/*! \page config Configuration

\tableofcontents
\section config_format Format

A configuration file is a free-form ASCII text file with a structure
that is similar to that of a \c Makefile, with the default name \c Doxyfile. It is
parsed by \c doxygen. The file may contain tabs and newlines for
formatting purposes. The statements in the file are case-sensitive.
Comments may be placed anywhere within the file (except within quotes).
Comments beginning with two hash characters (\c \#\#) are kept when updating
the configuration file and are placed in front of the TAG are in front of.
Comments beginning with two hash characters (\c \#\#) at the end of the
configuration file are also kept and placed at the end of the file.
Comments begin with the hash character (\c \#) and ends at the end of the line.

The file essentially consists of a list of assignment statements.
Each statement consists of a \c TAG_NAME written in capitals,
followed by the equal sign (<code>=</code>) and one or more values. If the same tag
is assigned more than once, the last assignment overwrites any earlier
assignment. For tags that take a list as their argument,
the <code>+=</code> operator can be used instead of <code>=</code> to append 
new values to the list. Values are sequences of non-blanks. If the value should 
contain one or more blanks it must be surrounded by quotes (<code>&quot;...&quot;</code>).
Multiple lines can be concatenated by inserting a backslash (\c \\)
as the last character of a line. Environment variables can be expanded 
using the pattern <code>\$(ENV_VARIABLE_NAME)</code>.

You can also include part of a configuration file from another configuration
file using a <code>\@INCLUDE</code> tag as follows:
\verbatim
@INCLUDE = config_file_name
\endverbatim 
The include file is searched in the current working directory. You can 
also specify a list of directories that should be searched before looking
in the current working directory. Do this by putting a <code>\@INCLUDE_PATH</code> tag 
with these paths before the <code>\@INCLUDE</code> tag, e.g.:
\verbatim
@INCLUDE_PATH = my_config_dir
\endverbatim

The configuration options can be divided into several categories.
Below is an alphabetical index of the tags that are recognized 
followed by the descriptions of the tags grouped by category.

\section config_project Project related options
\anchor cfg_doxyfile_encoding
<dl>

<dt>\c DOXYFILE_ENCODING <dd>
 \addindex DOXYFILE_ENCODING
 This tag specifies the encoding used for all characters in the config file that 
 follow. The default is UTF-8 which is also the encoding used for all text before
 the first occurrence of this tag. Doxygen uses \c libiconv (or the iconv built into
 \c libc) for the transcoding. See http://www.gnu.org/software/libiconv for the list of
 possible encodings.

\anchor cfg_project_name
<dt>\c PROJECT_NAME <dd>
 \addindex PROJECT_NAME
 The \c PROJECT_NAME tag is a single word (or a sequence of words
 surrounded by double-quotes) that should identify the project for which the 
 documentation is generated. This name is used in the title of most 
 generated pages and in a few other places.

\anchor cfg_project_number
<dt>\c PROJECT_NUMBER <dd>
 \addindex PROJECT_NUMBER
 The \c PROJECT_NUMBER tag can be used to enter a project or revision number.
 This could be handy for archiving the generated documentation or
 if some version control system is used.

\anchor cfg_project_brief
<dt>\c PROJECT_BRIEF <dd>
 Using the \c PROJECT_BRIEF tag one can provide an optional one line description 
 for a project that appears at the top of each page and should give viewer 
 a quick idea about the purpose of the project. Keep the description short. 

\anchor cfg_project_logo
<dt>\c PROJECT_LOGO <dd>
 With the \c PROJECT_LOGO tag one can specify an logo or icon that is 
 included in the documentation. The maximum height of the logo should not 
 exceed 55 pixels and the maximum width should not exceed 200 pixels. 
 Doxygen will copy the logo to the output directory.

\anchor cfg_output_directory
<dt>\c OUTPUT_DIRECTORY <dd> 
 \addindex OUTPUT_DIRECTORY
 The \c OUTPUT_DIRECTORY tag is used to specify the (relative or absolute) 
 path into which the generated documentation will be written. 
 If a relative path is entered, it will be relative to the location 
 where doxygen was started. If left blank the current directory will be used.

\anchor cfg_create_subdirs
<dt>\c CREATE_SUBDIRS <dd> 
 \addindex CREATE_SUBDIRS
 If the \c CREATE_SUBDIRS tag is set to \c YES, then doxygen will create
 4096 sub-directories (in 2 levels) under the output directory of each output 
 format and will distribute the generated files over these directories. 
 Enabling this option can be useful when feeding doxygen a huge amount of source
 files, where putting all generated files in the same directory would otherwise
 causes performance problems for the file system. 

\anchor cfg_output_language
<dt>\c OUTPUT_LANGUAGE <dd>
 \addindex OUTPUT_LANGUAGE
 The \c OUTPUT_LANGUAGE tag is used to specify the language in which all
 documentation generated by doxygen is written. Doxygen will use this
 information to generate all constant output in the proper language.
 The default language is English, other supported languages are:
 Afrikaans, Arabic, Brazilian, Catalan, Chinese, Croatian, Czech, Danish, Dutch, 
 Finnish, French, German, Greek, Hungarian, Italian, Japanese, Korean, 
 Latvian, Lithuanian, Norwegian, Persian, Polish, Portuguese, Romanian, Russian, 
 Serbian,  Serbian-Cyrillic, Slovak, Slovene, Spanish, Swedish, and Ukrainian.

\anchor cfg_brief_member_desc
<dt>\c BRIEF_MEMBER_DESC <dd>
 \addindex BRIEF_MEMBER_DESC
 If the \c BRIEF_MEMBER_DESC tag is set to \c YES (the default) doxygen will
 include brief member descriptions after the members that are listed in
 the file and class documentation (similar to \c Javadoc).
 Set to \c NO to disable this.

\anchor cfg_repeat_brief
<dt>\c REPEAT_BRIEF <dd>
 \addindex REPEAT_BRIEF
 If the \c REPEAT_BRIEF tag is set to \c YES (the default) doxygen will 
 prepend the brief description of a member or function before the detailed 
 description 

 \par Note: 
 If both \ref cfg_hide_undoc_members "HIDE_UNDOC_MEMBERS" and
 \ref cfg_brief_member_desc "BRIEF_MEMBER_DESC" are set to \c NO, the 
 brief descriptions will be completely suppressed.

\anchor cfg_abbreviate_brief
<dt>\c ABBREVIATE_BRIEF <dd>
 \addindex ABBREVIATE_BRIEF
 This tag implements a quasi-intelligent brief description abbreviator
 that is used to form the text in various listings. Each string
 in this list, if found as the leading text of the brief description, will be
 stripped from the text and the result, after processing the whole list, is used
 as the annotated text. Otherwise, the brief description is used as-is. If left
 blank, the following values are used ("$name" is automatically replaced with the
 name of the entity): "The $name class" "The $name widget" "The $name file"
 "is" "provides" "specifies" "contains" "represents" "a" "an" "the".

\anchor cfg_always_detailed_sec
<dt>\c ALWAYS_DETAILED_SEC <dd>
 \addindex ALWAYS_DETAILED_SEC
 If the \c ALWAYS_DETAILED_SEC and \ref cfg_repeat_brief "REPEAT_BRIEF" tags 
 are both set to \c YES then
 doxygen will generate a detailed section even if there is only a brief
 description.

\anchor cfg_inline_inherited_memb
<dt>\c INLINE_INHERITED_MEMB <dd>
\addindex INLINE_INHERITED_MEMB
 If the \c INLINE_INHERITED_MEMB tag is set to \c YES, doxygen will show all inherited
 members of a class in the documentation of that class as if those members were
 ordinary class members. Constructors, destructors and assignment operators of
 the base classes will not be shown.

\anchor cfg_full_path_names
<dt>\c FULL_PATH_NAMES <dd>
 \addindex FULL_PATH_NAMES
 If the \c FULL_PATH_NAMES tag is set to \c YES doxygen will prepend the full
 path before files name in the file list and in the header files. If set
 to \c NO the shortest path that makes the file name unique will be used

\anchor cfg_strip_from_path
<dt>\c STRIP_FROM_PATH <dd>
 \addindex STRIP_FROM_PATH
 If the \ref cfg_full_path_names "FULL_PATH_NAMES" tag is set to \c YES then the \c STRIP_FROM_PATH tag
 can be used to strip a user-defined part of the path. Stripping is
 only done if one of the specified strings matches the left-hand part of the 
 path. The tag can be used to show relative paths in the file list.
 If left blank the directory from which doxygen is run is used as the
 path to strip.

\anchor cfg_strip_from_inc_path
<dt>\c STRIP_FROM_INC_PATH <dd>
 \addindex STRIP_FROM_INC_PATH
 The \c STRIP_FROM_INC_PATH tag can be used to strip a user-defined part of 
 the path mentioned in the documentation of a class, which tells
 the reader which header file to include in order to use a class. 
 If left blank only the name of the header file containing the class
 definition is used. Otherwise one should specify the include paths that 
 are normally passed to the compiler using the `-I` flag.

\anchor cfg_short_names
<dt>\c SHORT_NAMES <dd>
 \addindex SHORT_NAMES
 If the \c SHORT_NAMES tag is set to \c YES, doxygen will generate much shorter
 (but less readable) file names. This can be useful is your file systems
 doesn't support long names like on DOS, Mac, or CD-ROM.

\anchor cfg_javadoc_autobrief
<dt>\c JAVADOC_AUTOBRIEF <dd>
 \addindex JAVADOC_AUTOBRIEF
  If the \c JAVADOC_AUTOBRIEF is set to \c YES then doxygen
  will interpret the first line (until the first dot) of a Javadoc-style
  comment as the brief description. If set to \c NO (the default), the 
  Javadoc-style will behave just like regular Qt-style comments
  (thus requiring an explicit \ref cmdbrief "\@brief" command for a brief description.)

\anchor cfg_qt_autobrief
<dt>\c QT_AUTOBRIEF <dd>
 \addindex QT_AUTOBRIEF
  If the \c QT_AUTOBRIEF is set to \c YES then doxygen
  will interpret the first line (until the first dot) of a Qt-style
  comment as the brief description. If set to \c NO (the default), the
  Qt-style will behave just like regular Qt-style comments (thus
  requiring an explicit \ref cmdbrief "\\brief" command for a brief description.)

\anchor cfg_markdown_support
<dt>\c MARKDOWN_SUPPORT <dd>
 \addindex MARKDOWN_SUPPORT
 If \c MARKDOWN_SUPPORT is enabled (the default) then doxygen pre-processes all 
 comments according to the Markdown format, which allows for more readable 
 documentation. See http://daringfireball.net/projects/markdown/ for details. 
 The output of markdown processing is further processed by doxygen, so you 
 can mix doxygen, HTML, and XML commands with Markdown formatting. 
 Disable only in case of backward compatibilities issues. 

\anchor cfg_autolink_support
<dt>\c AUTOLINK_SUPPORT <dd>
 \addindex AUTOLINK_SUPPORT
 When enabled doxygen tries to link words that correspond to documented classes, 
 or namespaces to their corresponding documentation. Such a link can be 
 prevented in individual cases by by putting a \c % sign in front of the word or 
 globally by setting \c AUTOLINK_SUPPORT to \c NO.

\anchor cfg_builtin_stl_support
<dt>\c BUILTIN_STL_SUPPORT <dd>
 \addindex BUILTIN_STL_SUPPORT
 If you use STL classes (i.e. `std::string`, `std::vector`, etc.) but do not want to
 include (a tag file for) the STL sources as input, then you should
 set this tag to \c YES in order to let doxygen match functions declarations and
 definitions whose arguments contain STL classes (e.g. `func(std::string`); versus
 `func(std::string) {}`). This also make the inheritance and collaboration
 diagrams that involve STL classes more complete and accurate.

\anchor cfg_cpp_cli_support
<dt>\c CPP_CLI_SUPPORT <dd>
 \addindex CPP_CLI_SUPPORT
 If you use Microsoft's C++/CLI language, you should set this option to \c YES to
 enable parsing support.

\anchor cfg_sip_support
<dt>\c SIP_SUPPORT <dd>
 \addindex OPTIMIZE_OUTPUT_SIP
 Set the \c SIP_SUPPORT tag to \c YES if your project consists 
 of <a href="http://www.riverbankcomputing.co.uk/software/sip/intro">sip</a> sources only. 
 Doxygen will parse them like normal C++ but will assume all classes use public 
 instead of private inheritance when no explicit protection keyword is present. 

\anchor cfg_idl_property_support
<dt>\c IDL_PROPERTY_SUPPORT <dd>
 \addindex IDL_PROPERTY_SUPPORT
 For Microsoft's IDL there are \c propget and \c propput attributes to indicate getter
 and setter methods for a property. Setting this option to \c YES (the default)
 will make doxygen to replace the get and set methods by a property in the
 documentation. This will only work if the methods are indeed getting or 
 setting a simple type. If this is not the case, or you want to show the 
 methods anyway, you should set this option to \c NO.

