/*! \page commands Special Commands

\section cmd_intro Introduction

All commands in the documentation start with a backslash (<b>\\</b>) or an
at-sign (<b>\@</b>). If you prefer you can replace all commands starting with a 
backslash below by their counterparts that start with an at-sign.

Some commands have one or more arguments. 
Each argument has a certain range:
<ul>
<li>If \<sharp\> braces are used the argument is a single word.
<li>If (round) braces are used the argument extends until the end of the line
    on which the command was found.
<li>If {curly} braces are used the argument extends until the next paragraph.
    Paragraphs are delimited by a blank line or by a section indicator.
</ul>
If [square] brackets are used the argument is optional.

Here is an alphabetically sorted list of all commands with references to their 
documentation:

The following subsections provide a list of all commands that are recognized by
doxygen. Unrecognized commands are treated as normal text.

    Structural indicators
    \htmlonly --- </center>\endhtmlonly</h2>

\section cmdaddtogroup \\addtogroup <name> [(title)]
  \addindex \\addtogroup
  Defines a group just like \ref cmddefgroup "\\defgroup", but in contrast to
  that command using the same \<name\> more than once will not result in a warning,
  but rather one group with a merged documentation and the first title found in
  any of the commands.

  The title is optional, so this command can also be used to add a number of 
  entities to an existing group using \@{ and \@} like this:

\verbatim
  /*! \addtogroup mygrp
   *  Additional documentation for group `mygrp'
   *  @{
   */

  /*!
   *  A function 
   */
  void func1()
  {
  }

  /*! Another function */
  void func2()
  {
  }

  /*! @} */
\endverbatim

  \sa page \ref grouping "Grouping", sections \ref cmddefgroup "\\defgroup", \ref cmdingroup "\\ingroup" and
  \ref cmdweakgroup "\\weakgroup".

\section cmdcallgraph \\callgraph 

  \addindex \\callgraph
  When this command is put in a comment block of a function or method
  and \ref cfg_have_dot "HAVE_DOT" is set to YES, then doxygen will 
  generate a call graph for that function (provided the implementation of the
  function or method calls other documented functions). The call graph will 
  generated regardless of the value of \ref cfg_call_graph "CALL_GRAPH".
  \note The completeness (and correctness) of the call graph depends on the 
  doxygen code parser which is not perfect.

<hr>
\section cmdcallergraph \\callergraph 

  \addindex \\callergraph
  When this command is put in a comment block of a function or method
  and \ref cfg_have_dot "HAVE_DOT" is set to YES, then doxygen will 
  generate a caller graph for that function (provided the implementation of the
  function or method calls other documented functions). The caller graph will 
  generated regardless of the value of \ref cfg_caller_graph "CALLER_GRAPH".
  \note The completeness (and correctness) of the caller graph depends on the 
  doxygen code parser which is not perfect.

<hr>
\section cmdcategory \\category <name> [<header-file>] [<header-name>]

  \addindex \\category
  For Objective-C only: Indicates that a comment block contains documentation 
  for a class category with name \<name\>. The arguments are 
  equal to the \\class command.

  \sa section \ref cmdclass "\\class".

<hr>
\section cmdclass \\class <name> [<header-file>] [<header-name>]

  \addindex \\class
  Indicates that a comment block contains documentation for a
  class with name \<name\>. Optionally a header file and a header name 
  can be specified. If the header-file is specified, a link to a verbatim copy 
  of the header will be included in the HTML documentation. 
  The \<header-name\> argument can be used to overwrite the 
  name of the link that is used in the class documentation to something other 
  than \<header-file\>. This can be useful if the include name is not located 
  on the default include path (like \<X11/X.h\>). With the \<header-name\>
  argument you can also specify how the include statement should look like, 
  by adding either quotes or sharp brackets around the name. 
  Sharp brackets are used if just the name is given.
  
  \par Example: 
  \verbinclude class.h  
  \htmlonly
  Click <a href="$(DOXYGEN_DOCDIR)/examples/class/html/index.html">here</a> 
  for the corresponding HTML documentation that is generated by doxygen.
  \endhtmlonly

<hr>
\section cmddef \\def <name>

  \addindex \\def
  Indicates that a comment block contains documentation for a 
  \c \#define macro. 

  \par Example:
  \verbinclude define.h  
  \htmlonly
  Click <a href="$(DOXYGEN_DOCDIR)/examples/define/html/define_8h.html">here</a> 
  for the corresponding HTML documentation that is generated by doxygen.
  \endhtmlonly

<hr>
\section cmddefgroup \\defgroup <name> (group title)

  \addindex \\defgroup
  Indicates that a comment block contains documentation for a
  \ref modules "group" of classes, files or namespaces. This can be used to
  categorize classes, files or namespaces, and document those
  categories. You can also use groups as members of other groups,
  thus building a hierarchy of groups.

  The \<name\> argument should be a single-word identifier.
  
  \sa page \ref grouping "Grouping", sections \ref cmdingroup "\\ingroup", \ref cmdaddtogroup "\\addtogroup",
  \ref cmdweakgroup "\\weakgroup".

<hr>
\section cmddir \\dir [<path fragment>]
  
  \addindex \\dir
  Indicates that a comment block contains documentation for a directory.
  The "path fragment" argument should include the directory name and 
  enough of the path to be unique w.r.t. the other directories in the project.
  The \ref cfg_show_dirs "SHOW_DIRECTORIES" option determines whether 
  or not the directory information is shown and the
  \ref cfg_strip_from_path "STRIP_FROM_PATH" option determines what is 
  stripped from the full path before it appears in the output.

<hr>

\section cmdenum \\enum <name>

  \addindex \\enum
  Indicates that a comment block contains documentation for an 
  enumeration, with name \<name\>. If the enum is a member of a class and
  the documentation block is located outside the class definition,
  the scope of the class should be specified as well.
  If a comment block is located directly in front of an enum declaration,
  the \\enum comment may be omitted.

  \par Note:
  The type of an anonymous enum cannot be documented, but the values 
  of an anonymous enum can.
  
