       vol-0 - afnix installation guide


       This  chapter  describes  the  installation  procedures  for the  AFNIX
       writing system distribution. This  chapter  explains  how  to  set  and
       compile this distribution.

       Software distribution
       The  complete  distribution can be downloaded from the AFNIX home page.
       The result is a complete source tree that is ready for compilation. The
       distribution  contains  also the documentation as well as examples. The
       distribution is supported on a variety of platforms as indicated  below
       that  can  be  either  32 bits or 64 bits machines. The distribution is
       also available at the FreeBSD port collection.

       Platform   Processor                                   Operating system
       Linux      X86-32, X86-64, IA64, SPARC-32, SPARC-64    Linux 2.4 and 2.6
       FreeBSD    X86-32, X86-64, IA-64, SPARC-32, SPARC-64   FreeBSD 5.x, 6.x, 7.x
       Darwin     PPC-32, PPC-64, X86-32, X86-64              MacOS X 10.4 Tiger, 10.5 Leopard, 10.6 S

       Specific processors like  the  Alpha,  M68K,  ARM  and  MIPS  are  also
       supported  on  certain  distribution  like  Debian.  The  PowerPC (PPC)
       processor is primarily supported with the Darwin platform  (MACOS)  and
       is also working with the Linux platform. The Solaris SPARC platform has
       been discontinued. Do not hesitate to contact the development team  for
       specific processor or platform support.

       Installation procedure
       The  core  software  is  written in C++. It has been successfully built
       with the GNU GCC 3 and GCC 4. No other compiler have been  tested.  You
       will  also  need  the  GNU  Make  package.  With some distributions the
       command is called gmake. Note that the Makefile hierarchy  is  designed
       to operate safely with the -jGNU Make option.

       Unpacking the distribution
       The  distribution  is available as a compressed tar file. Note that the
       documentation is distributed in a separate file. The following  command
       unpacks the distribution.

       zsh> gzip -d afnix-src-[version].tar.gz
       zsh> tar  xf afnix-src-[version].tar

       Quick command reference
       The  list  of  commands  to  execute  is  given in the example below. A
       detailed description for each command  is  given  hereafter.  The  make
       world  command  is  the default command that builds the whole tree with
       the default compiler.

       zsh> ./cnf/bin/afnix-setup -o --prefix=/usr/local/afnix
       zsh> make status
       zsh> make [-j]
       zsh> make test
       zsh> make install
       zsh> make clean

       With some platforms, the make command should be replaced by  the  gmake
       command.  The make status command is optional and can be used to report
       the internal  value  contents.  In  particular,  the  version  and  the
       installation parameters are reported.

       The   afnix-setup   command  can  be  invoked  to  setup  a  particular
       configuration. You should have  your  compiler  on  your  search  path.
       Normally, the command given below is enough.

       zsh> ./cnf/bin/afnix-setup -o --prefix=/usr/local/afnix

       This  command  checks  that  the  target  platform  can be detected and
       configured. The -o option configures the compilation in optimized mode.
       Use  the  -g option can be used to configure the build process in debug
       mode. The --prefix option sets the installation  directory.  Note  that
       the  compilation  process is done in the distribution tree and that the
       --prefix option affects only the installation operations. The -v option
       is the verbose option. Other options are available for fine tuning.

       Option       Description                           Default
       -h           Print a help message                  n/a
       -v           Set the verbose mode                  n/a
       -g           Set the debug mode                    yes
       -o           Set the optimized mode                no
       --help       Same as -h                            n/a
       --prefix     Set the target install directory      /usr/local
       --shrdir     Set the shared install directory      /usr/local/share
       --altdir     Set the alternate install directory   /usr/local
       --sdkdir     Set the system kit directory          platform dependent
       --compiler   Set the default compiler              platform dependent
       --proctype   Set the processor type                generic
       --dynamic    Compile and link dynamically          yes
       --static     Compile and link statically           no

       The  prefix  option set the root installation directory. The binary and
       library installation directories are derived from it.  The  shrdir  set
       the  shared  installation  directory  which  is  normally  used for the
       installation of the manual pages on most popular  systems.  the  altdir
       sets the alternate installation directory. Normally this path should be
       empty as it affects the path for the etc directory. This flag should be
       used when using a prefix to unusual destination. the sdkdir option sets
       the path of the platform system development kit. This  option  is  only
       used with the Darwin platform. The compiler option can be used to force
       a particular compiler with the help of a compiler  configuration  file.
       The  proctype  option  can  be  used  to  force  a particular processor
       architecture. The -s or --static option can be used to build  a  static
       executable.  Normally, this option should not be used since it restrict
       the use of extension modules. The dynamic controls whether or  not  the
       dynamic   libraries   should   be   built.   This  option  is  detected
       automatically for a particular platform and  should  be  used  only  by
       package maintainer.