\anchor cfg_distribute_group_doc
<dt>\c DISTRIBUTE_GROUP_DOC <dd>
 \addindex DISTRIBUTE_GROUP_DOC
 If member grouping is used in the documentation and the \c DISTRIBUTE_GROUP_DOC
 tag is set to \c YES, then doxygen will reuse the documentation of the first
 member in the group (if any) for the other members of the group. By default
 all members of a group must be documented explicitly.

\anchor cfg_multiline_cpp_is_brief
<dt>\c MULTILINE_CPP_IS_BRIEF <dd>
 \addindex MULTILINE_CPP_IS_BRIEF
  The \c MULTILINE_CPP_IS_BRIEF tag can be set to \c YES to make doxygen
  treat a multi-line C++ special comment block (i.e. a block of \c //! or \c ///
  comments) as a brief description. This used to be the default behavior.
  The new default is to treat a multi-line C++ comment block as a detailed
  description. Set this tag to \c YES if you prefer the old behavior instead.
  Note that setting this tag to \c YES also means that rational rose comments
  are not recognized any more.

<!--
\anchor cfg_details_at_top
<dt>\c DETAILS_AT_TOP <dd>
 \addindex DETAILS_AT_TOP
  If the \c DETAILS_AT_TOP tag is set to \c YES then doxygen
  will output the detailed description near the top, like \c Javadoc.
  If set to \c NO, the detailed description appears after the member
  documentation.
-->

\anchor cfg_inherit_docs
<dt>\c INHERIT_DOCS <dd>
 \addindex INHERIT_DOCS
 If the \c INHERIT_DOCS tag is set to \c YES (the default) then an undocumented
 member inherits the documentation from any documented member that it
 re-implements.

\anchor cfg_separate_member_pages
<dt>\c SEPARATE_MEMBER_PAGES <dd>
 \addindex SEPARATE_MEMBER_PAGES
 If the \c SEPARATE_MEMBER_PAGES tag is set to \c YES, then doxygen will produce
 a new page for each member. If set to \c NO, the documentation of a member will
 be part of the file/class/namespace that contains it.

\anchor cfg_tab_size
<dt>\c TAB_SIZE <dd>
 \addindex TAB_SIZE
 the \c TAB_SIZE tag can be used to set the number of spaces in a tab.
 Doxygen uses this value to replace tabs by spaces in code fragments.

\anchor cfg_aliases
<dt>\c ALIASES <dd>
 \addindex ALIASES
 This tag can be used to specify a number of aliases that acts 
 as commands in the documentation. An alias has the form 
\verbatim
 name=value
\endverbatim
 For example adding 
\verbatim
 "sideeffect=\par Side Effects:\n" 
\endverbatim
 will allow you to
 put the command \c \\sideeffect (or \c \@sideeffect) in the documentation, which 
 will result in a user-defined paragraph with heading "Side Effects:".
 You can put \ref cmdn "\\n"'s in the value part of an alias to insert newlines.

\anchor cfg_tcl_subst
<dt>\c TCL_SUBST <dd>
 \addindex TCL_SUBST
 This tag can be used to specify a number of word-keyword mappings (TCL only). 
 A mapping has the form <code>"name=value"</code>. For example adding 
 <code>"class=itcl::class"</code> will allow you to use the command class in the 
 <code>itcl::class</code> meaning.

\anchor cfg_optimize_output_for_c
<dt>\c OPTIMIZE_OUTPUT_FOR_C <dd>
 \addindex OPTIMIZE_OUTPUT_FOR_C
 Set the \c OPTIMIZE_OUTPUT_FOR_C tag to \c YES if your project consists 
 of C sources only. Doxygen will then generate output that is more tailored 
 for C. For instance, some of the names that are used will be different. 
 The list of all members will be omitted, etc. 

\anchor cfg_optimize_output_java
<dt>\c OPTIMIZE_OUTPUT_JAVA <dd>
 \addindex OPTIMIZE_OUTPUT_JAVA
 Set the \c OPTIMIZE_OUTPUT_JAVA tag to \c YES if your project consists of Java or
 Python sources only. Doxygen will then generate output that is more tailored 
 for that language. For instance, namespaces will be presented as packages, 
 qualified scopes will look different, etc. 

\anchor cfg_optimize_for_fortran
<dt>\c OPTIMIZE_FOR_FORTRAN <dd>
 \addindex OPTIMIZE_FOR_FORTRAN
 Set the \c OPTIMIZE_FOR_FORTRAN tag to \c YES if your project consists of Fortran 
 sources. Doxygen will then generate output that is tailored for Fortran.

\anchor cfg_optimize_output_vhdl
<dt>\c OPTIMIZE_OUTPUT_VHDL <dd>
 \addindex OPTIMIZE_OUTPUT_VHDL
 Set the \c OPTIMIZE_OUTPUT_VHDL tag to \c YES if your project consists of VHDL 
 sources. Doxygen will then generate output that is tailored for VHDL.

\anchor cfg_extension_mapping
<dt>\c EXTENSION_MAPPING <dd>
 \addindex EXTENSION_MAPPING
 Doxygen selects the parser to use depending on the extension of the files it parses.
 With this tag you can assign which parser to use for a given extension.
 Doxygen has a built-in mapping, but you can override or extend it using this tag.
 The format is ext=language, where ext is a file extension, and language is one of
 the parsers supported by doxygen: IDL, Java, Javascript, C#, C, C++, D, PHP,
 Objective-C, Python, Fortran, VHDL. 

 For instance to make doxygen treat
 <code>.inc</code> files as Fortran files (default is PHP), and <code>.f</code> files as C (default is Fortran),
 use: `inc=Fortran f=C`.

 For files without extension you can use `no_extension` as a placeholder.

\anchor cfg_subgrouping
<dt>\c SUBGROUPING <dd>
 \addindex SUBGROUPING
 Set the \c SUBGROUPING tag to \c YES (the default) to allow class member groups of
 the same type (for instance a group of public functions) to be put as a
 subgroup of that type (e.g. under the Public Functions section). Set it to
 \c NO to prevent subgrouping. Alternatively, this can be done per class using
 the \ref cmdnosubgrouping "\\nosubgrouping" command. 

\anchor cfg_inline_grouped_classes
<dt>\c INLINE_GROUPED_CLASSES <dd>
 \addindex INLINE_GROUPED_CLASSES
When the \c INLINE_GROUPED_CLASSES tag is set to \c YES, classes, structs and 
unions are shown inside the group in which they are included 
(e.g. using \ref cmdingroup "\\ingroup") instead of on a separate page (for HTML and Man pages) 
or section (for \f$\mbox{\LaTeX}\f$ and RTF). Note that this feature does not work in
combination with \ref cfg_separate_member_pages "SEPARATE_MEMBER_PAGES".

\anchor cfg_inline_simple_structs
<dt>\c INLINE_SIMPLE_STRUCTS <dd>
 \addindex INLINE_SIMPLE_STRUCTS
When the \c INLINE_SIMPLE_STRUCTS tag is set to \c YES, structs, classes, and 
unions with only public data fields or simple typedef fields will be shown 
inline in the documentation of the scope in which they are defined (i.e. file, 
namespace, or group documentation), provided this scope is documented. If set 
to \c NO (the default), structs, classes, and unions are shown on a separate 
page (for HTML and Man pages) or section (for \f$\mbox{\LaTeX}\f$ and RTF).

\anchor cfg_typedef_hides_struct 
<dt>\c TYPEDEF_HIDES_STRUCT <dd>
 \addindex TYPEDEF_HIDES_STRUCT
 When \c TYPEDEF_HIDES_STRUCT is enabled, a typedef of a struct, union, or enum
 is documented as struct, union, or enum with the name of the typedef. So 
 <code>typedef struct TypeS {} TypeT</code>, will appear in the documentation as a struct 
 with name \c TypeT. When disabled the typedef will appear as a member of a file, 
 namespace, or class. And the struct will be named \c TypeS. This can typically 
 be useful for C code in case the coding convention dictates that all compound 
 types are typedef'ed and only the typedef is referenced, never the tag name.

\anchor cfg_lookup_cache_size
<dt>\c LOOKUP_CACHE_SIZE <dd>
 \addindex LOOKUP_CACHE_SIZE
 The size of the symbol lookup cache can be 
 set using \c LOOKUP_CACHE_SIZE. This cache is used to resolve symbols given 
 their name and scope. Since this can be an expensive process and often the 
 same symbol appears multiple times in the code, doxygen keeps a cache of 
 pre-resolved symbols. If the cache is too small doxygen will become slower. 
 If the cache is too large, memory is wasted. The cache size is given by this 
 formula: \f$2^{(16+\mbox{LOOKUP\_CACHE\_SIZE})}\f$. The valid range is 0..9, the default is 0, 
 corresponding to a cache size of \f$2^{16} = 65536\f$ symbols. 
 At the end of a run doxygen will report the cache usage and suggest the
 optimal cache size from a speed point of view.

 have any effect for Java sources.

\anchor cfg_extract_anon_nspaces
<dt>\c EXTRACT_ANON_NSPACES <dd>
 \addindex EXTRACT_ANON_NSPACES
 If this flag is set to \c YES, the members of anonymous namespaces will be extracted
 and appear in the documentation as a namespace called 'anonymous_namespace{file}',
 where file will be replaced with the base name of the file that contains the anonymous
 namespace. By default anonymous namespace are hidden.

\anchor cfg_extract_local_methods
<dt>\c EXTRACT_LOCAL_METHODS <dd>
 \addindex EXTRACT_LOCAL_METHODS
 This flag is only useful for Objective-C code. When set to \c YES local 
 methods, which are defined in the implementation section but not in
 the interface are included in the documentation.
 If set to \c NO (the default) only methods in the interface are included.

\anchor cfg_hide_undoc_members
<dt>\c HIDE_UNDOC_MEMBERS <dd>
 \addindex HIDE_UNDOC_MEMBERS
 If the \c HIDE_UNDOC_MEMBERS tag is set to \c YES, doxygen will hide all
 undocumented members inside documented classes or files. 
 If set to \c NO (the default) these members will be included in the
 various overviews, but no documentation section is generated.
 This option has no effect if \ref cfg_extract_all "EXTRACT_ALL" is enabled.

\anchor cfg_hide_undoc_classes
<dt>\c HIDE_UNDOC_CLASSES <dd>
 \addindex HIDE_UNDOC_CLASSES
 If the \c HIDE_UNDOC_CLASSESS tag is set to \c YES, doxygen will hide all

<dt>\c HIDE_IN_BODY_DOCS <dd>
 \addindex HIDE_IN_BODY_DOCS
If the \c HIDE_IN_BODY_DOCS tag is set to \c YES, doxygen will hide any 
documentation blocks found inside the body of a function.
If set to \c NO (the default) these blocks will be appended to the 
function's detailed documentation block.
 
\anchor cfg_internal_docs
<dt>\c INTERNAL_DOCS <dd>
 \addindex INTERNAL_DOCS
 The \c INTERNAL_DOCS tag determines if documentation
 that is typed after a \ref cmdinternal "\\internal" command is included. If the tag is set
 to \c NO (the default) then the documentation will be excluded.
 Set it to \c YES to include the internal documentation.

\anchor cfg_case_sense_names
<dt>\c CASE_SENSE_NAMES <dd>
 \addindex CASE_SENSE_NAMES
 If the \c CASE_SENSE_NAMES tag is set to \c NO then doxygen
 will only generate file names in lower-case letters. If set to
 \c YES upper-case letters are also allowed. This is useful if you have
 classes or files whose names only differ in case and if your file system
 supports case sensitive file names. Windows users are advised to set this
 option to \c NO.

\anchor cfg_hide_scope_names
<dt>\c HIDE_SCOPE_NAMES <dd>
 \addindex HIDE_SCOPE_NAMES
 If the \c HIDE_SCOPE_NAMES tag is set to \c NO (the default) then doxygen

 will put a list of the files that are included by a file in the documentation 
 of that file.

\anchor cfg_force_local_includes
<dt>\c FORCE_LOCAL_INCLUDES <dd>
 \addindex FORCE_LOCAL_INCLUDES
 If the \c FORCE_LOCAL_INCLUDES tag is set to \c YES then doxygen 
 will list include files with double quotes in the documentation 
 rather than with sharp brackets.

\anchor cfg_inline_info
<dt>\c INLINE_INFO <dd>
 \addindex INLINE_INFO 
 If the \c INLINE_INFO tag is set to \c YES (the default) then a tag [inline]
 is inserted in the documentation for inline members.

\anchor cfg_sort_member_docs
<dt>\c SORT_MEMBER_DOCS <dd>
 \addindex SORT_MEMBER_DOCS
 If the \c SORT_MEMBER_DOCS tag is set to \c YES (the default) then doxygen
 will sort the (detailed) documentation of file and class members
 alphabetically by member name. If set to \c NO the members will appear in
 declaration order.