  \par Example:
  \verbinclude enum.h  
  \htmlonly
  Click <a href="$(DOXYGEN_DOCDIR)/examples/enum/html/class_test.html">here</a> 
  for the corresponding HTML documentation that is generated by doxygen.
  \endhtmlonly

<hr>
\section cmdexample \\example <file-name>
  
  \addindex \\example
  Indicates that a comment block contains documentation for a source code 
  example. The name of the source file is \<file-name\>. The text of
  this file will be included in the documentation, just after the 
  documentation contained in the comment block. All examples are placed
  in a list. The source code is scanned for documented members and classes.
  If any are found, the names are cross-referenced with the documentation. 
  Source files or directories can be specified using the 
  \ref cfg_example_path "EXAMPLE_PATH" 
  tag of doxygen's configuration file.

  If \<file-name\> itself is not unique for the set of example files specified
  by the 
  \ref cfg_example_path "EXAMPLE_PATH" tag, you can include part of the absolute path
  to disambiguate it.

  If more that one source file is needed for the example,
  the \\include command can be used.

  \par Example:
  \verbinclude example.cpp
  Where the example file \c example_test.cpp looks as follows:
  \verbinclude example_test.cpp
  \htmlonly
  Click <a href="$(DOXYGEN_DOCDIR)/examples/example/html/examples.html">here</a> 
  for the corresponding HTML documentation that is generated by doxygen.
  \endhtmlonly

  \sa section \ref cmdinclude "\\include".

<hr>
\section cmdfile \\file [<name>]
  
  \addindex \\file
  Indicates that a comment block contains documentation for a source or 
  header file with name \<name\>. The file name may include (part of) the
  path if the file-name alone is not unique. If the file name is omitted
  (i.e. the line after \\file is left blank) then the documentation block that 
  contains the \\file command will belong to the file it is located in.

  \par Important:
  The documentation of global functions, variables, typedefs, and enums will 
  only be included in the output if the file they are in is documented as well.

  \par Example:
  \verbinclude file.h  
  \htmlonly
  Click <a href="$(DOXYGEN_DOCDIR)/examples/file/html/file_8h.html">here</a> 
  for the corresponding HTML documentation that is generated by doxygen.
  \endhtmlonly

  \note In the above example \ref cfg_javadoc_autobrief "JAVADOC_AUTOBRIEF"
  has been set to YES in the configuration file.

<hr>
\section cmdfn \\fn (function declaration)
 
  \addindex \\fn
  Indicates that a comment block contains documentation for a function
  (either global or as a member of a class). This command is \em only 
  needed if a comment block is \e not placed in front (or behind) 
  the function declaration or definition. 
  
  If your comment block \e is in front of the function 
  declaration or definition this command can (and to avoid redundancy
  should) be omitted. 

  A full function declaration including arguments should be specified after the
  \\fn command on a \e single line, since the argument ends at the end 
  of the line!

  \warning Do not use this command
  if it is not absolutely needed, since it will lead to duplication of 
  information and thus to errors.

  \par Example:
  \verbinclude func.h  
  \htmlonly
  Click <a href="$(DOXYGEN_DOCDIR)/examples/func/html/class_test.html">here</a> 
  for the corresponding HTML documentation that is generated by doxygen.
  \endhtmlonly


  \sa section \ref cmdvar "\\var" and \ref cmdtypedef "\\typedef".

<hr>
\section cmdhideinitializer \\hideinitializer

  \addindex \\hideinitializer
  By default the value of a define and the initializer of a variable
  are displayed unless they are longer than 30 lines. By putting
  this command in a comment block of a define or variable, the 
  initializer is always hidden.

  \sa section \ref cmdshowinitializer "\\showinitializer".

<hr>
\section cmdingroup \\ingroup (<groupname> [<groupname> <groupname>])

  \addindex \\ingroup
  If the \\ingroup command is placed in a comment block of a
  class, file or namespace, then it will be added to the group or
  groups identified by \<groupname\>.

  \sa page \ref grouping "Grouping", sections \ref cmddefgroup "\\defgroup",
  \ref cmdaddtogroup "\\addtogroup" and \ref cmdweakgroup "\\weakgroup"

<hr>
\section cmdinterface \\interface <name> [<header-file>] [<header-name>]

  \addindex \\interface
  Indicates that a comment block contains documentation for an
  interface with name \<name\>. The arguments are equal to the \\class
  command.

  \sa section \ref cmdclass "\\class".

<hr>
\section cmdinternal \\internal
  
  \addindex \\internal
  This command writes the message `For internal use only' to the output and
  all text \e after an \c \\internal command until the end of the
  comment block or the end of the section (whichever comes first) is 
  marked as "internal". 

  If the \\internal command is put inside a section 
  (see for example \ref cmdsection "\\section") all subsection after the 
  command are considered to be internal as well. Only a new section at the 
  same level will be visible again. 

  You can use \ref cfg_internal_docs "INTERNAL_DOCS" in the config file
  to show or hide the internal documentation.

<hr>
\section cmdmainpage \\mainpage [(title)]

  \addindex \\mainpage

  If the \\mainpage command is placed in a comment block the 
  block is used to customize the index page (in HTML) or
  the first chapter (in \f$\mbox{\LaTeX}\f$). 

  The title argument is optional and replaces the default title that
  doxygen normally generates. If you do not want any title you can
  specify \c notitle as the argument of \\mainpage.

  Here is an example:
\verbatim
/*! \mainpage My Personal Index Page
 *
 * \section intro_sec Introduction
 *
 * This is the introduction.
 *
 * \section install_sec Installation
 *
 * \subsection step1 Step 1: Opening the box
 *  
 * etc...
 */
\endverbatim

 You can refer to the main page using \\ref index (if the treeview
 is disabled, otherwise you should use \\ref main).

 \sa section \ref cmdsection "\\section", 
     section \ref cmdsubsection "\\subsection" and 
     section \ref cmdpage "\\page".

<hr>
\section cmdname \\name (header)  

This command turns a comment block into a header
definition of a member group. The
comment block should be followed by a 
<code>//\@{ ... //\@}</code> block containing the
members of the group.

See section \ref memgroup for an example.

<hr>
\section cmdnamespace \\namespace <name> 

  \addindex \\namespace
  Indicates that a comment block contains documentation for a
  namespace with name \<name\>. 
  
<hr>
\section cmdnosubgrouping \\nosubgrouping

  \addindex \\nosubgrouping
  This command can be put in the documentation
  of a class. It can be used in combination with member grouping
  to avoid that doxygen puts a member group as a subgroup of a
  Public/Protected/Private/... section.

<hr>
\section cmdoverload \\overload [(function declaration)]

  \addindex \\overload
  This command can be used to generate the following 
  standard text for an overloaded member function:

   `This is an overloaded member function, provided for convenience. 
    It differs from the above function only in what argument(s) it accepts.'