       Compiling the distribution
       The  compilation  process  is straightforward. With some platforms, the
       make accepts the -j that enables concurrent operations.

       zsh> make [-j]

       This will build the complete distribution locally. If an error  occurs,
       it  is  best to report it at the ( AFNIX bug report mail

       Testing the distribution
       The distribution contains all test suites. The test suites are compiled
       and executed with the following command.

       zsh> make test

       This  command  run the test suites for each library as well as the test
       suites for each application client.  Most  of  the  base  library  test
       suites  are  written in C++ with the application test suites written in
       the core writing system.

       Installing the distribution
       Once the system has been built and tested,  it  can  be  installed.  By
       default,  the  distribution  tree  is  installed  into  the  /usr/local
       directory. This can be overwritten with the --prefix option during  the
       configuration process.

       zsh> make install

       There  are  several variables that controls the behavior of the install
       rule. Each variable  has  its  default  value  sets  during  the  setup
       configuration.  However,  this  variable can also be altered during the
       installation process

       Variable   Description                          Default
       PREFIX     The root install directory           /usr/local
       SHRDIR     The shared install directory         /usr/local/share
       ALTDIR     The shared alternate directory       /usr/local/etc
       SDKDIR     The system  kit directory            platform dependent
       BINDIR     The binary install directory         prefix/bin
       LIBDIR     The library install directory        prefix/lib
       HDRDIR     The header files install directory   prefix/include/afnix
       ETCDIR     The extra files install directory    altdir/etc/afnix

       Installing the documentation
       The documentation is installed independently of the software.  The  doc
       rule  builds  the  documentation  and  the  publish  rule  installs the
       documentation.  Several  variables  also  control   the   documentation
       installation path.

       Variable   Description                           Default
       DOCDIR     The documentation install directory   shrdir/doc/afnix
       MANDIR     The manual pages install directory    shrdir/man

       Cleaning the distribution
       The distribution is cleaned with the clean rule.

       zsh> make clean

       This rule does not clean the configuration. For a complete cleaning the
       reset rule is more appropriate.

       zsh> make reset

       Running AFNIX
       The axi command invokes the interpreter. In order to operate  properly,
       the  LD_LIBRARY_PATH  environment  variable must be configured with the
       directory containing the shared libraries. If the libraries  have  been
       installed  in a standard location like /usr/local/lib, there is nothing
       to do.

       Running some example
       The directory exp contains various examples  which  can  be  run.  Each
       example  is  labeled  according  to  their  use  in the volume 1 of the
       documentation set. Example 0101.als prints  the  message  hello  world.
       Example   0501.als   prints   various   information  about  the  system

       zsh> axi 0501
       major version number   : 2
       minor version number   : 1
       patch version number   : 1
       interpreter version    : 2.1.1
       operating system name  : linux
       operating system type  : unix
       afnix official uri     :

       Special features
       The build process provides several features that permits  to  customize
       the  compilation process as well as the nature of the final executable.
       Most of the time, these options are reserved for the package maintainer
       and are given below for illustration purpose.

       Target customization
       The  distribution  can  be  configured to operate on a specific machine
       target. For example, a typical Linux box  will  be  compiled  with  the
       default  compiler target, which is the 386 processor. You can force the
       compilation to be optimized for a particular processor.  This  is  done
       with  the  --proctype  option of the afnix-setup command. Currently the
       distribution supports the 586  and  686  architectures  for  the  Intel
       platform. The ultra architecture is valid for the SPARC platform.

       zsh> cnf/bin/afnix-setup -o --prefix=/usr/local

       This   command   will   configure   the  distribution  to  be  compiled
       specifically for the Pentium architecture.

