The Free Translation Project +is a way to get maintainers of free software, translators, and users all +together, so that will gradually become able to speak many languages. +A few packages already provide translations for their messages. + + If you found this `ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU `gettext' internally, +itself available at your nearest GNU archive site. But you do *not* +need to install GNU `gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work at translations should contact the appropriate team. + + When reporting bugs in the `intl/' directory or bugs which may be +related to internationalization, you should tell about the version of +`gettext' which is used. The information can be found in the +`intl/VERSION' file, in internationalized packages. + +One advise in advance +===================== + + If you want to exploit the full power of internationalization, you +should configure it using + + ./configure --with-included-gettext + +to force usage of internationalizing routines provided within this +package, despite the existence of internationalizing capabilities in the +operating system where this package is being installed. So far, only +the `gettext' implementation in the GNU C library version 2 provides as +many features (such as locale alias or message inheritance) as the +implementation here. It is also not possible to offer this additional +functionality on top of a `catgets' implementation. Future versions of +GNU `gettext' will very likely convey even more functionality. So it +might be a good idea to change to GNU `gettext' as soon as possible. + + So you need not provide this option if you are using GNU libc 2 or +you have installed a recent copy of the GNU gettext package with the +included `libintl'. + +INSTALL Matters +=============== + + Some packages are "localizable" when properly installed; the +programs they contain can be made to speak your own native language. +Most such packages use GNU `gettext'. Other packages have their own +ways to internationalization, predating GNU `gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system provides +usable `catgets' (if using this is selected by the installer) or +`gettext' functions. If neither is available, the GNU `gettext' own +library will be used. This library is wholly contained within this +package, usually in the `intl/' subdirectory, so prior installation of +the GNU `gettext' package is *not* required. Installers may use +special options at configuration time for changing the default +behaviour. The commands: + + ./configure --with-included-gettext + ./configure --with-catgets + ./configure --disable-nls + +will respectively bypass any pre-existing `catgets' or `gettext' to use +the internationalizing routines provided within this package, enable +the use of the `catgets' functions (if found on the locale system), or +else, *totally* disable translation of messages. + + When you already have GNU `gettext' installed on your system and run +configure without an option for your new package, `configure' will +probably detect the previously built and installed `libintl.a' file and +will decide to use this. This might be not what is desirable. You +should use the more recent version of the GNU `gettext' library. I.e. +if the file `intl/VERSION' shows that the library which comes with this +package is more recent, you should use + + ./configure --with-included-gettext + +to prevent auto-detection. + + By default the configuration process will not test for the `catgets' +function and therefore they will not be used. The reasons are already +given above: the emulation on top of `catgets' cannot provide all the +extensions provided by the GNU `gettext' library. If you nevertheless +want to use the `catgets' functions use + + ./configure --with-catgets + +to enable the test for `catgets' (this causes no harm if `catgets' is +not available on your system). If you really select this option we +would like to hear about the reasons because we cannot think of any +good one ourself. + + Internationalized packages have usually many `po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at `configure' time by using the +`--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable `LINGUAS' +may be set, prior to configuration, to limit the installed set. +`LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +Using This Package +================== + + As a user, if your language has been installed for this package, you +only have to set the `LANG' environment variable to the appropriate +ISO 639 `LL' two-letter code prior to using the programs in the +package. For example, let's suppose that you speak German. At the +shell prompt, merely execute `setenv LANG de' (in `csh'), +`export LANG; LANG=de' (in `sh') or `export LANG=de' (in `bash'). This +can be done from your `.login' or `.profile' file, once and for all. + + An operating system might already offer message localization for +many of its programs, while other programs have been installed locally +with the full capabilities of GNU `gettext'. Just using `gettext' +extended syntax for `LANG' would break proper localization of already +available operating system programs. In this case, users should set +both `LANGUAGE' and `LANG' variables in their environment, as programs +using GNU `gettext' give preference to `LANGUAGE'. For example, some +Swedish users would rather read translations in German than English for +when Swedish is not available. This is easily accomplished by setting +`LANGUAGE' to `sv:de' while leaving `LANG' to `sv'. + +Translating Teams +================= + + For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list, courtesy of Linux +International. You may reach your translation team at the address +`LL@li.org', replacing LL by the two-letter ISO 639 code for your +language. Language codes are *not* the same as the country codes given +in ISO 3166. The following translation teams exist, as of December +1997: + + Chinese `zh', Czech `cs', Danish `da', Dutch `nl', English `en', + Esperanto `eo', Finnish `fi', French `fr', German `de', Hungarian + `hu', Irish `ga', Italian `it', Indonesian `id', Japanese `ja', + Korean `ko', Latin `la', Norwegian `no', Persian `fa', Polish + `pl', Portuguese `pt', Russian `ru', Slovenian `sl', Spanish `es', + Swedish `sv', and Turkish `tr'. + +For example, you may reach the Chinese translation team by writing to +`zh@li.org'. + + If you'd like to volunteer to *work* at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is *not* the same as the list itself, it has +`-request' appended. For example, speakers of Swedish can send a +message to `sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate +*actively* in translations, or at solving translational difficulties, +rather than merely lurking around. If your team does not exist yet and +you want to start one, or if you are unsure about what to do or how to +get started, please write to `translation@iro.umontreal.ca' to reach the +coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skill are praised more than +programming skill, here. + +Available Packages +================== + + Languages are not equally supported in all packages.