  If the documentation for the overloaded member function is not located
  in front of the function declaration or definition, the optional 
  argument should be used to specify the correct function.
 
  Any other documentation that is inside the documentation block will
  by appended after the generated message.

  \par Note 1:
    You are responsible that there is indeed an
    earlier documented member that is overloaded by this one.
    To prevent that document reorders the documentation you should set
    \ref cfg_sort_member_docs "SORT_MEMBER_DOCS" to NO in this case.
  \par Note 2:
    The \\overload command does not work inside a one-line comment.
  \par Example:
  \verbinclude examples/overload.cpp
  \htmlonly
  Click <a href="$(DOXYGEN_DOCDIR)/examples/overload/html/class_test.html">here</a> 
  for the corresponding HTML documentation that is generated by doxygen.
  \endhtmlonly

<hr>
\section cmdpackage \\package <name>
  
  \addindex \\package
  Indicates that a comment block contains documentation for a
  Java package with name \<name\>. 

<hr>
\section cmdpage \\page <name> (title)

  \addindex \\page
  Indicates that a comment block contains a piece of documentation that is
  not directly related to one specific class, file or member. 
  The HTML generator creates a page containing the documentation. The
  \f$\mbox{\LaTeX}\f$ generator 
  starts a new section in the chapter `Page documentation'.
  
  \par Example:
  \verbinclude page.doc  
  \htmlonly
  Click <a href="$(DOXYGEN_DOCDIR)/examples/page/html/pages.html">here</a> 
  for the corresponding HTML documentation that is generated by doxygen.
  \endhtmlonly

  \par Note: 
     The \<name\> argument consists of a combination of letters and number
     digits. If you wish to use upper case letters (e.g. \c MYPAGE1), or 
     mixed case letters (e.g. \c MyPage1) in the \<name\> argument, you 
     should set \c CASE_SENSE_NAMES to \c YES. However, this is advisable 
     only if your file system is case sensitive. Otherwise (and for better 
     portability) you should use all lower case letters (e.g. \c mypage1) 
     for \<name\> in all references to the page.
  
  \sa section \ref cmdsection "\\section", section 
              \ref cmdsubsection "\\subsection", and section 
              \ref cmdref "\\ref".

<hr>
\section cmdproperty \\property (qualified property name)

  \addindex \\property
  Indicates that a comment block contains documentation for a
  property (either global or as a member of a class). 
  This command is equivalent to \\var and \\fn.

  \sa section \ref cmdfn "\\fn" and \ref cmdvar "\\var".

<hr>
\section cmdprotocol \\protocol <name> [<header-file>] [<header-name>]

  \addindex \\protocol
  Indicates that a comment block contains documentation for a
  protocol in Objective-C with name \<name\>. The arguments are equal 
  to the \\class command.

  \sa section \ref cmdclass "\\class".

<hr>
\section cmdrelates \\relates <name>

  \addindex \\relates
  This command can be used in the documentation of a non-member function
  \<name\>. It puts the function inside the `related function' section 
  of the class documentation. This command is useful for documenting 
  non-friend functions that are nevertheless strongly coupled to a certain
  class. It prevents the need of having to document a file, but
  only works for functions.  

  \par Example:
  \verbinclude relates.cpp  
  \htmlonly
  Click <a href="$(DOXYGEN_DOCDIR)/examples/relates/html/class_string.html">here</a> 
  for the corresponding HTML documentation that is generated by doxygen.
  \endhtmlonly

<hr>
\section cmdrelatesalso \\relatesalso <name>

  \addindex \\relatesalso
  This command can be used in the documentation of a non-member function
  \<name\>. It puts the function both inside the `related function' section 
  of the class documentation as well as leaving its normal file documentation
  location. This command is useful for documenting 
  non-friend functions that are nevertheless strongly coupled to a certain
  class. It only works for functions.  

<hr>
\section cmdshowinitializer \\showinitializer

  \addindex \\showinitializer
  By default the value of a define and the initializer of a variable
  are only displayed if they are less than 30 lines long. By putting
  this command in a comment block of a define or variable, the 
  initializer is shown unconditionally.

  \sa section \ref cmdhideinitializer "\\hideinitializer".

<hr>
\section cmdstruct \\struct <name> [<header-file>] [<header-name>]

  \addindex \\struct
  Indicates that a comment block contains documentation for a
  struct with name \<name\>. The arguments are equal to the \\class
  command.

  \sa section \ref cmdclass "\\class".

<hr>
\section cmdtypedef \\typedef (typedef declaration)

  \addindex \\typedef
  Indicates that a comment block contains documentation for a
  typedef (either global or as a member of a class). 
  This command is equivalent to \\var and \\fn.

  \sa section \ref cmdfn "\\fn" and \ref cmdvar "\\var".

<hr>
\section cmdunion \\union <name> [<header-file>] [<header-name>]

  \addindex \\union
  Indicates that a comment block contains documentation for a
  union with name \<name\>. The arguments are equal to the \\class
  command.

  \sa section \ref cmdclass "\\class".

<hr>
\section cmdvar \\var (variable declaration)

  \addindex \\var
  Indicates that a comment block contains documentation for a variable or
  enum value (either global or as a member of a class). 
  This command is equivalent to \\typedef and \\fn.

  \sa section \ref cmdfn "\\fn" and \ref cmdtypedef "\\typedef".

<hr>
\section cmdweakgroup \\weakgroup <name> [(title)]
  \addindex \\addtogroup
  Can be used exactly like \ref cmdaddtogroup "\\addtogroup", but has
  a lower priority when it comes to resolving conflicting grouping
  definitions.

  \sa page \ref grouping "Grouping" and \ref cmdaddtogroup "\\addtogroup".

<hr>

<h2>\htmlonly <center> --- \endhtmlonly 
    Section indicators
    \htmlonly --- </center>\endhtmlonly</h2>

<hr>
\section cmdattention \\attention { attention text }

  \addindex \\attention
  Starts a paragraph where a message that needs attention may be entered. 
  The paragraph will be indented. 
  The text of the paragraph has no special internal structure. All visual
  enhancement commands may be used inside the paragraph.
  Multiple adjacent \\attention commands will be joined into a single paragraph.
  The \\attention command ends when a blank line or some other 
  sectioning command is encountered. 