\anchor cfg_sort_brief_docs
<dt>\c SORT_BRIEF_DOCS <dd>
 \addindex SORT_BRIEF_DOCS
 If the \c SORT_BRIEF_DOCS tag is set to \c YES then doxygen will sort the
 brief descriptions of file, namespace and class members alphabetically
 by member name. If set to \c NO (the default) the members will appear in
 declaration order.


\anchor cfg_sort_group_names
<dt>\c SORT_GROUP_NAMES <dd>
 \addindex SORT_GROUP_NAMES
 If the \c SORT_GROUP_NAMES tag is set to \c YES then doxygen will sort the 
 hierarchy of group names into alphabetical order. If set to \c NO (the default)
 the group names will appear in their defined order. 

\anchor cfg_sort_by_scope_name
<dt>\c SORT_BY_SCOPE_NAME <dd>
 \addindex SORT_BY_SCOPE_NAME
 If the \c SORT_BY_SCOPE_NAME tag is set to \c YES, the class list will be
 sorted by fully-qualified names, including namespaces. If set to
 \c NO (the default), the class list will be sorted only by class name,
 not including the namespace part.
 @note This option is not very useful if \ref cfg_hide_scope_names "HIDE_SCOPE_NAMES" is set to \c YES.
 @note This option applies only to the class list, not to the 
       alphabetical list.

\anchor cfg_sort_members_constructors_first
<dt>\c SORT_MEMBERS_CTORS_1ST <dd>
 \addindex SORT_MEMBERS_CTORS_1ST
 If the \c SORT_MEMBERS_CTORS_1ST tag is set to \c YES then doxygen
 will sort the (brief and detailed) documentation of class members so that
 constructors and destructors are listed first. If set to \c NO (the default)
 the constructors will appear in the respective orders defined by
 \ref cfg_sort_brief_docs "SORT_BRIEF_DOCS" and \ref cfg_sort_member_docs "SORT_MEMBER_DOCS".

       sorting detailed member documentation.

\anchor cfg_generate_deprecatedlist
<dt>\c GENERATE_DEPRECATEDLIST <dd>
 \addindex GENERATE_DEPRECATEDLIST
 The \c GENERATE_DEPRECATEDLIST tag can be used to enable (\c YES) or
 disable (\c NO) the deprecated list. This list is created by 
 putting \ref cmddeprecated "\\deprecated"
 commands in the documentation.

\anchor cfg_strict_proto_matching
<dt>\c STRICT_PROTO_MATCHING <dd>
 \addindex STRICT_PROTO_MATCHING
 If the \c STRICT_PROTO_MATCHING option is enabled and doxygen fails to
 do proper type resolution of all parameters of a function it will reject a  
 match between the prototype and the implementation of a member function even
 if there is only one candidate or it is obvious which candidate to choose
 by doing a simple string match. By disabling \c STRICT_PROTO_MATCHING doxygen 
 will still accept a match between prototype and implementation in such cases.

\anchor cfg_generate_todolist
<dt>\c GENERATE_TODOLIST <dd>
 \addindex GENERATE_TODOLIST
 The \c GENERATE_TODOLIST tag can be used to enable (\c YES) or

 \ref cmdendif "\\endif" and \ref cmdcond "\\cond" \<section-label\> ...
 \ref cmdendcond "\\endcond" blocks.

\anchor cfg_max_initializer_lines
<dt>\c MAX_INITIALIZER_LINES <dd>
 \addindex MAX_INITIALIZER_LINES
 The \c MAX_INITIALIZER_LINES tag determines the maximum number of lines
 that the initial value of a variable or define can be. If the initializer
 consists of more lines than specified here it will be hidden. Use a value
 of 0 to hide initializers completely. The appearance of the value of
 individual variables and defines can be controlled using \ref cmdshowinitializer "\\showinitializer"
 or \ref cmdhideinitializer "\\hideinitializer" command in the documentation.

\anchor cfg_show_used_files
<dt>\c SHOW_USED_FILES <dd>
 \addindex SHOW_USED_FILES
 Set the \c SHOW_USED_FILES tag to \c NO to disable the list of files generated
 at the bottom of the documentation of classes and structs. If set to \c YES the
 list will mention the files that were used to generate the documentation.

\anchor cfg_show_files
<dt>\c SHOW_FILES <dd>
 \addindex SHOW_FILES
 Set the \c SHOW_FILES tag to \c NO to disable the generation of the Files page.
 This will remove the Files entry from the Quick Index and from the

 and from the Folder Tree View (if specified). The default is \c YES.

\anchor cfg_file_version_filter
<dt>\c FILE_VERSION_FILTER <dd>
 \addindex FILE_VERSION_FILTER
 The \c FILE_VERSION_FILTER tag can be used to specify a program or script that
 doxygen should invoke to get the current version for each file (typically from the
 version control system). Doxygen will invoke the program by executing (via
 <code>popen()</code>) the command <code>command input-file</code>, where \c command is 
 the value of the \c FILE_VERSION_FILTER tag, and \c input-file is the name 
 of an input file provided by doxygen. 
 Whatever the program writes to standard output is used as the file version. 

Example of using a shell script as a filter for Unix:
\verbatim
 FILE_VERSION_FILTER = "/bin/sh versionfilter.sh"
\endverbatim

Example shell script for CVS:
\verbatim
#!/bin/sh
cvs status $1 | sed -n 's/^[ \]*Working revision:[ \t]*\([0-9][0-9\.]*\).*/\1/p'
\endverbatim 
 
Example shell script for Subversion:
\verbatim
#!/bin/sh
svn stat -v $1 | sed -n 's/^[ A-Z?\*|!]\{1,15\}/r/;s/ \{1,15\}/\/r/;s/ .*//p'
\endverbatim

Example filter for ClearCase:
\verbatim
FILE_VERSION_INFO = "cleartool desc -fmt \%Vn"
\endverbatim

\anchor cfg_layout_file
<dt>\c LAYOUT_FILE <dd>
 The \c LAYOUT_FILE tag can be used to specify a layout file which will be parsed by
 doxygen. The layout file controls the global structure of the generated output files
 in an output format independent way. To create the layout file that represents
 doxygen's defaults, run doxygen with the -l option. You can optionally specify a
 file name after the option, if omitted \c DoxygenLayout.xml will be used as the name
 of the layout file. Note that if you run doxygen from a directory containing 
 a file called \c DoxygenLayout.xml, doxygen will parse it automatically even if 
 the \c LAYOUT_FILE tag is left empty.

\anchor cfg_cite_bib_files
<dt>\c CITE_BIB_FILES <dd>
 \addindex CITE_BIB_FILES
 The \c CITE_BIB_FILES tag can be used to specify one or more bib files 
 containing the reference definitions. This must be a list of <code>.bib</code> files. The 
 <code>.bib</code> extension is automatically appended if omitted. This requires the 
 \c bibtex tool to be installed. See also http://en.wikipedia.org/wiki/BibTeX 
 for more info. For \f$\mbox{\LaTeX}\f$ the style of the bibliography can be controlled 
 using \ref cfg_latex_bib_style "LATEX_BIB_STYLE". See 
 also \ref cmdcite "\\cite" for info how to create references.

 where \c YES implies that the messages are off.
 If left blank \c NO is used.

\anchor cfg_warnings
<dt>\c WARNINGS <dd>
 \addindex WARNINGS
 The \c WARNINGS tag can be used to turn on/off the warning messages that are
 generated to standard error by doxygen. Possible values are \c YES and \c NO, 
 where \c YES implies that the warnings are on. If left blank \c NO is used.

 \b Tip: Turn warnings on while writing the documentation.

\anchor cfg_warn_if_undocumented
<dt>\c WARN_IF_UNDOCUMENTED <dd>
 \addindex WARN_IF_UNDOCUMENTED
 If \c WARN_IF_UNDOCUMENTED is set to \c YES, then doxygen will generate warnings
 for undocumented members. If \ref cfg_extract_all "EXTRACT_ALL" is set to \c YES then this flag will
 automatically be disabled.

\anchor cfg_warn_if_doc_error
<dt>\c WARN_IF_DOC_ERROR <dd>
 \addindex WARN_IF_DOC_ERROR
 If \c WARN_IF_DOC_ERROR is set to \c YES, doxygen will generate warnings for
 potential errors in the documentation, such as not documenting some
 parameters in a documented function, or documenting parameters that
 don't exist or using markup commands wrongly. 

\anchor cfg_warn_no_paramdoc
<dt>\c WARN_NO_PARAMDOC <dd>
 \addindex WARN_NO_PARAMDOC
 This \c WARN_NO_PARAMDOC option can be enabled to get warnings for 
 functions that are documented, but have no documentation for their parameters
 or return value. If set to \c NO (the default) doxygen will only warn about
 wrong or incomplete parameter documentation, but not about the absence of
 documentation.

\anchor cfg_warn_format
<dt>\c WARN_FORMAT <dd>
 \addindex WARN_FORMAT
 The \c WARN_FORMAT tag determines the format of the warning messages that
 doxygen can produce. The string should contain the <code>\$file</code>, 
 <code>\$line</code>, and <code>\$text</code> 
 tags, which will be replaced by the file and line number from which the
 warning originated and the warning text.

\anchor cfg_warn_logfile
<dt>\c WARN_LOGFILE <dd>
 \addindex WARN_LOGFILE
 The \c WARN_LOGFILE tag can be used to specify a file to which warning
 and error messages should be written. If left blank the output is written 
 to \c stderr.

</dl>

\section config_input Input related options
\anchor cfg_input
<dl>

<dt>\c INPUT <dd>
 \addindex INPUT
 The \c INPUT tag is used to specify the files and/or directories that contain 
 documented source files. You may enter file names like 
 \c myfile.cpp or directories like \c /usr/src/myproject. 
 Separate the files or directories with spaces.<br>

 \note If this tag is empty the current directory is searched.

\anchor cfg_input_encoding
<dt>\c INPUT_ENCODING <dd>
 \addindex INPUT_ENCODING
 This tag can be used to specify the character encoding of the source files that 
 doxygen parses. Internally doxygen uses the UTF-8 encoding, which is also the default 
 input encoding. Doxygen uses `libiconv` (or the `iconv` built into `libc`) for the transcoding. 
 See <a href="http://www.gnu.org/software/libiconv">the libiconv documentation</a> for 
 the list of possible encodings.

\anchor cfg_file_patterns
<dt>\c FILE_PATTERNS <dd>
 \addindex FILE_PATTERNS
 If the value of the \ref cfg_input "INPUT" tag contains directories, you can use the 
 \c FILE_PATTERNS tag to specify one or more wildcard patterns 
 (like `*.cpp` and `*.h`) to filter out the source-files 
 in the directories. If left blank the following patterns are tested:
 <code>
 *.c *.cc *.cxx *.cpp *.c++ *.d *.java *.ii *.ixx *.ipp *.i++ *.inl *.h *.hh 
 *.hxx *.hpp *.h++ *.idl *.odl *.cs *.php *.php3 *.inc *.m *.markdown *.md 
 *.mm *.dox *.py *.f90 *.f *.vhd *.vhdl
 </code>

\anchor cfg_recursive
<dt>\c RECURSIVE <dd>
 \addindex RECURSIVE
 The \c RECURSIVE tag can be used to specify whether or not subdirectories
 should be searched for input files as well. Possible values are \c YES 
 and \c NO.  If left blank \c NO is used.

\anchor cfg_exclude
<dt>\c EXCLUDE <dd>
 \addindex EXCLUDE
 The \c EXCLUDE tag can be used to specify files and/or directories that should be
 excluded from the \ref cfg_input "INPUT" source files. This way you can easily exclude a
 subdirectory from a directory tree whose root is specified with the \ref cfg_input "INPUT" tag.
 Note that relative paths are relative to the directory from which doxygen is run.

\anchor cfg_exclude_symlinks
<dt>\c EXCLUDE_SYMLINKS <dd>
 \addindex EXCLUDE_SYMLINKS
 The \c EXCLUDE_SYMLINKS tag can be used to select whether or not files or directories 
 that are symbolic links (a Unix file system feature) are excluded from the input.

\anchor cfg_exclude_patterns
<dt>\c EXCLUDE_PATTERNS <dd>
 \addindex EXCLUDE_PATTERNS
 If the value of the \ref cfg_input "INPUT" tag contains directories, you can use the
 \c EXCLUDE_PATTERNS tag to specify one or more wildcard patterns to exclude
 certain files from those directories.

\anchor cfg_exclude_symbols
<dt>\c EXCLUDE_SYMBOLS <dd>
The \c EXCLUDE_SYMBOLS tag can be used to specify one or more symbol names 
(namespaces, classes, functions, etc.) that should be excluded from the 
output. The symbol name can be a fully qualified name, a word, or if the 
wildcard `*` is used, a substring. Examples: `ANamespace`, `AClass`, 
`AClass::ANamespace`, `ANamespace::*Test` 

 Note that the wildcards are matched against the file with absolute path, 
 so to exclude all test directories use the pattern 
 `*``/test/``*`

\anchor cfg_example_path
<dt>\c EXAMPLE_PATH <dd>
 \addindex EXAMPLE_PATH
 The \c EXAMPLE_PATH tag can be used to specify one or more files or
 directories that contain example code fragments that are included (see
 the \ref cmdinclude "\\include" command).

