is
-    positive, $FONT has the highest priority in the group of fonts
-    that are associated with the same item.  If $HOW is negative,
-    $FONT has the lowest priority.  If $HOW is zero, $FONT becomes the
-    only available font for the associated item; all the other fonts
-    are removed from the group.
-
-    If $LAYOUTER_NAME is not @c Mnil, it must be a symbol
-    representing a @ref flt.  In that case, if $FONT is selected for
-    drawing an M-text, that font layout table is used to generate a
-    glyph code sequence from a character sequence.
-
-    @return
-    If the operation was successful, mfontset_modify_entry () returns 0.
-    Otherwise it returns -1 and assigns an error code to the external
-    variable @c merror_code.  */

-    The input driver @c minput_gui_driver is provided for internal
-    input methods that is useful on window systems.  It displays
-    preedit text and status text at the inputting spot.  See the
-    documentation of @c minput_gui_driver for more detail.
-
-    In the m17n-X library, the foreign input method of name @c Mxim is
-    provided.  It uses XIM (X Input Method) as a background input
-    engine.  The symbol @c Mxim has a property @c Minput_driver whose
-    value is a pointer to the input driver @c minput_xim_driver.  See
-    the documentation of @c minput_xim_driver for more detail.  */

-    @brief Input driver for internal input methods on window systems.
-
-    The input driver @c minput_gui_driver is for internal input
-    methods to be used on window systems.
-
-    It creates sub-windows for a preedit text and a status text, and
-    displays them at the input spot set by the function
-    minput_set_spot ().
-
-    The function m17n_initialize_win () set the variable @c
-    minput_driver to the pointer to this driver so that all internal
-    input methods use it.
-
-    Therefore, unless @c minput_driver is changed from the default,
-    the driver dependent arguments to the functions whose name begin
-    with minput_ must are treated as follows.
-
-    The argument $ARG of the function minput_open_im () is ignored.
-
-    The argument $ARG of the function minput_create_ic () must be a
-    pointer to the structure @c MInputGUIArgIC.  See the documentation
-    of @c MInputGUIArgIC for more detail.
-
-    If the argument $KEY is @c Mnil, the argument $ARG of the
-    function minput_filter () must be a pointer to the object of type
-    @c XEvent.  In that case, $KEY is generated from $ARG.
-
-    The argument $ARG of the function minput_lookup () must be the
-    same one as that of the function minput_filter (). */

-
-    The minput_event_to_key () function returns the input key
-    corresponding to event $EVENT on $FRAME by a window system
-    dependent manner.
-
-    In the m17n-X library, $EVENT must be a pointer to the struct @c
-    XKeyEvent, and it is handled as below.
-
-    At first, the keysym name of $EVENT is acquired by the function @c
-    XKeysymToString.
-
-    Then, the name is modified as below.
-
-    If the name is one of "a" .. "z" and $EVENT has a Shift modifier,
-    the name is converted to "A" .. "Z" respectively, and the Shift
-    modifier is cleared.
-
-    If the name is one byte length and $EVENT has a Control modifier,
-    the byte is bitwise anded by 0x1F and the Control modifier is
-    cleared.
-
-    If $EVENT still has Shift, Control, Meta, Alt, Super, and/or Hyper
-    modifiers, the name is prepended by "S-", "C-", "M-", "A-", "s-",
-    and/or "H-" respectively in this order.
-
-    For instance, if the keysym name is "a" and the event has Shift,
-    Meta, and Hyper modifiers, the resulting name is "H-M-A".
-
-    At last, a symbol who has the name is returned.  */