+
+Introduction
+------------
+
+The coding standard we use are based on the GNU coding standards
+available at http://www.gnu.org/prep/standards_toc.html
+and on the Gnome Coding standards available at
+http://developer.gnome.org/doc/guides/programming-guidelines/book1.html .
+
+Please, make sure you read these documents before you read this one.
+
+I) General coding style rules
+---------------------------
+
+Coding style refers to the way the code is formatted.
+Here are the guidelines we use in this project:
+
+Indentation Style
+- - - - - - - - - -
+
+We use the 2-spaces tab indentation style (the GNU's one) .
+
+Make sure as much as possible that each code line does not
+exceed 80 characters length. Why ? because you don't know
+who will read your code. The smallest screens are 80 chars
+wide. So, please, make the code available to everybody.
+
+
+Functions naming
+- - - - - - - -
+
+We use the GNU name scheme to name our functions.
+
+GOOD:
+
+int
+my_function_name (char a_variable_name)
+{
+ printf ("The variable value is %c", a_variable_name) ;
+ return 0 ;
+}
+
+
+BAD:
+
+int
+myFunctionName (char blabla)
+{
+ printf ("This is awfull\n") ;
+}
+
+or
+
+int my_FunctionName (char Blabla) {
+ printf ("This is bad\n") ;
+}
+
+The words of the function names are separared by an underscore ('_') and
+are written in lower case.
+The name functions arguments always start with by a "a_" .
+
+Avoid for instance the Java function (method) name scheme by mixing
+upper and lower case in the function names.
+
+
+Be genereous with white spaces:
+
+GOOD:
+
+int foo (int a_parameter)
+{
+ if (test == TRUE) {
+ printf ("Coucou\n") ;
+ }
+}
+
+BAD:
+
+int foo(int a_parameter)
+{
+ if(test==TRUE) {
+ printf("coucou\n")
+ }
+}
+
+
+To ensure that the each line of code is less than 80 characters,
+if a function has many parameters, you can write it this way:
+
+
+Constants naming
+- - - - - - - - -
+Constants (defines or constant variables) must be in upper case.
+The worlds of the constant name must be separated by an underscore ('_').
+For instance:
+
+GOOD:
+gint A_CONSTANT = 10 ;
+#define ANOTHER_CONSTANT 100 ;
+
+BAD:
+gin a_Constant = 10 ;
+#define another_Constant ;
+
+
+structure and enum naming

+II) Object Oriented C programming

It is + numbered 2 because it goes with version 2 of the ordinary GPL.] + + 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 Library General Public License, applies to some +specially designated Free Software Foundation software, and to any +other libraries whose authors decide to use it. You can use it for +your libraries, too. + + When we speak of free software, we are referring to freedom, 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 or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the 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 a program 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. + + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. + + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, so that any problems introduced by others will not reflect on +the original authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. + + Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License, which was designed for utility programs. This +license, the GNU Library General Public License, applies to certain +designated libraries. This license is quite different from the ordinary +one; be sure to read it in full, and don't assume that anything in it is +the same as in the ordinary license. + + The reason we have a separate public license for some libraries is that +they blur the distinction we usually make between modifying or adding to a +program and simply using it. Linking a program with a library, without +changing the library, is in some sense simply using the library, and is +analogous to running a utility program or application program. However, in +a textual and legal sense, the linked executable is a combined work, a +derivative of the original library, and the ordinary General Public License +treats it as such. + + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. + + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended to +permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to achieve +this as regards changes in header files, but we have achieved it as regards +changes in the actual functions of the Library.) The hope is that this +will lead to faster development of free libraries. + + 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, while the latter only +works together with the library. + + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. + + GNU LIBRARY GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library which +contains a notice placed by the copyright holder or other authorized +party saying it may be distributed under the terms of this Library +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 compile 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) 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. + + c) 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. + + d) 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 source code 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 to +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 Library 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.