\anchor cfg_example_recursive
<dt>\c EXAMPLE_RECURSIVE <dd>
 \addindex EXAMPLE_RECURSIVE
 If the \c EXAMPLE_RECURSIVE tag is set to \c YES then subdirectories will be
 searched for input files to be used with the \ref cmdinclude "\\include" or
 \ref cmddontinclude "\\dontinclude" 
 commands irrespective of the value of the \ref cfg_recursive "RECURSIVE" tag. 
 Possible values are \c YES and \c NO. If left blank \c NO is used. 

\anchor cfg_example_patterns
<dt>\c EXAMPLE_PATTERNS <dd>
 \addindex EXAMPLE_PATTERNS
 If the value of the \ref cfg_example_path "EXAMPLE_PATH" tag contains directories, 
 you can use the
 \c EXAMPLE_PATTERNS tag to specify one or more wildcard pattern (like `*.cpp`
 and `*.h`) to filter out the source-files in the directories. If left
 blank all files are included.

\anchor cfg_image_path
<dt>\c IMAGE_PATH <dd>
 \addindex IMAGE_PATH
 The \c IMAGE_PATH tag can be used to specify one or more files or
 directories that contain images that are to be included in the 
 documentation (see the \ref cmdimage "\\image" command).

\anchor cfg_input_filter
<dt>\c INPUT_FILTER <dd>
 \addindex INPUT_FILTER
 The \c INPUT_FILTER tag can be used to specify a program that doxygen should
 invoke to filter for each input file. Doxygen will invoke the filter program
 by executing (via <code>popen()</code>) the command:
\verbatim <filter> <input-file>
\endverbatim
 
 where <code>\<filter\></code>
 is the value of the \c INPUT_FILTER tag, and <code>\<input-file\></code> is the name of an
 input file. Doxygen will then use the output that the filter program writes
 to standard output.

\anchor cfg_filter_patterns
<dt>\c FILTER_PATTERNS <dd>
 \addindex FILTER_PATTERNS
 The \c FILTER_PATTERNS tag can be used to specify filters on a per file pattern
 basis.  Doxygen will compare the file name with each pattern and apply the
 filter if there is a match.  The filters are a list of the form:
 pattern=filter (like `*.cpp=my_cpp_filter`). See \ref cfg_input_filter "INPUT_FILTER" for further
 info on how filters are used. If \c FILTER_PATTERNS is empty or if
 none of the patterns match the file name, \ref cfg_input_filter "INPUT_FILTER" is 
 applied.

\anchor cfg_filter_source_files
<dt>\c FILTER_SOURCE_FILES <dd>
 \addindex FILTER_SOURCE_FILES
 If the \c FILTER_SOURCE_FILES tag is set to \c YES, the input filter (if set using
 \ref cfg_input_filter "INPUT_FILTER" ) will also be used to filter the input
 files that are used for producing the source files to browse 
 (i.e. when \ref cfg_source_browser "SOURCE_BROWSER" is set to \c YES).

\anchor cfg_filter_source_patterns
<dt>\c FILTER_SOURCE_PATTERNS <dd>
 \addindex FILTER_SOURCE_PATTERNS
 The \c FILTER_SOURCE_PATTERNS tag can be used to specify source filters per 
 file pattern. A pattern will override the setting 
 for \ref cfg_filter_patterns "FILTER_PATTERN" (if any) 
 and it is also possible to disable source filtering for a specific pattern 
 using `*.ext=` (so without naming a filter). This option only has effect when 
 \ref cfg_filter_source_files "FILTER_SOURCE_FILES" is enabled.

\anchor cfg_use_mdfile_as_mainpage
<dt>\c USE_MDFILE_AS_MAINPAGE <dd>
 \addindex USE_MDFILE_AS_MAINPAGE
If the \c USE_MD_FILE_AS_MAINPAGE tag refers to the name of a markdown file that 
is part of the input, its contents will be placed on the main page (`index.html`). 
This can be useful if you have a project on for instance GitHub and want reuse 
the introduction page also for the doxygen output.

</dl>

\section sourcebrowser_index Source browsing related options
\anchor cfg_source_browser
<dl>

<dt>\c SOURCE_BROWSER <dd>
 \addindex SOURCE_BROWSER
 If the \c SOURCE_BROWSER tag is set to \c YES then a list of source files will
 be generated. Documented entities will be cross-referenced with these sources.
 Note: To get rid of all source code in the generated output, make sure also
 \ref cfg_verbatim_headers "VERBATIM_HEADERS" is set to \c NO.

\anchor cfg_inline_sources
<dt>\c INLINE_SOURCES <dd>
 \addindex INLINE_SOURCES
 Setting the \c INLINE_SOURCES tag to \c YES will include the body
 of functions, classes and enums directly into the documentation.

\anchor cfg_strip_code_comments
<dt>\c STRIP_CODE_COMMENTS <dd>
 \addindex STRIP_CODE_COMMENTS
 Setting the \c STRIP_CODE_COMMENTS tag to \c YES (the default) will instruct
 doxygen to hide any special comment blocks from generated source code
 fragments. Normal C and C++ comments will always remain visible.

\anchor cfg_referenced_by_relation
<dt>\c REFERENCED_BY_RELATION <dd>
 \addindex REFERENCED_BY_RELATION
 If the \c REFERENCED_BY_RELATION tag is set to \c YES
 then for each documented function all documented
 functions referencing it will be listed. 

\anchor cfg_references_relation
<dt>\c REFERENCES_RELATION <dd>
 \addindex REFERENCES_RELATION
 If the \c REFERENCES_RELATION tag is set to \c YES
 then for each documented function all documented entities
 called/used by that function will be listed. 

\anchor cfg_references_link_source
<dt>\c REFERENCES_LINK_SOURCE <dd>
 \addindex REFERENCES_LINK_SOURCE
 If the \c REFERENCES_LINK_SOURCE tag is set to \c YES (the default)
 and \ref cfg_source_browser "SOURCE_BROWSER" tag is set to \c YES, then the hyperlinks from 
 functions in \ref cfg_references_relation "REFERENCES_RELATION" and
 \ref cfg_referenced_by_relation "REFERENCED_BY_RELATION" lists will 
 link to the source code.  Otherwise they will link to the documentation.

\anchor cfg_verbatim_headers
<dt>\c VERBATIM_HEADERS <dd>
 \addindex VERBATIM_HEADERS
  If the \c VERBATIM_HEADERS tag is set the \c YES (the default) then doxygen
  will generate a verbatim copy of the header file for each class for
  which an include is specified. Set to \c NO to disable this.
  \sa Section \ref cmdclass "\\class".

\anchor cfg_clang_assisted_parsig 
<dt>\c CLANG_ASSISTED_PARSING <dd>
 \addindex CLANG_ASSISTED_PARSING
  If \c CLANG_ASSISTED_PARSING is set to \c YES, then doxygen will use the 
  <a href="http://clang.llvm.org/">clang parser</a> for more acurate parsing 
  at the cost of reduced performance. This can be particularly helpful with 
  template rich C++ code for which doxygen's built-in parser lacks the 
  necessary type information.

  @note The availability of this option depends on whether or not doxygen
  was compiled with the `--with-libclang` option.

\anchor cfg_clang_options
<dt>\c CLANG_OPTIONS <dd>
 \addindex CLANG_OPTIONS 
 If clang assisted parsing is enabled you can provide the compiler with command 
 line options that you would normally use when invoking the compiler. Note that 
 the include paths will already be set by doxygen for the files and directories 
 specified at \ref cfg_input "INPUT" and \ref cfg_include_path "INCLUDE_PATH".

\anchor cfg_use_htags
<dt>\c USE_HTAGS <dd>
 \addindex USE_HTAGS
 If the \c USE_HTAGS tag is set to \c YES then the references to source code
 will point to the HTML generated by the \c htags(1) tool instead of doxygen
 built-in source browser. The \c htags tool is part of GNU's global source
 tagging system (see http://www.gnu.org/software/global/global.html).
 To use it do the following:

 -# Install the latest version of global (i.e. 4.8.6 or better)
 -# Enable \ref cfg_source_browser "SOURCE_BROWSER" and \c USE_HTAGS in the config file
 -# Make sure the \ref cfg_input "INPUT" points to the root of the source tree
 -# Run doxygen as normal

 Doxygen will invoke \c htags (and that will in turn invoke \c gtags), so these tools
 must be available from the command line (i.e. in the search path).

 The result: instead of the source browser generated by doxygen, the links to
 source code will now point to the output of \c htags.

</dl>

\section alphabetical_index Alphabetical index options
\anchor cfg_alphabetical_index
<dl>

<dt>\c ALPHABETICAL_INDEX <dd>
 \addindex ALPHABETICAL_INDEX
 If the \c ALPHABETICAL_INDEX tag is set to \c YES, an alphabetical index
 of all compounds will be generated. Enable this if the project contains 
 a lot of classes, structs, unions or interfaces.

<dt>\c COLS_IN_ALPHA_INDEX <dd>
 \anchor cfg_cols_in_alpha_index
 \addindex COLS_IN_ALPHA_INDEX
 If the alphabetical index is enabled 
 (see \ref cfg_alphabetical_index "ALPHABETICAL_INDEX") then the \c COLS_IN_ALPHA_INDEX tag can be 
 used to specify the number of columns in which this list will be split (can be a number in the range [1..20])

\anchor cfg_ignore_prefix
<dt>\c IGNORE_PREFIX <dd>
 \addindex IGNORE_PREFIX
 In case all classes in a project start with a common prefix, all classes will 
 be put under the same header in the alphabetical index.
 The \c IGNORE_PREFIX tag can be used to specify a prefix 
 (or a list of prefixes) that should be ignored while generating the index 
 headers.

</dl>
\section html_output HTML related options
\anchor cfg_generate_html
<dl>

<dt>\c GENERATE_HTML <dd>
 \addindex GENERATE_HTML
 If the \c GENERATE_HTML tag is set to \c YES (the default) doxygen will
 generate HTML output

\anchor cfg_html_output
<dt>\c HTML_OUTPUT <dd>
 \addindex HTML_OUTPUT
 The \c HTML_OUTPUT tag is used to specify where the HTML docs will be put.
 If a relative path is entered the value of \ref cfg_output_directory "OUTPUT_DIRECTORY" will be
 put in front of it. If left blank '<code>html</code>' will be used as the default path.

\anchor cfg_html_file_extension
<dt>\c HTML_FILE_EXTENSION <dd>
 \addindex HTML_FILE_EXTENSION
 The \c HTML_FILE_EXTENSION tag can be used to specify the file extension for 
 each generated HTML page (for example: <code>.htm, .php, .asp</code>). If it is left blank
 doxygen will generate files with <code>.html</code> extension.

\anchor cfg_html_header
<dt>\c HTML_HEADER <dd>      
 \addindex HTML_HEADER
 The \c HTML_HEADER tag can be used to specify a user-defined HTML 
 header file for each generated HTML page. 
 If the tag is left blank doxygen will generate a 
 standard header. 

 To get valid HTML the header file that
 includes any scripts and style sheets that doxygen
 needs, it is highly recommended to start with a default header using
\verbatim
doxygen -w html new_header.html new_footer.html new_stylesheet.css YourConfigFile
\endverbatim
 and then modify the file \c new_header.html.