-    @brief API for Input method
-
-    An input method is an object to enable inputting various
-    characters.  An input method is identified by a pair of symbols,
-    LANGUAGE and NAME.  This pair decides an input driver of the input
-    method.  An input driver is a set of functions for handling the
-    input method.  There are two kinds of input methods; internal one
-    and foreign one.
-
-    
-
-     Internal Input Method
-
-    An internal input method has non @c Mnil LANGUAGE, and the body is
-    defined in the m17n database by the tag .  For this kind of input methods, the m17n library uses two
-    predefined input method drivers, one for CUI use and the other for
-    GUI use.  Those driver utilize the input processing engine
-    provided by the m17n library itself.  The m17n database may
-    provides an input method that is not only for a specific language.
-    The database uses @c Mt as the language of such an input method.
-
-    An internal input method accepts an input key which is a symbol
-    associated with an input event.  As there is no way for the @c
-    m17n @c library to know how input events are represented in an
-    application program, a application programmer have to convert an
-    input event to an input key by himself.  See the documentation of
-    the function minput_event_to_key () for the detail.
-
-    
 Foreign Input Method
-
-    A foreign input method has @c Mnil LANGUAGE, and the body is
-    defined in an external resources (e.g. XIM of X Window System).
-    For this kind of input methods, the symbol NAME must have a
-    property of key @c Minput_driver, and the value must be a pointer
-    to an input driver.  So, by preparing a proper input 
-    driver, any kind of input method can be treated in the framework
-    of the @c m17n @c library.
-
-    For convenience, the m17n-X library provides an input driver that
-    enables the input style of OverTheSpot for XIM, and stores @c
-    Minput_driver property of the symbol @c Mxim with a pointer to
-    that driver.  See the documentation of m17n GUI API for the
-    detail.
-
-    
-
-    PROCESSING FLOW
-
-    The typical processing flow of handling an input method is: open
-    an input method, create an input context for the input method,
-    filter an input key, and looking up a produced text in the input
-    context.  */

-

-    can be shown to users.
-
-    The macro M17N_INIT () sets the variable #minput_driver to the
-    pointer to this driver so that all internal input methods use it.
-
-    Therefore, unless @c minput_driver is set differently, the driver
-    dependent arguments $ARG of the functions whose name begin with

-    @brief Introduction to the m17n library
-
-    API LEVELS
-
-    The API of the m17n library is divided into these four.
-
-    
-     CORE API
-
-    It provides basic modules to handle M-texts.  They don't require
-    the m17n database.  To use this API, an application program must
-    include  and be linked by -lm17n-core.
-
-    
 SHELL API
-
-    It provides modules that utilize the m17n database.  They load
-    various kinds of data from the database on demand.  To use this
-    API, an application program must include  and be linked by
-    -lm17n-core -lm17n.  With that, CORE API is also available.
-
-    
 GUI API
-
-    It provides GUI modules such as drawing and inputting M-texts on a
-    window system.  The API itself is independent on a window system,
-    but the m17n library must be configured to use a specific window
-    system.  Currently, we support only the X Window System.  To use
-    this API, an application program must include  and
-    , and be linked by -lm17n-core -lm17n -lm17n-X.  With
-    that, CORE and SHELL APIs are also available.
-
-    
 MISC API
-
-    It provides miscellaneous functions to support error handling and
-    debugging.  This API can't be used by itself, but with one or more
-    APIs listed above.  To use the API, an application program must
-    include  in addition to one of ,
-    , and .
-
-    
-
-    See also the section @ref m17n-config "m17n-config(1)".
-
-    ENVIRONMENT VARIABLE
-
-    The m17n library pays attention to these environment variables.
-
-    
-     @c M17NDIR
-
-    Name of a directory that contains data of the m17n database.  See
-    @ref m17nDatabase for the detail.
-
-    
 @c MDEBUG_XXXX
-
-    Environment variables whose name start by "MDEBUG_" controls
-    printing of debug information.  See @ref m17nDebug for the detail.
-
-    
-
-    API NAMING CONVENTION
-
-    The library exports functions, variables, macros, and types.  All
-    of them start by the letter 'm' or 'M' followed by an object name
-    (e.g. "symbol" and "plist", but "mtext" object is given the name
-    "text" to avoid double 'm' at the head) or a module name
-    (e.g. draw, input).
-    
-    
-
-     functions -- mobject () or mobject_xxx ()
-
-    They start with 'm' followed by lower case object name.  For
-    example, msymbol (), mtext_ref_char (), mdraw_text ().
-
-    
 non-symbol variables -- mobject, or mobject_xxx
-    
-    The naming convention is the same as functions (e.g. mface_large).
-
-    
 symbol variables -- Mname
-
-    Variables of type MSymbol start with 'M' followed by their names
-    (e.g. Mlanguage (name is "langauge"), Miso_2022 (name is
-    "iso-2022").
-
-    
 macross -- MOBJECT_XXX
-
-    They start by 'M' followed by upper case object names.
-
-    
 types -- MObject or MObjectXxx
-
-    They start by 'M' followed by capitalized object names (e.g.
-    MConverter, MInputDriver).