       Special target extensions
       Extensions are specific libraries or executables which  are  not  build
       automatically  during  the  build  process.  The user is responsible to
       decide which extension is needed for  the  system  All  extensions  are
       located  under the src/ext directory. Simply going into the appropriate
       directory and running the make command will build the  extension.   The
       asi   extension   creates  a  static  interpreter  with  all  libraries
       automatically included in the final executable. The extension is simply
       build  with  the  following command. Note that this extension overwrite
       the previous executable in the bld/bin directory.

       zsh> make -C src/ext/asi

       Extra files
       The distribution comes with some extra files. The most important is the
       Emacs  mode  afnix-mode.  The  original source file is written in Emacs
       Lisp and is available in the etc directory of  the  distribution.  This
       file should be installed according to the current Emacs installation.


       This chapter contains additional notes for the package maintainer. They
       are also useful for  anybody  who  is  in  charge  of  integrating  the
       distribution in a build process. The chapter describes the distribution
       tree with more details.

       The distribution tree
       The distribution tree is composed of various directories. Each of  them
       has a Makefile which can be called locally or from the top level.

              This  directory  contains  the  configuration  distribution  and
              various utilities. Normally you should not touch it, unless  you
              are using a compiler different than gcc.

              This  directory  contains  the  complete source tree. The source
              code  is  written  in  C++.  Normally  this  directory  is  left
              untouched.  If  there  are  good  reasons  to  modify it, please
              contact the development team.

              This directory contains  the  complete  test  suites.  The  test
              suites   are   used  by  various  programs  including  the  main
              interpreter, the compiler and the debugger. It  shall  be  noted
              that  the  library  distribution  also  includes  specific  test

              This directory contains the complete documentation written in in
              XML with a special DTD. It should be left untouched.

              This  directory  contains  various  files  associated  with  the
              distribution. Some files are useful to be copied.

              This directory contains various examples. They are included  for
              illustration purpose.

       The  process  of  building a package solely depends on the distribution
       type. Most likely, the standard distribution should contain the  binary
       executables  as  well  as some configuration file and the manual pages.
       The documentation and the development header files can put in  separate

       Configuration and setup
       The  configuration  process involves the use of the afnix-setup command
       located in the cnf/bin directory. This command is used to configure the
       distribution.  Package  maintainers  are  encouraged  to  use  it  with
       specific options.

       Platform detection
       The afnix-guess command is used during  the  configuration  process  to
       detect  a  supported  platform.  This command can be run in stand-alone
       mode. Various options can be used  to  tune  the  type  of  information

       Option   Description
       -h       Print a help message
       -n       Print the platform name
       -v       Print the platform version
       -M       Print the platform major number
       -m       Print the platform minor number
       -p       Print the platform patch number
       -t       Print the processor type

       Without option, the utility prints a platform and processor description

       zsh> ./cnf/bin/afnix-guess

       Platform defaults
       The directory cnf/def contains a platform specific  default  file.  The
       file  determines  what  is  the default compiler and linking mode. This
       file is used by  the  afnix-setup  command.  For  example,  the  afnix-
       darwin.def file contains:

       compiler: gcc
       lktype  : dynamic
       lkmode  : dylib

       Such  options  instructs  the  configuration  utility, that the default
       compiler is gcc and the linking mode should operates in dynamic mode by
       using  the dylib rule. These default values can be overwritten with the
       equivalent option of the afnix-setup command. Note  that  the  compiler
       version  is  automatically  detected  by  the  system.  The afnix-vcomp
       command will return the appropriate compiler  version  running  on  the
       target system.

       C++ source file conventions
       THe  source  tree  has  two  types of C++ files. The first type has the
       extension .cxx and the second type has the extension .cpp. The .cxx  --
       and  the  associated  .hxx  -- files are only used to indicate a system
       dependency. These files are found only in  the  src/lib/plt  directory.
       The  .cxx  extension  indicates that the file might use system specific
       include files. The .cpp -- and the associated .hpp  --  files  are  the
       normal  C++  source  files. The .cpp extension is used to indicate that
       these files will not use a system specific file. By default  this  rule
       is  enforced  in  the  compiler  configuration  file by specifying some
       compiler flags which do not authorize such access.

       Configuration files
       The configurations files are located in the cnf/mak directory. Normally
       they  should  be  left  untouched. The most important one is the afnix-
       rule.mak file that defines most of the compilation and  linking  rules.
       Additionally,  during  the  setup  operation,  the  afnix-setup command
       creates several files in the bld/cnf directory. The bld  is  the  build
       directory.  The  afnix-plat.mak file is the platform configuration file
       and  the  afnix-comp.mak  is  a  link  to  the   appropriate   compiler
       configuration file.