 The following markers have a special meaning inside the header and footer:
 <dl>
 <dt><code>\$title</code><dd>will be replaced with the title of the page.
 <dt><code>\$datetime</code><dd>will be replaced with current the date and time.
 <dt><code>\$date</code><dd>will be replaced with the current date.
 <dt><code>\$year</code><dd>will be replaces with the current year.
 <dt><code>\$doxygenversion</code><dd>will be replaced with the version of doxygen
 <dt><code>\$projectname</code><dd>will be replaced with the name of 
            the project (see \ref cfg_project_name "PROJECT_NAME")
 <dt><code>\$projectnumber</code><dd>will be replaced with the project number
            (see \ref cfg_project_number "PROJECT_NUMBER")
 <dt><code>\$projectbrief</code><dd>will be replaced with the project brief
            description (see \ref cfg_project_brief "PROJECT_BRIEF")
 <dt><code>\$projectlogo</code><dd>will be replaced with the project logo
            (see \ref cfg_project_logo "PROJECT_LOGO")
 <dt><code>\$treeview</code><dd>will be replaced with links to 
            the javascript and style sheets needed for the navigation tree 
            (or an empty string when \ref cfg_generate_treeview "GENERATE_TREEVIEW" 
            is disabled).
 <dt><code>\$search</code><dd>will be replaced with a links to 
            the javascript and style sheets needed for the search engine 
            (or an empty string when \ref cfg_searchengine "SEARCHENGINE" 
            is disabled).
 <dt><code>\$mathjax</code><dd>will be replaced with a links to 
            the javascript and style sheets needed for the MathJax feature 
            (or an empty string when \ref cfg_use_mathjax "USE_MATHJAX" is disabled).
 <dt><code>\$relpath^</code><dd>
 If \ref cfg_create_subdirs "CREATE_SUBDIRS" is enabled, the command <code>\$relpath^</code> can be 
 used to produce a relative path to the root of the HTML output directory,
 e.g. use <code>\$relpath^doxygen.css</code>, to refer to the standard style sheet.
 </dl>

 To cope with differences in the layout of the header and footer that depend on 
 configuration settings, the header can also contain special blocks that 
 will be copied to the output or skipped depending on the configuration.
 Such blocks have the following form:
\verbatim
 <!--BEGIN BLOCKNAME-->
 Some context copied when condition BLOCKNAME holds
 <!--END BLOCKNAME-->
 <!--BEGIN !BLOCKNAME-->
 Some context copied when condition BLOCKNAME does not hold
 <!--END !BLOCKNAME-->
\endverbatim
 The following block names are supported:
 <dl>
 <dt><code>DISABLE_INDEX</code><dd>Content within this block is copied to the output
     when the \ref cfg_disable_index "DISABLE_INDEX" option is enabled (so when the index is disabled).
 <dt><code>GENERATE_TREEVIEW</code><dd>Content within this block is copied to the output
     when the \ref cfg_generate_treeview "GENERATE_TREEVIEW" option is enabled.
 <dt><code>SEARCHENGINE</code><dd>Content within this block is copied to the output
     when the \ref cfg_searchengine "SEARCHENGINE" option is enabled.
 <dt><code>PROJECT_NAME</code><dd>Content within the block is copied to the output
      when the \ref cfg_project_name "PROJECT_NAME" option is not empty.
 <dt><code>PROJECT_NUMBER</code><dd>Content within the block is copied to the output
      when the \ref cfg_project_number "PROJECT_NUMBER" option is not empty.
 <dt><code>PROJECT_BRIEF</code><dd>Content within the block is copied to the output
      when the \ref cfg_project_brief "PROJECT_BRIEF" option is not empty.
 <dt><code>PROJECT_LOGO</code><dd>Content within the block is copied to the output
      when the \ref cfg_project_logo "PROJECT_LOGO" option is not empty.
 <dt><code>TITLEAREA</code><dd>Content within this block is copied to the output
     when a title is visible at the top of each page. This is the case
     if either \ref cfg_project_name "PROJECT_NAME", 
     \ref cfg_project_brief "PROJECT_BRIEF", \ref cfg_project_logo "PROJECT_LOGO" 
     is filled in or if both \ref cfg_disable_index "DISABLE_INDEX" and 
     \ref cfg_searchengine "SEARCHENGINE" are enabled.
 </dl>

 See also section \ref doxygen_usage for information on how to generate
 the default header that doxygen normally uses.

 @note The header is subject to change so you typically
 have to regenerate the default header when upgrading to a newer version of 
 doxygen.
   
\anchor cfg_html_footer
<dt>\c HTML_FOOTER <dd>
 \addindex HTML_FOOTER
 The \c HTML_FOOTER tag can be used to specify a user-defined HTML footer for 
 each generated HTML page. 
 If the tag is left blank doxygen will generate a standard footer.

 See \ref cfg_html_header "HTML_HEADER" for more information on 
 how to generate a default footer and what special commands can be 
 used inside the footer.

 See also section \ref doxygen_usage for information on how to generate
 the default footer that doxygen normally uses.

\anchor cfg_html_stylesheet
<dt>\c HTML_STYLESHEET <dd>
 \addindex HTML_STYLESHEET

 The \c HTML_STYLESHEET tag can be used to specify a user-defined cascading 
 style sheet that is used by each HTML page. It can be used to 
 fine-tune the look of the HTML output. If left blank doxygen 
 will generate a default style sheet. 
 
 See also section \ref doxygen_usage for information on how to generate
 the style sheet that doxygen normally uses.

 \note It is recommended to use 
 \ref cfg_html_extra_stylesheet "HTML_EXTRA_STYLESHEET" instead of this tag,
 as it is more robust and 
 this tag will in the future become obsolete.

\anchor cfg_html_extra_stylesheet
<dt>\c HTML_EXTRA_STYLESHEET <dd>
 \addindex HTML_EXTRA_STYLESHEET
 The \c HTML_EXTRA_STYLESHEET tag can be used to specify an additional 
 user-defined cascading style sheet that is included after the standard 
 style sheets created by doxygen. Using this option one can overrule 
 certain style aspects. This is preferred over using \ref cfg_html_stylesheet "HTML_STYLESHEET" 
 since it does not replace the standard style sheet and is therefor more 
 robust against future updates. Doxygen will copy the style sheet file to 
 the output directory.

 Here is an example stylesheet that gives the contents area a fixed width:
\verbatim
body {
        background-color: #CCC;
        color: black;
        margin: 0;
}

div.contents {
        margin-bottom: 10px;
        padding: 12px;
        margin-left: auto;
        margin-right: auto;
        width: 960px;
        background-color: white;
        border-radius: 8px;
}

#titlearea {
        background-color: white;
}

hr.footer {
        display: none;
}

.footer {
        background-color: #AAA;
}
\endverbatim

\anchor cfg_html_extra_files
<dt>\c HTML_EXTRA_FILES <dd>
 \addindex HTML_EXTRA_FILES
 The \c HTML_EXTRA_FILES tag can be used to specify one or more extra images or 
 other source files which should be copied to the HTML output directory. Note 
 that these files will be copied to the base HTML output directory. Use the 
 <code>$relpath^</code> marker in the \ref cfg_html_header "HTML_HEADER" and/or
 \ref cfg_html_footer "HTML_FOOTER" files to load these 
 files. In the \ref cfg_html_stylesheet "HTML_STYLESHEET" file, use the file name only. Also note that 
 the files will be copied as-is; there are no commands or markers available.

\anchor cfg_html_colorstyle_hue
<dt>\c HTML_COLORSTYLE_HUE <dd>
 \addindex HTML_COLOR_STYLE_HUE
 The \c HTML_COLORSTYLE_HUE tag controls the color of the HTML output. 
 Doxygen will adjust the colors in the stylesheet and background images 
 according to this color. Hue is specified as an angle on a colorwheel, 
 see http://en.wikipedia.org/wiki/Hue for more information. 
 For instance the value 0 represents red, 60 is yellow, 120 is green, 
 180 is cyan, 240 is blue, 300 purple, and 360 is red again. 
 The allowed range is 0 to 359. 

\anchor cfg_html_colorstyle_sat
<dt>\c HTML_COLORSTYLE_SAT <dd>
 \addindex HTML_COLORSTYLE_SAT
 The \c HTML_COLORSTYLE_SAT tag controls the purity (or saturation) of 
 the colors in the HTML output. For a value of 0 the output will use 
 grayscales only. A value of 255 will produce the most vivid colors. 

\anchor cfg_html_colorstyle_gamma
<dt>\c HTML_COLORSTYLE_GAMMA <dd>
 The \c HTML_COLORSTYLE_GAMMA tag controls the gamma correction applied to 
 the luminance component of the colors in the HTML output. Values below 
 100 gradually make the output lighter, whereas values above 100 make 
 the output darker. The value divided by 100 is the actual gamma applied, 
 so 80 represents a gamma of 0.8, The value 220 represents a gamma of 2.2, 
 and 100 does not change the gamma.

\anchor cfg_html_timestamp
<dt>\c HTML_TIMESTAMP <dd>
 \addindex HTML_TIMESTAMP
 If the \c HTML_TIMESTAMP tag is set to \c YES then the footer of 
 each generated HTML page will contain the date and time when the page 
 was generated. Setting this to \c NO can help when comparing the output of 
 multiple runs.

\anchor cfg_html_align_members
<dt>\c HTML_ALIGN_MEMBERS <dd>
 \addindex HTML_ALIGN_MEMBERS
 If the \c HTML_ALIGN_MEMBERS tag is set to \c YES, the members of classes,
 files or namespaces will be aligned in HTML using tables. If set to
 \c NO a bullet list will be used. 

 <b>Note:</b>
 Setting this tag to \c NO will become obsolete in the future, since I only
 intent to support and test the aligned representation.

\anchor cfg_html_dynamic_sections
<dt>\c HTML_DYNAMIC_SECTIONS <dd>
 \addindex HTML_DYNAMIC_SECTIONS
 If the \c HTML_DYNAMIC_SECTIONS tag is set to \c YES then the generated HTML
 documentation will contain sections that can be hidden and shown after the
 page has loaded. 

\anchor cfg_html_index_num_entries
<dt>\c HTML_NUM_INDEX_ENTRIES <dd>
 \addindex HTML_NUM_INDEX_ENTRIES
 With \c HTML_INDEX_NUM_ENTRIES one can control the preferred number of 
 entries shown in the various tree structured indices initially; the user 
 can expand and collapse entries dynamically later on. Doxygen will expand 
 the tree to such a level that at most the specified number of entries are 
 visible (unless a fully collapsed tree already exceeds this amount). 
 So setting the number of entries 1 will produce a full collapsed tree by 
 default. 0 is a special value representing an infinite number of entries 
 and will result in a full expanded tree by default.

\anchor cfg_generate_docset
<dt>\c GENERATE_DOCSET <dd>
 \addindex GENERATE_DOCSET
 If the \c GENERATE_DOCSET tag is set to \c YES, additional index files
 will be generated that can be used as input for 
 <a href="http://developer.apple.com/tools/xcode/">Apple's Xcode 3
 integrated development environment</a>, introduced with OSX 10.5 (Leopard).
 To create a documentation set, doxygen will generate a Makefile in the
 HTML output directory. Running \c make will produce the docset in that
 directory and running <code>make install</code> will install the docset in 
 <code>~/Library/Developer/Shared/Documentation/DocSets</code> 
 so that Xcode will find it at startup. See
 <a href="http://developer.apple.com/tools/creatingdocsetswithdoxygen.html">
 this article</a> for more information.

\anchor cfg_docset_feedname 
<dt>\c DOCSET_FEEDNAME <dd>
 \addindex DOCSET_FEEDNAME
 When \ref cfg_generate_docset "GENERATE_DOCSET" tag is set to \c YES, this tag determines the name of the
 feed. A documentation feed provides an umbrella under which multiple
 documentation sets from a single provider (such as a company or product suite) 
 can be grouped.

\anchor cfg_docset_bundle_id
<dt>\c DOCSET_BUNDLE_ID <dd>
 When \ref cfg_generate_docset "GENERATE_DOCSET" tag is set to \c YES, this tag specifies a string that
 should uniquely identify the documentation set bundle. This should be a
 reverse domain-name style string, e.g. <code>com.mycompany.MyDocSet</code>. 
 Doxygen will append <code>.docset</code> to the name.

\anchor cfg_docset_publisher_id
<dt>\c DOCSET_PUBLISHER_ID <dd>
When \ref cfg_generate_docset "GENERATE_DOCSET" tag is set to \c YES \c DOCSET_PUBLISHER_ID
tag specifies a string that should uniquely identify 
the documentation publisher. This should be a reverse domain-name style 
string, e.g. com.mycompany.MyDocSet.documentation. 

\anchor cfg_docset_publisher_name
<dt>\c DOCSET_PUBLISHER_NAME <dd>
The \c DOCSET_PUBLISHER_NAME tag identifies the documentation publisher.

\anchor cfg_generate_htmlhelp
<dt>\c GENERATE_HTMLHELP <dd>
 \addindex GENERATE_HTMLHELP
 If the \c GENERATE_HTMLHELP tag is set to \c YES then
 doxygen generates three additional HTML index files: 
 \c index.hhp, \c index.hhc, and \c index.hhk. The \c index.hhp is a 
 project file that can be read by 
 <a href="http://www.microsoft.com/en-us/download/details.aspx?id=21138">
 Microsoft's HTML Help Workshop</a>
 on Windows.

 The HTML Help Workshop contains a compiler that can convert all HTML output 
 generated by doxygen into a single compiled HTML file (`.chm`). Compiled
 HTML files are now used as the Windows 98 help format, and will replace
 the old Windows help format (`.hlp`) on all Windows platforms in the future.
 Compressed HTML files also contain an index, a table of contents,
 and you can search for words in the documentation.
 The HTML workshop also contains a viewer for compressed HTML files.

\anchor cfg_chm_file 
<dt>\c CHM_FILE <dd>
 \addindex CHM_FILE
  If the \ref cfg_generate_htmlhelp "GENERATE_HTMLHELP" tag is set to \c YES, the \c CHM_FILE tag can
  be used to specify the file name of the resulting `.chm` file. You
  can add a path in front of the file if the result should not be
  written to the html output directory.