\section cmdauthor \\author { list of authors }

  \addindex \\author
  Starts a paragraph where one or more author names may be entered. 
  The paragraph will be indented. 
  The text of the paragraph has no special internal structure. All visual
  enhancement commands may be used inside the paragraph.
  Multiple adjacent \\author commands will be joined into a single paragraph
  and separated by commas. Alternatively, one \\author command may mention 
  several authors. The \\author command ends when a blank line or some other 
  sectioning command is encountered.

  \par Example:
  \verbinclude author.cpp  
  \htmlonly
  Click <a href="$(DOXYGEN_DOCDIR)/examples/author/html/class_windows_n_t.html">here</a> 
  for the corresponding HTML documentation that is generated by doxygen.
  \endhtmlonly

<hr>
\section cmdbrief \\brief {brief description}

  \addindex \\brief
  Starts a paragraph that serves as a brief description. For classes and files
  the brief description will be used in lists and at the start of the
  documentation page. For class and file members, the brief description
  will be placed at the declaration of the member and prepended to the
  detailed description. A brief description may span several lines (although
  it is advised to keep it brief!). A brief description ends when a 
  blank line or another sectioning command is encountered. If multiple
  \\brief commands are present they will be joined. See section 
  \ref cmdauthor "\\author" for an example. 

  Synonymous to \\short.
 
<hr>
\section cmdbug \\bug { bug description }

  \addindex \\bug
  Starts a paragraph where one or more bugs may be reported. 
  The paragraph will be indented. 
  The text of the paragraph has no special internal structure. All visual
  enhancement commands may be used inside the paragraph.
  Multiple adjacent \\bug commands will be joined into a single paragraph.
  Each bug description will start on a new line.
  Alternatively, one \\bug command may mention 
  several bugs. The \\bug command ends when a blank line or some other 
  sectioning command is encountered. See section \ref cmdauthor "\\author"
  for an example.

<hr>
\section cmdcond \\cond [<section-label>]

  \addindex \\cond
  Starts a conditional section that ends with a corresponding 
  \ref cmdendcond "\\endcond" command, which is typically found in 
  another comment block. The main purpose of this pair of
  commands is to (conditionally) exclude part of a file from processing
  (in older version of doxygen this could only be achieved using C preprocessor commands). 

  The section between \\cond and \\endcond commands can be included by
  adding its section label to the \ref cfg_enabled_sections "ENABLED_SECTIONS"
  configuration option. If the section label is omitted, the section will
  be excluded from processing unconditionally.

  For conditional sections within a comment block one should 
  use a \ref cmdif "\\if" ... \ref cmdendif "\\endif" block.

  Conditional sections can be nested. In this case a nested section will only
  be shown if it and its containing section are included.

  Here is an example showing the commands in action:

\verbatim
/** An interface */
class Intf
{
  public:
    /** A method */
    virtual void func() = 0;

    /// @cond TEST

    /** A method used for testing */
    virtual void test() = 0;

    /// @endcond
};

/// @cond DEV
/*
 *  The implementation of the interface 
 */
class Implementation : public Intf
{
  public:
    void func();

    /// @cond TEST
    void test();
    /// @endcond

    /// @cond
    /** This method is obsolete and does
     *  not show up in the documentation.
     */
    void obsolete();
    /// @endcond
};

/// @endcond 
\endverbatim

The output will be different depending on whether or not \c ENABLED_SECTIONS
contains \c TEST, or \c DEV

<hr>
\section cmddate \\date { date description }

  \addindex \\date
  Starts a paragraph where one or more dates may be entered. 
  The paragraph will be indented. 
  The text of the paragraph has no special internal structure. All visual
  enhancement commands may be used inside the paragraph.
  Multiple adjacent \\date commands will be joined into a single paragraph.
  Each date description will start on a new line.
  Alternatively, one \\date command may mention 
  several dates. The \\date command ends when a blank line or some other 
  sectioning command is encountered. See section \ref cmdauthor "\\author" 
  for an example.

<hr>
\section cmddeprecated \\deprecated { description }

  \addindex \\deprecated
  Starts a paragraph indicating that this documentation block belongs to
  a deprecated entity. Can be used to describe alternatives, 
  expected life span, etc.

<hr>
\section cmddetails \\details {detailed decription}

  \addindex \\details
  Just like \ref cmdbrief "\\brief" starts a brief description, \\details
  starts the detailed description. You can also start a new paragraph (blank line)
  then the \\details command is not needed.

<hr>
\section cmdelse \\else 

  \addindex \\else
  Starts a conditional section if the previous conditional section 
  was not enabled. The previous section should have been started with 
  a \c \\if, \c \\ifnot, or \c \\elseif command.

  \sa \ref cmdif "\\if", \ref cmdifnot "\\ifnot", \ref cmdelseif "\\elseif",
      \ref cmdendif "\\endif."

<hr>
\section cmdelseif \\elseif <section-label>

  \addindex \\elseif
  Starts a conditional documentation section if the previous section 
  was not enabled. A conditional section is
  disabled by default. To enable it you must put the
  section-label after the \ref cfg_enabled_sections "ENABLED_SECTIONS" 
  tag in the configuration
  file. Conditional blocks can be nested. A nested section is
  only enabled if all enclosing sections are enabled as well.

  \sa sections \ref cmdendif "\\endif", \ref cmdifnot "\\ifnot", 
              \ref cmdelse "\\else", and \ref cmdelseif "\\elseif".

<hr>
\section cmdendcond \\endcond

  \addindex \\endcond
  Ends a conditional section that was started by \ref cmdcond "\\cond".

  \sa \ref cmdcond "\\cond".

<hr>
\section cmdendif \\endif 

  \addindex \\endif
  Ends a conditional section that was started by \c \\if or \c \\ifnot
  For each \c \\if or \c \\ifnot one and only one matching \c \\endif must follow.

  \sa \ref cmdif "\\if", and \ref cmdifnot "\\ifnot".

<hr>
\section cmdexception \\exception <exception-object> { exception description }

  \addindex \\exception
  Starts an exception description for an exception object with name 
  \<exception-object\>. Followed by a description of the exception. 
  The existence of the exception object is not checked.
  The text of the paragraph has no special internal structure. All visual
  enhancement commands may be used inside the paragraph.
  Multiple adjacent \\exception commands will be joined into a single paragraph.
  Each parameter description will start on a new line.
  The \\exception description ends when a blank line or some other 
  sectioning command is encountered. See section \ref cmdfn "\\fn" for an 
  example.