-    not yet freed on the call of M17N_FINI ().
-
-    
 MDEBUG_CHARSET -- If set to 1, print information about
-    charsets being loaded from the m17n database.
-
-    
 MDEBUG_CODING -- If set to 1, print information about coding
-    systems being loaded from the m17n database.
-
-    
 MDEBUG_DATABASE -- If set to 1, print information about
-    data being loaded from the m17n database.
-
-    
 MDEBUG_FONT -- If set to 1, print information about fonts
-    being selected and opened.
-
-    
 MDEBUG_FONT_FLT -- If set to 1, print information about which
-    command of Font Layout Table are being executed.

-    @brief GUI support for a window system
-
-    This section defines the m17n GUI API concerning M-text drawing
-    and inputting under a window system.
-
-    All the definitions here are independent of window systems.  An
-    actual library file, however, can depend on a specific window
-    system.  For instance, the library file m17n-X.so is an example of
-    implementation of the m17n GUI API for the X Window System.
-
-    Actually the GUI API is mainly for toolkit libraries or to
-    implement XOM, not for direct use from application programs.

-    @brief Create a new frame.
-
-    The mframe () function creates a new frame with parameters listed
-    in $PLIST.
-
-    The recognized keys in $PLIST are window system dependent.
-
-    The following key is always recognized.
-
-    
-
-     #Mface, the value type must be (MFace *).
-
-    The value is used as the default face of the frame.
-
-    
-
-    In addition, in the m17n-X library, the following keys are
-    recognized.  They are to specify the root window and the depth of
-    drawables that can be used with the frame.
-
-    
-
-     #Mdrawable, the value type must be Drawable
-
-    A parameter of key #Mdisplay must also be specified.  The
-    created frame can be used for drawables whose root window and
-    depth are the same as those of the specified drawable on the
-    specified display.
-
-    When this parameter is specified, the parameter of key #Mscreen
-    is ignored.
-
-    
 #Mwidget, the value type must be Widget.
-
-    The created frame can be used for drawables whose root window and
-    depth are the same as those of the specified widget.
-
-    If a parameter of key #Mface is not specified, the default face
-    is created from the resources of the widget.
-
-    When this parameter is specified, the parameters of key #Mdisplay,
-    #Mscreen, #Mdrawable, #Mdepth are ignored.
-
-    
 #Mdepth, the value type must be unsigned.
-
-    The created frame can be used for drawables of the specified
-    depth.
-
-    
 #Mscreen, the value type must be (Screen *).
-
-    The created frame can be used for drawables whose root window is
-    the same as the root window of the specified screen, and depth is
-    the same at the default depth of the screen.
-
-    When this parameter is specified, parameter of key #Mdisplay is
-    ignored.
-
-    
 #Mdisplay, the value type must be (Display *).
-
-    The created frame can be used for drawables whose root window is
-    the same as the root window for the default screen of the display,
-    and depth is the same as the default depth of the screen.
-
-    
 #Mcolormap, the value type must be (Colormap).
-
-    The created frame uses the specified colormap.
-