It is + numbered 2 because it goes with version 2 of the ordinary GPL.] + + 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 Library General Public License, applies to some +specially designated Free Software Foundation software, and to any +other libraries whose authors decide to use it. You can use it for +your libraries, too. + + When we speak of free software, we are referring to freedom, 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 or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the 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 a program 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. + + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. + + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, so that any problems introduced by others will not reflect on +the original authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. + + Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License, which was designed for utility programs. This +license, the GNU Library General Public License, applies to certain +designated libraries. This license is quite different from the ordinary +one; be sure to read it in full, and don't assume that anything in it is +the same as in the ordinary license. + + The reason we have a separate public license for some libraries is that +they blur the distinction we usually make between modifying or adding to a +program and simply using it. Linking a program with a library, without +changing the library, is in some sense simply using the library, and is +analogous to running a utility program or application program. However, in +a textual and legal sense, the linked executable is a combined work, a +derivative of the original library, and the ordinary General Public License +treats it as such. + + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. + + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended to +permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to achieve +this as regards changes in header files, but we have achieved it as regards +changes in the actual functions of the Library.) The hope is that this +will lead to faster development of free libraries. + + 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, while the latter only +works together with the library. + + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. + + GNU LIBRARY GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library which +contains a notice placed by the copyright holder or other authorized +party saying it may be distributed under the terms of this Library +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 compile 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) 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. + + c) 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. + + d) 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 source code 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.

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 to +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.

Therefore, we avoid to overuse +the C preprocessor magic and all the tricks that tend to turn C into +a maintenance nightmare. + +We also try to adhere to the Gnome coding guidelines specified +at http://developer.gnome.org/doc/guides/programming-guidelines. + + +Reliability +----------- +Each single function of the libcroco library should never crash, +and this, whatever the arguments it takes. +As a consequence we tend to be paranoid when it comes to check +pointers values before dereferencing them for example... + +Conformance +----------- +We try to stick to the CSS spec. We know this is almost impossible to achieve +given the resources we have but we think it is a sane target to chase. + +II) Overall architecture +========================= +The parser is organized around several main classes: + +1/ CRInput +2/ CRTknzr (Tokenizer or lexer) +3/ CRParser +4/ CROMParser + +II.1 The CRInput class +----------------------- +The CRInput class provides the abstraction of +an utf8-encoded character stream. + +Ideally, it should abstract local data sources +(local files and in-memory buffers) +and remote data sources (sockets, url-identified resources) but for the +moment, it can only abstract local data sources. + +Adding a new type of data source should be transparent for the +classes that already use CRInput. After all, this is what abstraction is about :) + + +II.2 The CRTknzr class +---------------------- +The main job of the tokenizer (or lexer) is to +provide a get_next_token() method. +This methods returns the next CSS token found in the input stream. +(Note that the input stream here is an instance of CRInput). + +This provides an extremely useful facility to the parser. + +II.3 The CRParser class +------------------------- +The core of the parser. + +The main job of this class is to provide a cr_parser_parse_stylesheet() +method. During the parsing (the execution of the cr_parser_stylesheet()) +the parser sends events to notify the application when it encounters +remarkable CSS constructions. This is the SAC (Simple API for CSS) API model. + +To achieve that task, almost each production of the CSS grammar +has a matching parsing function (or method) in this class. + +For example, the following production named "ruleset" (specified in the +CSS2 spec in appendix D.1): + +ruleset : selector [ ',' S* selector ]* + '{' S* declaration [ ';' S* declaration ]* '}' S* + +is "implemented" by the cr_parser_parse_ruleset() method. + +The same thing applies for the "selector" production: + +selector : simple_selector [ combinator simple_selector ]* + +which is implemented by the cr_parser_parse_selector() method... and so on +and so forth. + +II.3.1 Structure of a parsing method. +------------------------------------- +A parsing method (e.g cr_parser_parse_ruleset()) is there +to: + + * try to recognize a substring of the incoming character string + as something that matches a given CSS grammar production. + + e.g: the job of the cr_parser_parse_ruleset() is to try + to recognize if "what" comes next in the input stream + is a CSS2 "ruleset". + + * build a basic abstract data structure to + store the information encountered + during the parsing of the current character string. + + eg: cr_parser_parse_declaration() has the following prototype: + + enum CRStatus + cr_parser_parse_declaration (CRParser *a_this, GString **a_property, + CRTerm **a_value) ; + + In case of successful parsing, this method returns + (via its parameters) the property _and_ the + value of the CSS2 declaration. + Note that a CSS2 declaration is specified as follows: + + declaration : property ':' S* expr prio? + | /* empty */ + + * After completion, say if the parsing has succeeded or not. + + eg: cr_parser_parse_declaration() returns CR_OK if the + parsing has succeeded, and error code otherwise. Obviously, + the out parameters "a_property" and "a_value" are valid if and only + if the return value is CR_OK. + + * whenever the function is parsing a construct that must + be notified to the user as part of the SAC API spec, notify + the user by calling the right SAC callback. + + * if the parsing failed, leave the position in the stream unchanged. + That is, the position in the character stream should be as if + the parsing function hasn't been called at all. + + +II.4 The selection Engine. +-------------------------- + +Hmmh, I should kick my ass to write this down ...