  \par Note: 
  the tag \\exceptions is a synonym for this tag.

<hr>
\section cmdif \\if <section-label>

  \addindex \\if
  Starts a conditional documentation section. The section ends 
  with a matching \c \\endif command. A conditional section is
  disabled by default. To enable it you must put the
  section-label after the \ref cfg_enabled_sections "ENABLED_SECTIONS" 
  tag in the configuration
  file. Conditional blocks can be nested. A nested section is
  only enabled if all enclosing sections are enabled as well.

  \par Example:
\verbatim
  /*! Unconditionally shown documentation.
   *  \if Cond1
   *    Only included if Cond1 is set.
   *  \endif
   *  \if Cond2
   *    Only included if Cond2 is set.
   *    \if Cond3
   *      Only included if Cond2 and Cond3 are set.
   *    \endif
   *    More text.
   *  \endif
   *  Unconditional text.
   */
\endverbatim  

  You can also use conditional commands inside aliases. To 
  document a class in two languages you could for instance use:

\par Example 2:
\verbatim
/*! \english
 *  This is English.
 *  \endenglish
 *  \dutch
 *  Dit is Nederlands.
 *  \enddutch
 */
class Example
{
};
\endverbatim
  <p>Where the following aliases are defined in the configuration file:<p>
\verbatim
ALIASES  = "english=\if english" \
           "endenglish=\endif" \
           "dutch=\if dutch" \
           "enddutch=\endif"
\endverbatim

  and \c ENABLED_SECTIONS can be used to enable either \c english or \c dutch.

\section cmdparam \\param <parameter-name> { parameter description }

  \addindex \\param
  Starts a parameter description for a function parameter with name 
  \<parameter-name\>. Followed by a description of the parameter. 
  The existence of the parameter is checked and a warning is given if
  the documentation of this (or any other) parameter is missing or not
  present in the function declaration or definition.

  The \\param command has an optional attribute specifying the direction
  of the attribute. Possible values are "in" and "out". Here is an example
  for the function memcpy:
  \code
/*!
 * Copies bytes from a source memory area to a destination memory area,
 * where both areas may not overlap.
 * @param[out] dest The memory area to copy to.
 * @param[in]  src  The memory area to copy from.
 * @param[in]  n    The number of bytes to copy
 */
void memcpy(void *dest, const void *src, size_t n);
  \endcode
  If a parameter is both input and output, use [in,out] as an attribute.

  The parameter description is a paragraph with no special internal structure. 
  All visual enhancement commands may be used inside the paragraph.

  Multiple adjacent \\param commands will be joined into a single paragraph.
  Each parameter description will start on a new line.

\section cmdxrefitem \\xrefitem <key> "(heading)" "(list title)" {text}

 \addindex \\xrefitem
 This command is a generalization of commands such as \ref cmdtodo "\\todo" 
 and \ref cmdbug "\\bug".
 It can be used to create user-defined text sections which are automatically 
 cross-referenced between the place of occurrence and a related page, 
 which will be generated. On the related page all sections of 
 the same type will be collected. 
 
 The first argument \<key\> is a
 identifier uniquely representing the type of the section. The second argument 
 is a quoted string representing the heading of the section under which 
 text passed as the forth argument is put. The third argument (list title)
 is used as the title for the related page containing all items with the 
 same key. The keys "todo", "test", "bug", and "deprecated" are predefined.
 
 To get an idea on how to use the \\xrefitem command and what its effect 
 is, consider the todo list, which (for English output) can be seen an 
 alias for the command
 \verbatim \xrefitem todo "Todo" "Todo List" \endverbatim

 Since it is very tedious and error-prone to repeat the first three 
 parameters of the command for each section, the command is meant to 
 be used in combination with the \ref cfg_aliases "ALIASES" option in the 
 configuration file.
 To define a new command \\reminder, for instance, one should add the following
 line to the configuration file:
 \verbatim ALIASES += "reminder=\xrefitem reminders \"Reminder\" \"Reminders\"" \endverbatim
 Note the use of escaped quotes for the second and third argument of the
 \\xrefitem command.

  This command ends a link that is started with the \\link command.
  
  \sa section \ref cmdlink "\\link".

<hr>
\section cmdlink \\link <link-object> 

  \addindex \\link
  The links that are automatically generated by doxygen always have the
  name of the object they point to as link-text. 

  The \\link command can be used to create a link to an object (a file, 
  class, or member) with a user specified link-text. 
  The link command should end with an \\endlink command. All text between
  the \\link and \\endlink commands serves as text for a link to 
  the \<link-object\> specified as the first argument of \\link.
  
  See section \ref autolink "autolink" for more information on automatically 
  generated links and valid link-objects.

<hr>
\section cmdref \\ref <name> ["(text)"]

  \addindex \\ref
  Creates a reference to a named section, subsection, page or anchor.
  For HTML documentation the reference command will generate a link to 
  the section. For a sections or subsections the title of the section will be 
  used as the text of the link. For anchor the optional text between quotes
  will be used or \<name\> if no text is specified.
  For \f$\mbox{\LaTeX}\f$ documentation the reference command will 
  generate a section number for sections or the text followed by a 
  page number if \<name\> refers to an anchor.

  \sa
    Section \ref cmdpage "\\page" for an example of the \\ref command.

<hr>
\section cmdsubpage \\subpage <name> ["(text)"]

  \addindex \\subpage
  This command can be used to create a hierarchy of pages. The
  same structure can be made using the \ref cmddefgroup "\\defgroup" and
  \ref cmdingroup "\\ingroup" commands, but for pages the \\subpage command
  is often more convenient. The main page (see \ref cmdmainpage "\\mainpage") 
  is typically the root of hierarchy. 

  This command behaves similar as \ref cmdref "\\ref" in the sense that
  it creates a reference to a page labeled \<name\> with the optional
  link text as specified in the second argument. 

  It differs from the \\ref command in that it only works for pages,
  and creates a parent-child relation between pages, where the
  child page (or sub page) is identified by label \<name\>. 
  
  See the \ref cmdsection "\\section"
  and \ref cmdsubsection "\\subsection" commands if you want to add structure
  without creating multiple pages.

  \note Each page can be the sub page of only one other page and
  no cyclic relations are allowed, i.e. the page hierarchy must have a tree 
  structure.
  