\anchor cfg_hhc_location 
<dt>\c HHC_LOCATION <dd>
 \addindex HHC_LOCATION
  If the \ref cfg_generate_htmlhelp "GENERATE_HTMLHELP" tag is set to \c YES, the \c HHC_LOCATION tag can
  be used to specify the location (absolute path including file name) of 
  the HTML help compiler (\c hhc.exe). If non-empty doxygen will try to run
  the HTML help compiler on the generated \c index.hhp.

\anchor cfg_generate_chi
<dt>\c GENERATE_CHI <dd>
 \addindex GENERATE_CHI
 If the \ref cfg_generate_htmlhelp "GENERATE_HTMLHELP" tag is set to \c YES, the \c GENERATE_CHI flag
 controls if a separate `.chi` index file is generated (\c YES) or that
 it should be included in the master `.chm` file (\c NO).

\anchor cfg_chm_index_encoding
<dt>\c CHM_INDEX_ENCODING <dd>
 \addindex CHM_INDEX_ENCODING
 If the \ref cfg_generate_htmlhelp "GENERATE_HTMLHELP" tag is set to \c YES, the \c CHM_INDEX_ENCODING 
 is used to encode HtmlHelp index (\c hhk), content (\c hhc) and project file 
 content. 

\anchor cfg_binary_toc
<dt>\c BINARY_TOC <dd>
 \addindex BINARY_TOC
 If the \ref cfg_generate_htmlhelp "GENERATE_HTMLHELP" tag is set to \c YES, the \c BINARY_TOC flag
 controls whether a binary table of contents is generated (\c YES) or a
 normal table of contents (\c NO) in the .chm file.

\anchor cfg_toc_expand
<dt>\c TOC_EXPAND <dd>
 \addindex TOC_EXPAND
 The \c TOC_EXPAND flag can be set to \c YES to add extra items for 
 group members to the table of contents of the HTML help documentation 
 and to the tree view.

\anchor cfg_generate_qhp
<dt>\c GENERATE_QHP <dd>
 \addindex GENERATE_QHP
 If the \c GENERATE_QHP tag is set to \c YES and both \ref cfg_qhp_namespace "QHP_NAMESPACE"
 and \ref cfg_qhp_virtual_folder "QHP_VIRTUAL_FOLDER" are set, an additional index file will
 be generated that can be used as input for Qt's qhelpgenerator
 to generate a Qt Compressed Help (`.qch`) of the generated HTML
 documentation.

\anchor cfg_qch_file
<dt>\c QCH_FILE <dd>
 \addindex QCH_FILE
 If the \ref cfg_qhg_location "QHG_LOCATION" tag is specified, the \c QCH_FILE tag can
 be used to specify the file name of the resulting `.qch` file.
 The path specified is relative to the HTML output folder.

\anchor cfg_qhp_namespace
<dt>\c QHP_NAMESPACE <dd>
 \addindex QHP_NAMESPACE
 The \c QHP_NAMESPACE tag specifies the namespace to use when generating
 Qt Help Project output. For more information please see

\anchor cfg_qhp_cust_filter_name
<dt>\c QHP_CUST_FILTER_NAME <dd>
  \addindex QHP_CUST_FILTER_NAME
  If \c QHP_CUST_FILTER_NAME is set, it specifies the name of a custom filter to add. For more information please see

\anchor cfg_qhp_cust_filter_attrs
<dt>\c QHP_CUST_FILTER_ATTRS <dd>
  \addindex QHP_CUST_FILTER_ATTRS
  The \c QHP_CUST_FILTER_ATTRIBUTES tag specifies the list of the attributes of the custom filter to add.
  For more information please see

\anchor cfg_qhg_location
<dt>\c QHG_LOCATION <dd>
 \addindex QHG_LOCATION
 If the \ref cfg_generate_qhp "GENERATE_QHP" tag is set to \c YES, the \c QHG_LOCATION tag can
 be used to specify the location of Qt's qhelpgenerator.
 If non-empty doxygen will try to run qhelpgenerator on the generated
 `.qhp` file.

\anchor cfg_generate_eclipsehelp
<dt>\c GENERATE_ECLIPSEHELP <dd>
 \addindex GENERATE_ECLIPSEHELP
 If the \c GENERATE_ECLIPSEHELP tag is set to \c YES, additional index files  
 will be generated, which together with the HTML files, form an `Eclipse` help 
 plugin. 

 To install this plugin and make it available under the help contents 
 menu in `Eclipse`, the contents of the directory containing the HTML and XML 
 files needs to be copied into the plugins directory of eclipse. The name of 
 the directory within the plugins directory should be the same as 
 the \ref cfg_eclipse_doc_id "ECLIPSE_DOC_ID" value. 

 After copying `Eclipse` needs to be restarted before the help appears.

\anchor cfg_eclipse_doc_id
<dt>\c ECLIPSE_DOC_ID <dd>
 \addindex ECLIPSE_DOC_ID
 A unique identifier for the `Eclipse` help plugin. When installing the plugin 
 the directory name containing the HTML and XML files should also have 
 this name. Each documentation set should have its own identifier.

\anchor cfg_disable_index
<dt>\c DISABLE_INDEX <dd>
 \addindex DISABLE_INDEX
 If you want full control over the layout of the generated HTML pages it
 might be necessary to disable the index and replace it with your own.
 The \c DISABLE_INDEX tag can be used to turn on/off the condensed index at
 top of each page. A value of \c NO (the default) enables the index and the
 value \c YES disables it. Since the tabs have the same information as the 
 navigation tree you can set this option to \c NO if you already set 
 \ref cfg_generate_treeview "GENERATE_TREEVIEW" to \c YES.

\anchor cfg_enum_values_per_line
<dt>\c ENUM_VALUES_PER_LINE <dd>
 \addindex ENUM_VALUES_PER_LINE
 This tag can be used to set the number of enum values (range [0,1..20]) 
 that doxygen will group on one line in the generated HTML documentation. 
 Note that a value of 0 will completely suppress the enum values from
 appearing in the overview section.

\anchor cfg_generate_treeview
<dt>\c GENERATE_TREEVIEW <dd>
 \addindex GENERATE_TREEVIEW
 The \c GENERATE_TREEVIEW tag is used to specify whether a tree-like index
 structure should be generated to display hierarchical information.
 If the tag value is set to \c YES, a side panel will be generated
 containing a tree-like index structure (just like the one that
 is generated for HTML Help). For this to work a browser that supports
 JavaScript, DHTML, CSS and frames is required (i.e. any modern browser).
 Windows users are probably better off using the HTML help feature.

 Via custom stylesheets (see \ref cfg_html_extra_stylesheet "HTML_EXTRA_STYLESHEET")
 one can further \ref doxygen_finetune "fine-tune" the look of the index.
 As an example, the default style sheet generated by doxygen has an
 example that shows how to put an image at the root of the tree instead of
 the \ref cfg_project_name "PROJECT_NAME".

\anchor cfg_treeview_width
<dt>\c TREEVIEW_WIDTH <dd>
 \addindex TREEVIEW_WIDTH
 If the treeview is enabled (see \ref cfg_generate_treeview "GENERATE_TREEVIEW") then this tag can be
 used to set the initial width (in pixels) of the frame in which the tree
 is shown.

\anchor cfg_ext_links_in_window
<dt>\c EXT_LINKS_IN_WINDOW <dd>
 \addindex EXT_LINKS_IN_WINDOW
 When the \c EXT_LINKS_IN_WINDOW option is set to \c YES doxygen will open 
 links to external symbols imported via tag files in a separate window. 

\anchor cfg_formula_fontsize
<dt>\c FORMULA_FONTSIZE <dd>
 \addindex FORMULA_FONTSIZE
 Use this tag to change the font size of \f$\mbox{\LaTeX}\f$ formulas included
 as images in the HTML documentation. The default is 10.
 when you change the font size after a successful doxygen run you need
 to manually remove any `form_*.png` images from the HTML 
 output directory to force them to be regenerated.

\anchor cfg_formula_transparent
<dt>\c FORMULA_TRANSPARENT <dd>
 \addindex FORMULA_TRANSPARENT
 Use the \c FORMULA_TRANPARENT tag to determine whether or not the images 
 generated for formulas are transparent PNGs. Transparent PNGs are 
 not supported properly for IE 6.0, but are supported on all modern browsers. 
 Note that when changing this option you need to delete any `form_*.png` files 
 in the HTML output before the changes have effect. 

\anchor cfg_use_mathjax
<dt>\c USE_MATHJAX <dd>
 \addindex USE_MATHJAX
 Enable the \c USE_MATHJAX option to render \f$\mbox{\LaTeX}\f$ formulas using MathJax 
 (see http://www.mathjax.org) which uses client side Javascript for the 
 rendering instead of using prerendered bitmaps. Use this if you do not 
 have \f$\mbox{\LaTeX}\f$ installed or if you want to formulas look prettier in the HTML 
 output. When enabled you may also need to install MathJax separately and 
 configure the path to it using the \ref cfg_mathjax_relpath "MATHJAX_RELPATH" 
 option.

\anchor cfg_mathjax_format
<dt>\c MATHJAX_FORMAT <dd>
 \addindex MATHJAX_FORMAT
 When MathJax is enabled you can set the default output format to be used for 
 the MathJax output. Supported types are HTML-CSS, NativeMML (i.e. MathML) and 
 SVG. The default value is HTML-CSS, which is slower, but has the best 
 compatibility. See 
<a href="http://docs.mathjax.org/en/latest/output.html">the MathJax site</a>
for more details.

\anchor cfg_mathjax_codefile
<dt>\c MATHJAX_CODEFILE <dd>
 \addindex MATHJAX_CODEFILE
 The \c MATHJAX_CODEFILE tag can be used to specify a file with javascript 
 pieces of code that will be used on startup of the MathJax code. 
 See 
<a href="http://docs.mathjax.org/en/latest/output.html">the MathJax site</a>
 for more details.<br>
 As an example to disable the "Math Renderer" menu item in the "Math
 Settings" menu of MathJax:
\verbatim
MATHJAX_CODEFILE = disableRenderer
\endverbatim
  with in the file \c disableRenderer:
\verbatim
  MathJax.Hub.Config({
   menuSettings: {
    showRenderer: false,
   } 
  });
\endverbatim
\anchor cfg_mathjax_relpath
<dt>\c MATHJAX_RELPATH <dd>
 \addindex MATHJAX_RELPATH
 When MathJax is enabled you need to specify the location relative to the 
 HTML output directory using the \c MATHJAX_RELPATH option. The destination 
 directory should contain the `MathJax.js` script. For instance, if the \c mathjax 
 directory is located at the same level as the HTML output directory, then 
 \c MATHJAX_RELPATH should be <code>../mathjax</code>. The default value points to 
 the MathJax Content Delivery Network so you can quickly see the result without 
 installing MathJax.  However, it is strongly recommended to install a local 
 copy of MathJax from http://www.mathjax.org before deployment.

\anchor cfg_mathjax_extensions
<dt>\c MATHJAX_EXTENSIONS <dd>
 \addindex MATHJAX_EXTENSIONS
 The \c MATHJAX_EXTENSIONS tag can be used to specify one or MathJax extension 
 names that should be enabled during MathJax rendering. For example
\verbatim
MATHJAX_EXTENSIONS     = TeX/AMSmath TeX/AMSsymbols
\endverbatim

\anchor cfg_searchengine
<dt>\c SEARCHENGINE <dd>
 \addindex SEARCHENGINE

 When the \c SEARCHENGINE tag is enabled doxygen will generate a search box
 for the HTML output. The underlying search engine uses javascript 
 and DHTML and should work on any modern browser. Note that when using
 HTML help (\ref cfg_generate_htmlhelp "GENERATE_HTMLHELP"), 
 Qt help (\ref cfg_generate_qhp "GENERATE_QHP"), or docsets
 (\ref cfg_generate_docset "GENERATE_DOCSET") there is already a search 
 function so this one should typically be disabled. For large projects 
 the javascript based search engine can be slow, then enabling 
 \ref cfg_server_based_search "SERVER_BASED_SEARCH" may provide a 
 better solution. 

 It is possible to search using the keyboard;
 to jump to the search box use `<access key> + S` (what the `<access key>` is
 depends on the OS and browser, but it is typically `<CTRL>`, `<ALT>`/`<option>`, or both).
 Inside the search box use the `<cursor down key>` to jump into the search 
 results window, the results can be navigated using the `<cursor keys>`.
 Press `<Enter>` to select an item or `<escape>` to cancel the search. The
 filter options can be selected when the cursor is inside the search box
 by pressing `<Shift>+<cursor down>`. Also here use the `<cursor keys>` to 
 select a filter and `<Enter>` or `<escape>` to activate or cancel the filter option.

\anchor cfg_server_based_search
<dt>\c SERVER_BASED_SEARCH <dd>
 \addindex SERVER_BASED_SEARCH

When the \c SERVER_BASED_SEARCH tag is enabled the search engine will be 
implemented using a web server instead of a web client using Javascript. 