       Normally,  the compilation process is immediate. Just invoking the make
       command will do the job. However,  some  package  maintainer  have  the
       desire to overwrite some flags. Some options are provided to facilitate
       this task.

              This flag can be used to add some compilation flags for all .cpp

              This flag can be used to add some compilation flags for all .cxx

              This flag can be used to add some  compilation  definitions  for
              all source files.

              This flag can be used to add some compilation paths for the .cxx

       For example, it is common to have some maintainer to compile with  both
       the  debug  and  optimize  flags.  This  can be done with the following
       command (assuming an optimized configuration):


       All include files, compiled libraries and executables are placed in the
       bld  directory.  This  directory  contains  the  bld/bin  for binaries,
       bld/lib for libraries and bld/hdr for the header files.

       Building the package
       The package can be built by accessing the bld directory or by  invoking
       the  install  rule.  The  second  method is not recommended for package
       construction, since it might trigger some file installation without any
       control.   The  etc directory contains some special files that might be
       used for the package construction. A  sample  list  of  them  is  given

              This file is the Emacs mode.

              This file is the debugger Emacs gud mode.

       Specific makefile rules
       The  top level Makefile contains several rules that might be useful for
       the package maintainer.

              This rule show the configuration status for each parameters with
              the version.

              This rule invokes the default configuration in debug mode.

              This rule invokes the default configuration in optimized mode.

              This  rule  invokes  the default configuration in debug mode and
              compile the whole distribution. The default install directory is

              This  rule  invokes  the default configuration in optimized mode
              and  compile  the  whole  distribution.  The   default   install
              directory is /usr/local.

              This rule runs all test suites.

              This rule builds the documentation.

              This rule builds the distribution.

              This rule installs the distribution.

              This rule installs the documentation.

              This rule cleans the distribution but keep the configuration.

              This rule resets the distribution including the configuration.


       This  chapter  contains  the release notes for the differents releases.
       Release notes are given in descending order for a  particular  version.
       The   standard   notation   is   major.minor.patch   which   represents
       respectively, the major, minor and patch number. A major version number
       changes  indicates  a substantial change in the distribution, including
       new tools, application interface and license. A  minor  version  number
       change  indicates  noticeable  change,  with  or  without new tools but
       without application interface change nor  license  change.  Finally,  a
       patch  number change indicates a simple change to fix problem. There is
       no additional features in a patch nor an application interface change.

       Release features

              Core engine: standard objects
              The BlockBuffer object has been added  to  the  standard  object
              library.  Furthermore, the Buffer has been adapted to operate as
              a base class for the block buffer and the shl  method  has  been
              added  to  the  buffer  object as a mean to shift the buffer. As
              consequence, the default operating mode for a buffer is the BYTE
              mode.  When  operating with strings, the UTF8 mode might be more
              suitable. The BitSet object has been renamed to Bitset  and  the
              interface  has  been  cleaned.  The Vector has been cleaned. The
              object-p predicate has been fixed.

              support  the Unicode 5.0 standard. With this release, the string
              normalization scheme  is  now  in  place  and  used  by  default
              internally.  This  implies  among other things, a better support
              for multiple diacritics as well as the beginning of the standard
              collation algorithm.

              Core engine: log file support
              The   Logger  base  class  has  been  enhanced  to  support  the
              generation of a log file. An output stream can now be  bound  to
              the object.

              Core engine: class defer support
              The  concept  of  class defer object has been added to the Class
              object. The defer mode is the opposite of  the  infer  mode  and
              provides a mechanism for base class creation.

              Core engine: print table header
              The  PrintTable  object has been enhanced to support the concept
              of table header.

              keyword   throw.  This  provides  a  mechanism  to  re-throw  an

              Core engine: critical bug with return form
              A critical bug in the core engine affecting the behavior of  the
              return  reserved keyword in a try block has been fixed. A return
              form inside a try block was incorrectly generating an  exception
              which was subsequently caught by the try block.

              Core modules: net module
              The base network module has been enhanced to better operate with
              IPV6. In particular, when both IPV4 and IPV6 stacks are  present
              and a host name (typically localhost) have an address entry, the
              socket constructor make sure it can build an  object.  The  IPV6
              address display has been rewritten.