  Here is an example:
\verbatim

\section cmddontinclude \\dontinclude <file-name>

  \addindex \\dontinclude
  This command can be used to parse a source file without actually 
  verbatim including it in the documentation (as the \\include command does). 
  This is useful if you want to divide the source file into smaller pieces and
  add documentation between the pieces.
  Source files or directories can be specified using the 
  \ref cfg_example_path "EXAMPLE_PATH" 
  tag of doxygen's configuration file.

  The class and member declarations and definitions inside the code fragment
  are `remembered' during the parsing of the comment block that contained 
  the \\dontinclude command. 

  For line by line descriptions of source files, one or more lines 
  of the example can be displayed using the \\line, \\skip, \\skipline, and 
  \\until commands. An internal pointer is used for these commands. The
  \\dontinclude command sets the pointer to the first line of the example.

  \par Example:
  \verbinclude include.cpp
  Where the example file \c example_test.cpp looks as follows:
  \verbinclude example_test.cpp
  \htmlonly
  Click <a href="$(DOXYGEN_DOCDIR)/examples/include/html/example.html">here</a> 
  for the corresponding HTML documentation that is generated by doxygen.
  \endhtmlonly

               \ref cmdskipline "\\skipline", and \ref cmduntil "\\until".

<hr>
\section cmdinclude \\include <file-name>

  \addindex \\include
  This command can be used to include a source file as a block of code.
  The command takes the name of an include file as an argument. 
  Source files or directories can be specified using the 
  \ref cfg_example_path "EXAMPLE_PATH" 
  tag of doxygen's configuration file.

  If \<file-name\> itself is not unique for the set of example files specified
  by the \ref cfg_example_path "EXAMPLE_PATH" tag, you can include part 
  of the absolute path to disambiguate it.

  Using the \\include command is equivalent to inserting the file into 
  the documentation block and surrounding it 
  with \ref cmdcode "\\code" and \ref cmdendcode "\\endcode" commands.

  The main purpose of the \\include command is to avoid code 
  duplication in case of example blocks that consist of multiple
  source and header files.

  For a line by line description of a source files use the 
  \ref cmddontinclude "\\dontinclude" command in combination with 
  the \ref cmdline "\\line", \ref cmdskip "\\skip", 
  \ref cmdskipline "\\skipline", 
  and \\until commands.  

  \note Doxygen's special commands do not work inside blocks of code. 
  It is allowed to nest C-style comments inside a code block though.

<hr>
\section cmdline \\line ( pattern )

  \addindex \\line
  This command searches line by line through the example that was last
  included using \\include or \\dontinclude until it finds a non-blank
  line. If that line contains the specified pattern, it is written 
  to the output.
  
  The internal pointer that is used to keep track of the current line in
  the example, is set to the start of the line following the non-blank
  line that was found (or to the end of the example if no such line could
  be found).

  See section \ref cmddontinclude "\\dontinclude" for an example.

<hr>
\section cmdskip \\skip ( pattern )

  \addindex \\skip
  This command searches line by line through the example that was last
  included using \\include or \\dontinclude until it finds a line that contains
  the specified pattern. 
  
  The internal pointer that is used to keep track of the current line in
  the example, is set to the start of the line that contains the specified
  pattern (or to the end of the example if the pattern could not be found). 

  See section \ref cmddontinclude "\\dontinclude" for an example.

<hr>
\section cmdskipline \\skipline ( pattern ) 

  \addindex \\skipline
  This command searches line by line through the example that was last
  included using \\include or \\dontinclude until it finds a line that contains
  the specified pattern. It then writes the line to the output.
  
  The internal pointer that is used to keep track of the current line in
  the example, is set to the start of the line following the line that is
  written (or to the end of the example if the pattern could not be found). 

  \par Note:
    The command:
    \verbatim\skipline pattern\endverbatim 
    is equivalent to:
\verbatim
\skip pattern
\line pattern\endverbatim

  See section \ref cmddontinclude "\\dontinclude" for an example.

<hr>
\section cmduntil \\until ( pattern )

  \addindex \\until
  This command writes all lines of the example that was last
  included using \\include or \\dontinclude to the output, until it finds 
  a line containing the specified pattern. The line containing the pattern
  will be written as well.
  
  The internal pointer that is used to keep track of the current line in
  the example, is set to the start of the line following last written
  line (or to the end of the example if the pattern could not be found).

  See section \ref cmddontinclude "\\dontinclude" for an example.

<hr>
\section cmdverbinclude \\verbinclude <file-name>

  \addindex \\verbinclude
  This command includes the file \<file-name\> verbatim in the documentation.
  The command is equivalent to pasting the file in the documentation and

  Files or directories that doxygen should look for can be specified using the 
  \ref cfg_example_path "EXAMPLE_PATH" tag of doxygen's configuration file.

<hr>
\section cmdhtmlinclude \\htmlinclude <file-name>

  \addindex \\htmlinclude
  This command includes the file \<file-name\> as is in the HTML documentation.

<hr>
\section cmdcopydoc \\copydoc <link-object>

  \addindex \\copydoc
  Copies a documentation block from the object specified by \<link-object\>
  and pastes it at the location of the command. This command can be useful 
  to avoid cases where a documentation block would otherwise have to be 
  duplicated or it can be used to extend the documentation of an inherited 
  member.
  
  The link object can point to a member (of a class, file or group), 
  a class, a namespace, a group, a page, or a file (checked in that order). 
  Note that if the object pointed to is a member (function, variable, 
  typedef, etc), the compound (class, file, or group) containing it 
  should also be documented for the copying to work. 

  To copy the documentation for a member of a 
  class for instance one can put the following in the documentation

\verbatim
  /*! @copydoc MyClass::myfunction() 
   *  More documentation.
   */
\endverbatim

  if the member is overloaded, you should specify the argument types 
  explicitly (without spaces!), like in the following:

\verbatim
  /*! @copydoc MyClass::myfunction(type1,type2) */
\endverbatim

  Qualified names are only needed if the context in which the documentation
  block is found requires them.

  The copydoc command can be used recursively, but cycles in the copydoc
  relation will be broken and flagged as an error.