There are two flavours of web server based searching depending on the 
\ref cfg_external_search "EXTERNAL_SEARCH" setting. When disabled, 
doxygen will generate a PHP script for searching and an index file used 
by the script. When \ref cfg_external_search "EXTERNAL_SEARCH" is 
enabled the indexing and searching needs to be provided by external tools. 
See \ref extsearch for details.

\anchor cfg_external_search
<dt>\c EXTERNAL_SEARCH <dd>
 \addindex EXTERNAL_SEARCH

When \c EXTERNAL_SEARCH is enabled doxygen will no longer generate the PHP 
script for searching. Instead the search results are written to an XML file 
which needs to be processed by an external indexer. Doxygen will invoke an 
external search engine pointed to by the 
\ref cfg_searchengine_url "SEARCHENGINE_URL" option to obtain 
the search results. See the section \ref extsearch for details.

\anchor cfg_searchengine_url
<dt>\c SEARCHENGINE_URL <dd>
 \addindex SEARCHENGINE_URL

The \c SEARCHENGINE_URL should point to a search engine hosted by a web server 
which will returned the search results when \ref cfg_external_search "EXTERNAL_SEARCH" 
is enabled.  See the section \ref extsearch for details.

\anchor cfg_searchdata_file
<dt>\c SEARCHDATA_FILE <dd>
 \addindex SEARCHDATA_FILE

When \ref cfg_server_based_search "SERVER_BASED_SEARCH" and 
\ref cfg_external_search "EXTERNAL_SEARCH" are both enabled the unindexed 
search data is written to a file for indexing by an external tool. With the 
\c SEARCHDATA_FILE tag the name of this file can be specified.
The default is `searchdata.xml`.

\anchor cfg_external_search_id 
<dt>\c EXTERNAL_SEARCH_ID <dd>
 \addindex EXTERNAL_SEARCH_ID

When \ref cfg_server_based_search "SERVER_BASED_SEARCH" and 
\ref cfg_external_search "EXTERNAL_SEARCH" are both enabled the 
\c EXTERNAL_SEARCH_ID tag can be used as an identifier for the project. This is 
useful in combination with \ref cfg_extra_search_mappings "EXTRA_SEARCH_MAPPINGS" 
to search through multiple projects and redirect the results back to the right project.

\anchor cfg_extra_search_mappings
<dt>\c EXTRA_SEARCH_MAPPINGS <dd>
 \addindex EXTRA_SEARCH_MAPPINGS

The \c EXTRA_SEARCH_MAPPINGS tag can be used to enable searching through doxygen 
projects other than the one defined by this configuration file, but that are 
all added to the same external search index. Each project needs to have a 
unique id set via \ref cfg_external_search_id "EXTERNAL_SEARCH_ID". 
The search mapping then maps the id of to a relative location where the 
documentation can be found. 

The format is: 
\verbatim
EXTRA_SEARCH_MAPPINGS = tagname1=loc1 tagname2=loc2 ... 
\endverbatim

 generate \f$\mbox{\LaTeX}\f$ output.

\anchor cfg_latex_output
<dt>\c LATEX_OUTPUT <dd>
 \addindex LATEX_OUTPUT
 The \c LATEX_OUTPUT tag is used to specify where the \f$\mbox{\LaTeX}\f$ 
 docs will be put.
 If a relative path is entered the value of \ref cfg_output_directory "OUTPUT_DIRECTORY" will be
 put in front of it. If left blank '`latex`' will be used as the default path.

\anchor cfg_latex_cmd_name
<dt>\c LATEX_CMD_NAME <dd>
 \addindex LATEX_CMD_NAME
 The \c LATEX_CMD_NAME tag can be used to specify the \f$\mbox{\LaTeX}\f$ command name to be invoked. 
 If left blank 'latex' will be used as the default command name.
 Note that when enabling \ref cfg_use_pdflatex "USE_PDFLATEX" this option is only used for
 generating bitmaps for formulas in the HTML output, but not in the
 \c Makefile that is written to the output directory.

\anchor cfg_makeindex_cmd_name
<dt>\c MAKEINDEX_CMD_NAME <dd>
 \addindex MAKEINDEX_CMD_NAME
 The MAKEINDEX_CMD_NAME tag can be used to specify the command name to 
 generate index for \f$\mbox{\LaTeX}\f$. If left blank '`makeindex`' will be used as the 
 default command name.

\anchor cfg_compact_latex
<dt>\c COMPACT_LATEX <dd>
 \addindex COMPACT_LATEX
 If the \c COMPACT_LATEX tag is set to \c YES doxygen generates more compact
 \f$\mbox{\LaTeX}\f$ documents. This may be useful for small projects and may help to
 save some trees in general.

\anchor cfg_paper_type
<dt>\c PAPER_TYPE <dd>
 \addindex PAPER_TYPE
 The \c PAPER_TYPE tag can be used to set the paper type that is used
 by the printer. Possible values are: 
 <ul>
 <li><code>a4</code> (210 x 297 mm).
 <li><code>letter</code> (8.5 x 11 inches).
 <li><code>legal</code> (8.5 x 14 inches).
 <li><code>executive</code> (7.25 x 10.5 inches)
 </ul> 
 If left blank \c a4 will be used.

\anchor cfg_extra_packages
<dt>\c EXTRA_PACKAGES <dd>
 \addindex EXTRA_PACKAGES
 The \c EXTRA_PACKAGES tag can be used to specify one or more \f$\mbox{\LaTeX}\f$ 
 package names that should be included in the \f$\mbox{\LaTeX}\f$ output.
 To get the times font for instance you can specify 
\verbatim
EXTRA_PACKAGES = times
\endverbatim
 If left blank no extra packages will be included.

\anchor cfg_latex_header
<dt>\c LATEX_HEADER <dd>
 \addindex LATEX_HEADER
 The \c LATEX_HEADER tag can be used to specify a personal \f$\mbox{\LaTeX}\f$ 
 header for the generated \f$\mbox{\LaTeX}\f$ document. 
 The header should contain everything until the first chapter. 

 If it is left blank doxygen will generate a 
 standard header. See section \ref doxygen_usage for information on how to 
 let doxygen write the default header to a separate file.
 
 \par Note: 
   Only use a user-defined header if you know what you are doing!

 The following commands have a special meaning inside the header:
 <code>\$title</code>, <code>\$datetime</code>, <code>\$date</code>,
 <code>\$doxygenversion</code>, <code>\$projectname</code>, 
 <code>\$projectnumber</code>. 
 Doxygen will replace them by respectively 
 the title of the page, the current date and time, only the current date,
 the version number of doxygen, the project name (see \ref cfg_project_name "PROJECT_NAME"), or the
 project number (see \ref cfg_project_number "PROJECT_NUMBER").

\anchor cfg_latex_footer
<dt>\c LATEX_FOOTER <dd>
 \addindex LATEX_FOOTER
 The \c LATEX_FOOTER tag can be used to specify a personal \f$\mbox{\LaTeX}\f$ footer for 
 the generated \f$\mbox{\LaTeX}\f$ document. The footer should contain everything after 
 the last chapter. If it is left blank doxygen will generate a 
 standard footer.
 
 \par Note: 
   Only use a user-defined footer if you know what you are doing!

\anchor cfg_latex_extra_files
<dt>\c LATEX_EXTRA_FILES <dd>
 \addindex LATEX_EXTRA_FILES
 The \c LATEX_EXTRA_FILES tag can be used to specify one or more extra images
 or other source files which should be copied to the \f$\mbox{\LaTeX}\f$ output directory.
 Note that the files will be copied as-is; there are no commands or markers
 available.

\anchor cfg_pdf_hyperlinks
<dt>\c PDF_HYPERLINKS <dd>
 \addindex PDF_HYPERLINKS

 If the \c PDF_HYPERLINKS tag is set to \c YES, the \f$\mbox{\LaTeX}\f$ that 
 is generated is prepared for conversion to PDF (using \c ps2pdf or \c pdflatex). 
 The PDF file will
 contain links (just like the HTML output) instead of page references.
 This makes the output suitable for online browsing using a PDF viewer.

\anchor cfg_use_pdflatex
<dt>\c USE_PDFLATEX <dd>
 \addindex LATEX_PDFLATEX

 If the \c LATEX_PDFLATEX tag is set to \c YES, doxygen will use
 \c pdflatex to generate the PDF file directly from the \f$\mbox{\LaTeX}\f$
 files.

\anchor cfg_latex_batchmode
<dt>\c LATEX_BATCHMODE <dd>
 \addindex LATEX_BATCHMODE

 If the \c LATEX_BATCHMODE tag is set to \c YES, doxygen will add the \c \\batchmode
 command to the generated \f$\mbox{\LaTeX}\f$ files. This will 
 instruct \f$\mbox{\LaTeX}\f$ to keep running if errors occur, instead of 
 asking the user for help. This option is also used when generating formulas 
 in HTML.

\anchor cfg_latex_bib_style 
<dt>\c LATEX_BIB_STYLE <dd>
 \addindex LATEX_BIB_STYLE

 The \c LATEX_BIB_STYLE tag can be used to specify the style to use for the

 evaluate all C-preprocessor directives found in the sources and include
 files. 

\anchor cfg_macro_expansion
<dt>\c MACRO_EXPANSION <dd>
 \addindex MACRO_EXPANSION
 If the \c MACRO_EXPANSION tag is set to \c YES doxygen will expand all macro
 names in the source code. If set to \c NO (the default) only conditional 
 compilation will be performed. Macro expansion can be done in a controlled
 way by setting \ref cfg_expand_only_predef "EXPAND_ONLY_PREDEF" to \c YES.

\anchor cfg_expand_only_predef
<dt>\c EXPAND_ONLY_PREDEF <dd>
 \addindex EXPAND_ONLY_PREDEF
 If the \c EXPAND_ONLY_PREDEF and \ref cfg_macro_expansion "MACRO_EXPANSION" tags are both set to \c YES
 then the macro expansion is limited to the macros specified with the
 \ref cfg_predefined "PREDEFINED" and \ref cfg_expand_as_defined "EXPAND_AS_DEFINED" tags.

\anchor cfg_search_includes
<dt>\c SEARCH_INCLUDES <dd>
 \addindex SEARCH_INCLUDES 
 If the \c SEARCH_INCLUDES tag is set to \c YES (the default) the includes files
 in the \ref cfg_include_path "INCLUDE_PATH" will be searched if a \c \#include is found.

\anchor cfg_include_path
<dt>\c INCLUDE_PATH <dd>
 \addindex INCLUDE_PATH
 The \c INCLUDE_PATH tag can be used to specify one or more directories that
 contain include files that are not input files but should be processed by
 the preprocessor.

\anchor cfg_include_file_patterns
<dt>\c INCLUDE_FILE_PATTERNS <dd>
 \addindex INCLUDE_FILE_PATTERNS
 You can use the \c INCLUDE_FILE_PATTERNS tag to specify one or more wildcard 
 patterns (like `*.h` and `*.hpp`) to filter out the header-files in the 
 directories. If left blank, the patterns specified with \ref cfg_file_patterns "FILE_PATTERNS" will 
 be used. 

\anchor cfg_predefined
<dt>\c PREDEFINED <dd>
 \addindex PREDEFINED
 The \c PREDEFINED tag can be used to specify one or more macro names that
 are defined before the preprocessor is started (similar to the `-D` option of
 \c gcc). The argument of the tag is a list of macros of the form:
 <code>name</code> or <code>name=definition</code> (no spaces). 
 If the definition and the \c "=" are omitted,  \c "=1" is assumed. To prevent
 a macro definition from being undefined via \c \#undef or recursively expanded
 use the <code>:=</code> operator instead of the \c = operator.

\anchor cfg_expand_as_defined
<dt>\c EXPAND_AS_DEFINED <dd>
 \addindex EXPAND_AS_DEFINED
 If the \ref cfg_macro_expansion "MACRO_EXPANSION" and
 \ref cfg_expand_only_predef "EXPAND_ONLY_PREDEF" tags are set to \c YES then
 this tag can be used to specify a list of macro names that should be expanded.
 The macro definition that is found in the sources will be used.
 Use the \ref cfg_predefined "PREDEFINED" tag if you want to use a different macro definition.

\anchor cfg_skip_function_macros
<dt>\c SKIP_FUNCTION_MACROS <dd>
 \addindex SKIP_FUNCTION_MACROS
 If the \c SKIP_FUNCTION_MACROS tag is set to \c YES (the default) then 
 doxygen's preprocessor will remove all function-like macros that are alone 
 on a line, have an all uppercase name, and do not end with a semicolon. 
 Such function macros are typically 
 used for boiler-plate code, and will confuse the parser if not removed.

\section config_extref External reference options
\anchor cfg_tagfiles
<dl>

<dt>\c TAGFILES <dd> 
 \addindex TAGFILES
 The \c TAGFILES tag can be used to specify one or more tag files. 