              Core modules: sio module
              A  new  object  called  Pathname  has  been added to support the
              manipulation of system path.  In  addition,  two  new  functions
              mkdir  and  mhdir  have been also added to support the directory
              creation, both normally and hierarchically.

              Core modules: nwg module
              The Uri has been dramatically enhanced to  conform  to  the  RFC
              3986.  In  particular,  the  path  representation for urn is now
              working properly. The cookie object has been massaged to support
              the  cookie version 1, although it does not seem to be supported
              (yet!) by the browsers.

              Core modules: xml module
              The xml module has been  enhanced  with  a  new  parsing  system
              called  the  simple model. In the simple model, nodes are parsed
              in a linear fashion. The node content is available in  the  form
              of a string and its interpretation is at the user discretion.

              Core service: wax service
              The afnix-wam service has been renamed as afnix-wax. The service
              has also been updated with two new objects, namely  the  XmlMime
              and XhtmlMime which permits to build a mime representation of an
              xml tree. Several xhtml objects have also been added to complete
              the collection. This include the XhtmlScript for example.

              Core service: xpe service
              The  afnix-xpe  service has been added as a new service. The xml
              processing environment  (xpe)  provides  a  xml  processor  that
              permits  manipulate  the whole xml tree with the help of various
              xml processor features. In particular, the service provides  the
              support for the xml include extension.

              Core projects: apx project
              This  release  incorporates  for  the first time, the concept of
              core project, which represents a librarian  or  an  application.
              The  first  project is the AFNIX protocol extension or apx which
              is a message based protocol designed to transport  request/reply
              messages  within  a  client/server  environment.  The message is
              built with the  xml  library  and  the  librarian  provides  the
              encapsulation layer.

              Core projects: amd project
              The  AFNIX media dumper or amd project is a complete application
              designed  to  illustrate  the  design  of  an  application.  The
              application permits to dump an uri content into a file.

              The core engine has been substantially changed  to  support  the
              new  Unicode  5.0  standard.  As  of now, the engine is in place
              internally, but not fully activated. In particular,  the  string
              normalization is implemented but not activated. The next release
              should incorporate the full system with a change that should  be
              transparent to the user.

              Core language: instance inference
              An  instance  inference  mechanism -- which is equivalent to the
              concept of virtual constructor -- has been  added  to  the  core
              engine.  Such  system permits to derive top instance from a base
              instance construction.

              Core language: print table object
              The PrintTable object has  been  enhanced  with  a  dump  method
              similar to the format method.

              Core language: property list object
              The  Property  and  the  Plist  objects  have  been added to the
              standard library. a property is name/value  pair.  The  property
              list object is an iterable object that stores property objects.

              Core modules: xml module
              A  new  module  called  afnix-xml  has  been  added.  The module
              provides the foundation for a  full  xml  1.0/1.1  support.  The
              module  also includes a parser that permits to build xml tree. A
              xml tree writer is also part of the module functionality. A  xml
              processor  is  not  yet  available  and  is expected in the next

              Core modules: nwg module
              A new  module  called  afnix-nwg  has  been  added.  The  module
              provides  the support for the network working group objects such
              like Uri object. The module also provides the foundation for the
              mime support.

              Core modules: web module
              The afnix-web module has been removed and replaced by the afnix-
              wam service.

              Core service: wam service
              The afnix-wam service has been added as the first  service  into
              the  core  distribution.  A service differs from a module in the
              sense that it is a combination of  different  modules.  The  web
              application  management  service  depends  on  the  xml  and nwg
              modules. The service provides all the functionality to support a
              http  session,  including  xhtml page generation and cgi request

       Release 1.3

       Release features

              Core language: ISO-8859 transcoding support
              The core engine has  been  modified  to  integrate  a  character
              transcoder  that permits the support all ISO-8859 codesets which
              are  mostly  used  for  the  encoding  of  european  and  arabic
              characters.  Depending  on  the  locale settings, the transcoder
              automatically remaps the 8 bits characters into their respective
              unicode character. All clients have been updated to detect their
              associated locale  and  to  set  automatically  the  appropriate
              transcoder. A new option -e has been added to force a particular

              Core language: Logger base class
              A logging base  class  has  been  added.  The  logging  facility
              provides the interface to store messages by time and level. This
              class is further extended in the modules.