\section cmddot \\dot

  \addindex \\dot
  Starts a text fragment which should contain a valid description of a
  dot graph. The text fragment ends with \ref cmdenddot "\\enddot". 
  Doxygen will pass the text on to dot and include the resulting 
  image (and image map) into the output.
  The nodes of a graph can be made clickable by using the URL attribute.
  By using the command \\ref inside the URL value you can conveniently 
  link to an item inside doxygen. Here is an example:
\code
/*! class B */
class B {};

/*! class C */
class C {};

/*! \mainpage
 *
 *  Class relations expressed via an inline dot graph:
 *  \dot
 *  digraph example {
 *      node [shape=record, fontname=Helvetica, fontsize=10];
 *      b [ label="class B" URL="\ref B"];
 *      c [ label="class C" URL="\ref C"];
 *      b -> c [ arrowhead="open", style="dashed" ];
 *  }
 *  \enddot
 *  Note that the classes in the above graph are clickable 
 *  (in the HTML output).
 */
\endcode
  
<hr>
\section cmdmsc \\msc

  \addindex \\msc
  Starts a text fragment which should contain a valid description of a
  message sequence chart. See http://www.mcternan.me.uk/mscgen/ for examples.
  The text fragment ends with \ref cmdendmsc "\\endmsc". 
  \note The text fragment should only include the part of the message 
  sequence chart that is
  within the <code>msc {...}</code> block.
  \note You need to install the <code>mscgen</code> tool, if you want to use this
  command. 

Here is an example of the use of the \\msc command.
\code
/** Sender class. Can be used to send a command to the server.
 *  The receiver will acknowlegde the command by calling Ack().
 *  \msc
 *    Sender,Receiver;
 *    Sender->Receiver [label="Command()", URL="\ref Receiver::Command()"];
 *    Sender<-Receiver [label="Ack()", URL="\ref Ack()", ID="1"];
 *  \endmsc
 */
class Sender
{
  public:
    /** Acknowledgement from server */
    void Ack(bool ok);
};

/** Receiver class. Can be used to receive and execute commands.
 *  After execution of a command, the receiver will send an acknowledgement
 *  \msc
 *    Receiver,Sender;
 *    Receiver<-Sender [label="Command()", URL="\ref Command()"];
 *    Receiver->Sender [label="Ack()", URL="\ref Sender::Ack()", ID="1"];
 *  \endmsc
 */
class Receiver
{
  public:
    /** Executable a command on the server */
    void Command(int commandId);
};

\endcode  

<hr>
\section cmddotfile \\dotfile <file> ["caption"] 

  \addindex \\dotfile
  Inserts an image generated by dot from \<file\> into the documentation. 

  The first argument specifies the file name of the image. 
  doxygen will look for files in the paths (or files) that you specified 
  after the \ref cfg_dotfile_dirs "DOTFILE_DIRS" tag. 
  If the dot file is found it will be used as an input file to the dot tool. 
  The resulting image will be put into the correct output directory.
  If the dot file name contains spaces you'll have to put quotes (") around it.

  The second argument is optional and can be used to specify the caption
  that is displayed below the image. This argument has to be specified
  between quotes even if it does not contain any spaces. The quotes are
  stripped before the caption is displayed.

<hr>
\section cmde \\e <word>

  \addindex \\e 
  Displays the argument \<word\> in italics.
  Use this command to emphasize words.

  \par Example:
  Typing:
  \verbatim
  ... this is a \e really good example ... 
  \endverbatim
  will result in the following text:<br><br>
  ... this is a \e really good example ...

  Equivalent to \ref cmdem "\\em". 
  To emphasis multiple words use \<em\>multiple words\</em\>.

<hr>
\section cmdem \\em <word>

  \addindex \\em 
  Displays the argument \<word\> in italics.
  Use this command to emphasize words.

  \par Example:
  Typing:

  Marks the start and end of an in-text formula. 
  \sa section \ref formulas "formulas" for an example.
  
<hr>
\section cmdfbropen \\f[

  \addindex \\f[

  Marks the start of a long formula that is displayed 
  centered on a separate line.
  \sa section \ref cmdfbrclose "\\f]" and section \ref formulas "formulas".

<hr>
\section cmdfbrclose \\f]

  \sa section \ref cmdfbropen "\\f[" and section \ref formulas "formulas".

<hr>
\section cmdhtmlonly \\htmlonly

  \addindex \\htmlonly
  Starts a block of text that will be verbatim included in the
  generated HTML documentation only. The block ends with a
  endhtmlonly command.

  This command can be used to include HTML code that is too complex
  for doxygen (i.e. applets, java-scripts, and HTML tags that
  require attributes). You can use the \\latexonly and \\endlatexonly
  pair to provide a proper \f$\mbox{\LaTeX}\f$ alternative.

  \b Note:
    environment variables (like \$(HOME) ) are resolved inside a 
    HTML-only block.

  \sa section \ref cmdmanonly "\\manonly" and section 
              \ref cmdlatexonly "\\latexonly".

<hr>
\section cmdimage \\image <format> <file> ["caption"] [<sizeindication>=<size>]

  \addindex \\image
  Inserts an image into the documentation. This command is format
  specific, so if you want to insert an image for more than one
  format you'll have to repeat this command for each format.

  The first argument specifies the output format. Currently, the 
  following values are supported: \c html and \c latex.
  
  The second argument specifies the file name of the image. 
  doxygen will look for files in the paths (or files) that you specified 
  after the \ref cfg_image_path "IMAGE_PATH" tag. 
  If the image is found it will be copied to the correct output directory.
  If the image name contains spaces you'll have to put quotes (") around it.
  You can also specify an absolute URL instead of a file name, but then
  doxygen does not copy the image nor check its existance.

  The third argument is optional and can be used to specify the caption
  that is displayed below the image. This argument has to be specified
  on a single line and between quotes even if it does not contain any 
  spaces. The quotes are stripped before the caption is displayed.

  The fourth argument is also optional and can be used to specify the 
  width or height of the image. This is only useful 
  for \f$\mbox{\LaTeX}\f$ output
  (i.e. format=<code>latex</code>). The \c sizeindication can be 
  either \c width or \c height. The size should be a valid 
  size specifier in \f$\mbox{\LaTeX}\f$ (for example <code>10cm</code> or 
  <code>6in</code> or a symbolic width like <code>\\textwidth</code>).

  Here is example of a comment block:

\verbatim
  /*! Here is a snapshot of my new application:
   *  \image html application.jpg
   *  \image latex application.eps "My application" width=10cm
   */
\endverbatim

  And this is an example of how the relevant part of the configuration file 
  may look:

\verbatim
  IMAGE_PATH     = my_image_dir
\endverbatim

  \warning The image format for HTML is limited to what your
           browser supports. For \f$\mbox{\LaTeX}\f$, the image format
           must be Encapsulated PostScript (eps).
           <br><br>
           Doxygen does not check if the image is in the correct format. 
           So \e you have to make sure this is the case!