-    @brief M-text objects and API for them.
-
-    In the m17n library, text is represented as an object called @e
-    M-text rather than as a C-string (char * or unsigned
-    char *).  An M-text is a sequence of characters whose length
-    is equals to or more than 0, and can be coined from various
-    character sources, e.g. C-strings, files, character codes, etc.
-
-    M-texts are more useful than C-strings in the following points.
-
-    @li M-texts can handle mixture of characters of various scripts,
-    including all Unicode characters and more.  This is an
-    indispensable facility when handling multilingual text.
-
-    @li Each character in an M-text can have properties called @e text
-    @e properties. Text properties store various kinds of information
-    attached to parts of an M-text to provide application programs
-    with a unified view of those information.  As rich information can
-    be stored in M-texts in the form of text properties, functions in
-    application programs can be simple.
-
-    In addition, the library provides many functions to manipulate an
-    M-text just the same way as a C-string.  */

-
-    If $FORMAT is MTEXT_FORMAT_US_ASCII and the byte-sequence

-    @brief Symbol objects and API for them.
-
-    The m17n library uses objects called @e symbols as unambiguous
-    identifiers.  Symbols are similar to atoms in the X library, but a
-    symbol can have zero or more @e symbol @e properties.  A symbol
-    property consists of a @e key and a @e value, where key is also a
-    symbol and value is anything that can be cast to (void
-    *).  "The symbol property that belongs to the symbol S and
-    whose key is K" may be shortened to "K property of S".
-
-    Symbols are used mainly in the following three ways.
-
-    @li As keys of symbol properties and other properties.
-
-    @li To represent various objects, e.g. charsets, coding systems,
-    fontsets.
-
-    @li As arguments of the m17n library functions to control
-    their behavior.
-
-    There is a special kind of symbol, a @e managing @e key.  The
-    value of a property whose key is a managing key must be a @e
-    managed @e object.  See @ref m17nObject for the detail.

-    @brief Get the value of the topmost text property.
-
-    The mtext_get_prop () function searches the character at $POS in
-    M-text $MT for the text property whose key is $KEY.
-
-    @return
-    If a text property is found, mtext_get_prop () returns the value
-    of the property.  If the property has multiple values, it returns
-    the topmost one.  If no such property is found, it returns @c NULL
-    without changing the external variable #merror_code.
-
-    If an error is detected, mtext_get_prop () returns @c NULL and
-    assigns an error code to the external variable #merror_code.
-
-    @note If @c NULL is returned without an error, there are two
-    possibilities:
-
-    @li  the character at $POS does not have a property whose key is $KEY, or 
-
-    @li  the character does have such a property and its value is @c NULL.  
-
-    If you need to distinguish these two cases, use the
-    mtext_get_prop_values () function instead.  */

-    @brief Find the range where the value of a text property is the same.
-
-    The mtext_prop_range () function investigates the extent where all
-    characters have the same value for a text property.  It first
-    finds the value of the property specified by $KEY of the character
-    at $POS in M-text $MT.  Then it checks if adjacent characters have
-    the same value for the property $KEY.  The beginning and the end
-    of the found range are stored to the variable pointed to by $FROM
-    and $TO.  The character position stored in $FROM is inclusive but
-    that in $TO is exclusive; this fashion is compatible with the
-    range specification in the mtext_put_prop () function, etc.
-
-    If $DEEPER is not 0, not only the topmost but also all the stacked
-    properties whose key is $KEY are compared.
-
-    If $FROM is @c NULL, the beginning of range is not searched for.  If
-    $TO is @c NULL, the end of range is not searched for.
-
-    @return
-
-    If the operation was successful, mtext_prop_range () returns the
-    number of values the property $KEY has at pos.  Otherwise it
-    returns -1 and assigns an error code to the external variable @c
-    merror_code.  */