              Core language: Heap class
              A heap class has been added. The heap can operate  in  ascending
              or  descending  mode. This class can be used to support priority

              Core language: Option class
              An option class has been added  in  order  to  ease  the  option
              capture  when  designing  an  application.  The class permits to
              define  the  valid  options  and  offer  a  powerful   retrieval

              Core language: Date class
              The  Time class has been completely changed and a new Date class
              has been added. The new mechanism provides a  better  separation
              between  the  time  and  the  date,  increase the date range and
              authorizes the support for multiple calendar.

              Client: cross spreadsheet client
              The axs client has been  modified  to  support  the  axs:insert-
              marker, axs:insert-header and insert-footer control commands.

              Core modules: speadsheet module
              The  Folio  and Sheet classes have been substantially updated to
              support additional information.  The  Sheet  also  supports  the
              concept of markers that marks the sheet columns by literals. The
              concept of column tagging has been  added  with  the  associated
              search  methods.  All classes also contain an information field.
              The importation mechanism now supports a cons cell that  defines
              both the cell name and the cell value.

              Core modules: web module
              The  Table  class  has  been  modified to support the concept of
              table data header. The associated methods have been added to the
              class  and  a  new  HtmlTh  has  been  added. The concept of tag
              propagation has also  been  added.  If  a  tag  element  already
              exists, this one is not added. This is particularly true for the
              class tag that  is  now  part  of  the  class  constructor.  The
              HtmlPage class has been put in strict conformance with xhtml 1.1
              and the XHtmlpage class has been removed.

              Core modules: pim module
              A new module called the afnix-pim module has been added  to  the
              base  distribution.  The  personal information management or pim
              module  is  designed  to  ease  the   management   of   personal
              information and agenda.

              Core modules: gfx module
              A  new  module called the afnix-gfx module has been added to the
              base distribution. The  module  contains  the  base  class  that
              supports  the  graph data structure which was previously part of
              the standard library.

       Release 1.2

       Release features

              Core language: Unicode support
              The core engine has been substantially modified to integrate the
              support for Unicode characters. Depending on the system settings
              the reader automatically adjust itself to operate in  byte  mode
              or  in  UTF-8  mode.  The  String  and Character classes are now
              operating with  a  Unicode  representation.  The  design  of  an
              Unicode  based  engine  also  impacts  several  classes like the
              Regex, Buffer and stream classes. A new  class  called  Byte  is
              also  designed to handle byte character. A new stream model with
              a base Stream class has also been added. The full  support  with
              Unicode  character  is not yet completed. In particular, certain
              codesets are not supported at all.  This  is  particularly  true
              with case-conversion functions.

              Core language: orphan instance and reparenting
              The  object  model  now supports the creation of orphan instance
              which is an  instance  without  a  class  attached  to  it.  The
              instance  can  be later bound to a class and such class can even
              be changed during the course of the program execution.

              Core modules: network module
              The Address class has been updated  to  reflect  the  access  to
              address aliases.

              Core modules: text processing module
              The  Literate  class  has been updated to reflect the support of
              Unicode characters. The class can operate both in byte  mode  or
              in Unicode character mode.

       Release 1.1

       Release features

              Core language: Large file support
              Support  for  the  large  file system has been added in the base
              distribution. All input/output operations as long  as  they  are
              supported by the operating system are now done in 64 bits mode.

              Core libraries: Secure hash algorithm
              The  cryptographic  library  incorporates  the  support  for the
              SHA-1, SHA-256, SHA-384 and SHA-512 hash algorithms.

              Core libraries: Standard symmetric cipher
              The cryptographic  library  incorporates  the  support  for  the
              Advanced Encryption Standard (AES) as a symmetric cipher.

              Core libraries: ODC library renamed
              The  ODC  library  has  been  renamed  to  SPS  which stands for
              spreadsheet  library.  This  new   name   is   considered   more
              appropriate for the function the library achieves.

              Core libraries: xhtml 1.1 support
              The  XhtmlPara class is now configured to support XHTML 1.1 with
              utf-8 encoding.

              Documentation: XML based documentation
              The documentation has been rewritten completely in XML. A DTD as
              well  as the necessary XSLT style sheets have also been designed
              to produce a professional documentation which can  be  used  for
              printing or for online browsing.