<hr>
\section cmdlatexonly \\latexonly

  \addindex \\latexonly
  Starts a block of text that will be verbatim included in the
  generated \f$\mbox{\LaTeX}\f$ documentation only. The block ends with a
  endlatexonly command.

  This command can be used to include \f$\mbox{\LaTeX}\f$ code that is too 
  complex for doxygen (i.e. images, formulas, special characters). You can 
  use the \\htmlonly and \\endhtmlonly pair to provide a proper HTML 
  alternative.

  \b Note:
    environment variables (like \$(HOME) ) are resolved inside a 
    \f$\mbox{\LaTeX}\f$-only block.

  \sa section \ref cmdlatexonly "\\latexonly" 
  and section \ref cmdhtmlonly "\\htmlonly".

<hr>
\section cmdmanonly \\manonly

  \addindex \\manonly
  Starts a block of text that will be verbatim included in the
  generated MAN documentation only. The block ends with a
  endmanonly command.

  This command can be used to include groff code directly into
  MAN pages. You can use the \\htmlonly and \\latexonly and 
  \\endhtmlonly and \\endlatexonly pairs to provide proper 
  HTML and \f$\mbox{\LaTeX}\f$ alternatives.

  \sa section \ref cmdhtmlonly "\\htmlonly" and section 
              \ref cmdlatexonly "\\latexonly".

<hr>
\section cmdli \\li { item-description }
  
  \addindex \\li
  This command has one argument that continues until the first
  blank line or until another \\li is encountered.
  The command can be used to generate a simple, not nested list of
  arguments. 
  Each argument should start with a \\li command.
  
  \par Example:
  Typing:
  \verbatim
  \li \c AlignLeft left alignment.
  \li \c AlignCenter center alignment.
  \li \c AlignRight right alignment
  
  No other types of alignment are supported.
  \endverbatim
  will result in the following text:<br><br>
  <ul>
  <li> \c AlignLeft left alignment.
  <li> \c AlignCenter center alignment.
  <li> \c AlignRight right alignment
  </ul><br>
  No other types of alignment are supported.

  \par Note:
  For nested lists, HTML commands should be used.

  Equivalent to \ref cmdarg "\\arg"

<hr>
\section cmdn \\n 
  
  \addindex \\n
  Forces a new line. Equivalent to \<br\> and inspired by
  the printf function.

<hr>
\section cmdp \\p <word>
 
  \addindex \\p
  Displays the parameter \<word\> using a typewriter font.
  You can use this command to refer to member function parameters in 
  the running text.

  \par Example:
  \verbatim
  ... the \p x and \p y coordinates are used to ...
  \endverbatim 
  This will result in the following text:<br><br>
  ... the \p x and \p y coordinates are used to ...

  Equivalent to \ref cmdc "\\c"
 
<hr>
\section cmdverbatim \\verbatim

  \addindex \\verbatim
  Starts a block of text that will be verbatim included in both the
  HTML and the 
  \f$\mbox{\LaTeX}\f$ documentation. The block should end with a 
  \\endverbatim block. All commands are disabled in a verbatim block.

  \warning Make sure you include a \\endverbatim command for each 
  \\verbatim command or the parser will get confused!

  \sa section \ref cmdcode "\\code", and section \ref cmdverbinclude "\\verbinclude".

<hr>
\section cmdxmlonly \\xmlonly

  \addindex \\xmlonly
  Starts a block of text that will be verbatim included in the
  generated XML output only. The block ends with a
  endxmlonly command.

  This command can be used to include custom XML tags. 

  \sa section \ref cmdhtmlonly "\\htmlonly" and section 
              \ref cmdlatexonly "\\latexonly".

<hr>
\section cmdbackslash \\\\

  \addindex \\\\
  This command writes a backslash character (\\) to the HTML and 
  \f$\mbox{\LaTeX}\f$ output. The backslash has to be escaped in some 
  cases because doxygen uses it to detect commands.

<hr>
\section cmdat \\\@

  \addindex \\\@
  This command writes an at-sign (\@) to the HTML and 
  \f$\mbox{\LaTeX}\f$ output. The at-sign has to be escaped in some cases 
  because doxygen uses it to detect JavaDoc commands.

<hr>
\section cmdtilde \\~[LanguageId]
  \addindex \\~
  This command enables/disables a language specific filter. This can be
  used to put documentation for different language into one comment block
  and use the \c OUTPUT_LANGUAGE tag to filter out only a specific language.
  Use \\~language_id to enable output for a specific language only and
  \\~ to enable output for all languages (this is also the default mode).

  Example:
\verbatim
/*! \~english This is english \~dutch Dit is Nederlands \~german Dieses ist
    deutsch. \~ output for all languages.
 */
\endverbatim
   

<hr>
\section cmdamp \\\&

  \addindex \\\&
  This command writes the \& character to output. 
  This character has to be escaped because it has a special meaning in HTML.

<hr>
\section cmddollar \\\$

  \addindex \\\$
  This command writes the \$ character to the output. 
  This character has to be escaped in some cases, because it is used to expand 
  environment variables.

<hr>
\section cmdhash \\\#

  \addindex \\\#
  This command writes the \# character to the output. This 
  character has to be escaped in some cases, because it is used to refer
  to documented entities. 

<hr>
\section cmdlt \\\<

  \addindex \\\<
  This command writes the \< character to the output. 
  This character has to be escaped because it has a special meaning in HTML.

<hr>
\section cmdgt \\\>

  \addindex \\\>
  This command writes the \> character to the output. This 
  character has to be escaped because it has a special meaning in HTML.

\section cmdperc \\\%

  \addindex \\\%
  This command writes the \% character to the output. This 
  character has to be escaped in some cases, because it is used to 
  prevent auto-linking to word that is also a documented class or struct. 

<hr>
\section cmd_php_only PHP only commands
For PHP files there are a number of additional commands, that can be
used inside classes to make members public, private, or protected even
though the language itself doesn't support this notion.

To mark a single item use one of \\private, \\protected, \\public.
For starting a section with a certain protection level use one of:
\\privatesection, \\protectedsection, \\publicsection.
The latter commands are similar to 
"private:", "protected:", and "public:" in C++.