 See \ref external for more information about the use of tag files.

 \note
  Each tag file must have an unique name 
  (where the name does \e not include the path).
  If a tag file is not located in the directory in which doxygen 
  is run, you must also specify the path to the tagfile here.

\anchor cfg_generate_tagfile
<dt>\c GENERATE_TAGFILE <dd>
 \addindex GENERATE_TAGFILE
 When a file name is specified after \c GENERATE_TAGFILE, doxygen will create
 a tag file that is based on the input files it reads.
 See section \ref external for more information about the usage of 
 tag files.

\anchor cfg_allexternals
<dt>\c ALLEXTERNALS <dd>
 \addindex ALLEXTERNALS
 If the \c ALLEXTERNALS tag is set to \c YES all external class will be listed
 in the class index. If set to \c NO only the inherited external classes
 will be listed.

\anchor cfg_external_groups
<dt>\c EXTERNAL_GROUPS <dd>
 \addindex EXTERNAL_GROUPS
 If the \c EXTERNAL_GROUPS tag is set to \c YES all external groups will be listed
 in the modules index. If set to \c NO, only the current project's groups will
 be listed.

\anchor cfg_external_pages
<dt>\c EXTERNAL_PAGES <dd>
 \addindex EXTERNAL_PAGES
 If the \c EXTERNAL_PAGES tag is set to \c YES all external pages will be listed 
 in the related pages index. If set to \c NO, only the current project's 
 pages will be listed. 
 
\anchor cfg_perl_path
<dt>\c PERL_PATH <dd>
 \addindex PERL_PATH
 The \c PERL_PATH should be the absolute path and name of the perl script
 interpreter (i.e. the result of '<tt>which perl</tt>').

</dl>
\section config_dot Dot options
\anchor cfg_class_diagrams
<dl>

<dt>\c CLASS_DIAGRAMS <dd>
 \addindex CLASS_DIAGRAMS
 If the \c CLASS_DIAGRAMS tag is set to \c YES (the default) doxygen will
 generate a class diagram (in HTML and \f$\mbox{\LaTeX}\f$) for classes with base or
super classes. Setting the tag to \c NO turns the diagrams off. Note that 
this option also works with \ref cfg_have_dot "HAVE_DOT" disabled, but it is recommended to 
install and use \c dot, since it yields more powerful graphs. 

\anchor cfg_mscgen_path
<dt>\c MSCGEN_PATH <dd>
 \addindex MSCGEN_PATH
 You can define message sequence charts within doxygen comments using the \ref cmdmsc "\\msc" 
 command. Doxygen will then run the <a href="http://www.mcternan.me.uk/mscgen/">mscgen tool</a>) to 
 produce the chart and insert it in the documentation. The <code>MSCGEN_PATH</code> tag allows you to 
 specify the directory where the mscgen tool resides. If left empty the tool is assumed to 
 be found in the default search path.

\anchor cfg_have_dot
<dt>\c HAVE_DOT <dd>
 \addindex HAVE_DOT
 If you set the \c HAVE_DOT tag to \c YES then doxygen will assume the \c dot tool is
 available from the \c path. This tool is part of 
 <a href=" http://www.graphviz.org/">Graphviz</a>, a graph 
 visualization toolkit from AT\&T and Lucent Bell Labs. The other options in 
 this section have no effect if this option is set to \c NO (the default)

\anchor cfg_dot_num_threads
<dt>\c DOT_NUM_THREADS <dd>
 \addindex DOT_NUM_THREADS
 The \c DOT_NUM_THREADS specifies the number of \c dot invocations doxygen is 
 allowed to run in parallel. When set to \c 0 (the default) doxygen will 
 base this on the number of processors available in the system. You can set it 
 explicitly to a value larger than 0 to get control over the balance 
 between CPU load and processing speed.  

\anchor cfg_dot_fontname
<dt>\c DOT_FONTNAME <dd>
 \addindex DOT_FONTNAME
 By default doxygen will use the Helvetica font for all dot files that 
 doxygen generates. 
 When you want a differently looking font you can specify the font name 
 using \c DOT_FONTNAME. You need to make sure dot is able to find the font, 
 which can be done by putting it in a standard location or by setting the 
 \c DOTFONTPATH environment variable or by setting \ref cfg_dot_fontpath "DOT_FONTPATH" to the 
 directory containing the font. 

\anchor cfg_dot_fontsize
<dt>\c DOT_FONTSIZE <dd>
The \c DOT_FONTSIZE tag can be used to set the size of the font of dot graphs.
The default size is 10pt. 

\anchor cfg_dot_fontpath
<dt>\c DOT_FONTPATH <dd>
 \addindex DOT_FONTPATH
 By default doxygen will tell \c dot to use the output directory to look for the 
 \c FreeSans.ttf font (which doxygen will put there itself). If you specify a 
 different font using \ref cfg_dot_fontname "DOT_FONTNAME" you can set the path where \c dot 
 can find it using this tag.
 
\anchor cfg_class_graph
<dt>\c CLASS_GRAPH <dd>
 \addindex CLASS_GRAPH
 If the \c CLASS_GRAPH and \ref cfg_have_dot "HAVE_DOT" tags are set to \c YES then doxygen
 will generate a graph for each documented class showing the direct and
 indirect inheritance relations. Setting this tag to \c YES will force 
 the \ref cfg_class_diagrams "CLASS_DIAGRAMS" tag to \c NO.

\anchor cfg_collaboration_graph
<dt>\c COLLABORATION_GRAPH <dd>
 \addindex COLLABORATION_GRAPH
 If the \c COLLABORATION_GRAPH and \ref cfg_have_dot "HAVE_DOT" are set to \c YES then doxygen
 will generate a graph for each documented class showing the direct and
 indirect implementation dependencies (inheritance, containment, and
 class references variables) of the class with other documented classes.

\anchor cfg_group_graphs
<dt>\c GROUP_GRAPHS <dd>
 \addindex GROUP_GRAPHS
 If the \c GROUP_GRAPHS and \ref cfg_have_dot "HAVE_DOT" tags are set to \c YES then doxygen
 will generate a graph for groups, showing the direct groups dependencies.

\anchor cfg_uml_look
<dt>\c UML_LOOK <dd>
 \addindex UML_LOOK
 If the \c UML_LOOK tag is set to \c YES doxygen will generate inheritance and
 collaboration diagrams in a style similar to the OMG's Unified Modeling
 Language.

\anchor cfg_uml_limit_num_fields
<dt>\c UML_LIMIT_NUM_FIELDS <dd>
 \addindex UML_LIMIT_NUM_FIELDS
 If the \ref cfg_uml_look "UML_LOOK" tag is enabled, the fields and methods are shown inside 
 the class node. If there are many fields or methods and many nodes the 
 graph may become too big to be useful. The \c UML_LIMIT_NUM_FIELDS 
 threshold limits the number of items for each type to make the size more 
 manageable. Set this to 0 for no limit. Note that the threshold may be
 exceeded by 50% before the limit is enforced. So when you set the threshold
 to 10, up to 15 fields may appear, but if the number exceeds 15, the
 total amount of fields shown is limited to 10.

\anchor cfg_template_relations
<dt>\c TEMPLATE_RELATIONS <dd>
 \addindex TEMPLATE_RELATIONS
 If the \c TEMPLATE_RELATIONS and \ref cfg_have_dot "HAVE_DOT" tags are set to \c YES then 
 doxygen will show the relations between templates and their instances.

\anchor cfg_hide_undoc_relations
<dt>\c HIDE_UNDOC_RELATIONS <dd>
 \addindex HIDE_UNDOC_RELATIONS
 If set to \c YES, the inheritance and collaboration graphs will hide
 inheritance and usage relations if the target is undocumented
 or is not a class.

\anchor cfg_include_graph
<dt>\c INCLUDE_GRAPH <dd>
 \addindex INCLUDE_GRAPH 
 If the \ref cfg_enable_preprocessing "ENABLE_PREPROCESSING",
 \ref cfg_search_includes "SEARCH_INCLUDES", \ref cfg_include_graph "INCLUDE_GRAPH",
 and \ref cfg_have_dot "HAVE_DOT"
 tags are set to \c YES then doxygen will generate a graph for each documented file
 showing the direct and indirect include dependencies of the file with other
 documented files.

\anchor cfg_included_by_graph
<dt>\c INCLUDED_BY_GRAPH <dd>
 \addindex INCLUDED_BY_GRAPH 
 If the \ref cfg_enable_preprocessing "ENABLE_PREPROCESSING",
 \ref cfg_search_includes "SEARCH_INCLUDES", \ref cfg_include_graph "INCLUDED_BY_GRAPH", and
 \ref cfg_have_dot "HAVE_DOT" tags are set to \c YES then doxygen will generate a graph for each
 documented header file showing the documented files that directly or indirectly
 include this file.

\anchor cfg_call_graph
<dt>\c CALL_GRAPH <dd>
 \addindex CALL_GRAPH
 If the \c CALL_GRAPH and \ref cfg_have_dot "HAVE_DOT" tags are set to \c YES then doxygen will 
 generate a call dependency graph for every global function or class method. 
 Note that enabling this option will significantly increase the time of a run.
 So in most cases it will be better to enable call graphs for selected 
 functions only using the \ref cmdcallgraph "\\callgraph" command.

\anchor cfg_caller_graph
<dt>\c CALLER_GRAPH <dd>
 \addindex CALLER_GRAPH
 If the \c CALLER_GRAPH and \ref cfg_have_dot "HAVE_DOT" tags are set to \c YES then doxygen will 
 generate a caller dependency graph for every global function or class method. 
 Note that enabling this option will significantly increase the time of a run.
 So in most cases it will be better to enable caller graphs for selected 
 functions only using the \ref cmdcallergraph "\\callergraph" command.

\anchor cfg_graphical_hierarchy
<dt>\c GRAPHICAL_HIERARCHY <dd>
 \addindex GRAPHICAL_HIERARCHY
 If the \c GRAPHICAL_HIERARCHY and \ref cfg_have_dot "HAVE_DOT" tags are set to \c YES then 
 doxygen will graphical hierarchy of all classes instead of a textual one.

\anchor cfg_directory_graph
<dt>\c DIRECTORY_GRAPH <dd>
 \addindex DIRECTORY_GRAPH		    
 If the \c DIRECTORY_GRAPH, and \ref cfg_have_dot "HAVE_DOT" options are set 
 to \c YES then doxygen will show the dependencies a directory has on other directories
 in a graphical way. The dependency relations are determined by the \c \#include
 relations between the files in the directories.

\anchor cfg_dot_graph_max_nodes 
<dt>\c DOT_GRAPH_MAX_NODES <dd>
 \addindex DOT_GRAPH_MAX_NODES
 The \c DOT_GRAPH_MAX_NODES tag can be used to set the maximum number of 
 nodes that will be shown in the graph. If the number of nodes in a graph
 becomes larger than this value, doxygen will truncate the graph, which is 
 visualized by representing a node as a red box. Note that doxygen if the number
 of direct children of the root node in a graph is already larger than
 \c DOT_GRAPH_MAX_NODES then the graph will not be shown at all. Also note
 that the size of a graph can be further restricted by \ref cfg_max_dot_graph_depth "MAX_DOT_GRAPH_DEPTH".

\anchor cfg_max_dot_graph_depth
<dt>\c MAX_DOT_GRAPH_DEPTH <dd>
 \addindex MAX_DOT_GRAPH_DEPTH
 The \c MAX_DOT_GRAPH_DEPTH tag can be used to set the maximum depth of the 
 graphs generated by \c dot. A depth value of 3 means that only nodes reachable
 from the root by following a path via at most 3 edges will be shown. Nodes
 that lay further from the root node will be omitted. Note that setting this
 option to 1 or 2 may greatly reduce the computation time needed for large
 code bases. Also note that the size of a graph can be further restricted by
 \ref cfg_dot_graph_max_nodes "DOT_GRAPH_MAX_NODES". Using a depth of 0 means no depth restriction (the default).

\anchor cfg_dot_image_format
<dt>\c DOT_IMAGE_FORMAT <dd>
 \addindex DOT_IMAGE_FORMAT
 The \c DOT_IMAGE_FORMAT tag can be used to set the image format of the images
 generated by \c dot. Possible values are \c svg, \c png, \c jpg, or \c gif.
 If left blank png will be used.
 \note If you choose \c svg you need to set 
 \ref cfg_html_file_extension "HTML_FILE_EXTENSION" to \c xhtml in order to make the SVG files
 visible in IE 9+ (other browsers do not have this requirement).

\anchor cfg_interactive_svg
<dt>\c INTERACTIVE_SVG <dd>
 If \ref cfg_dot_image_format "DOT_IMAGE_FORMAT" is set to \c svg, then this option can be set to \c YES to
 enable generation of interactive SVG images that allow zooming and panning. 
 Note that this requires a modern browser other than Internet Explorer. 
 Tested and working are Firefox, Chrome, Safari, and Opera.
 \note For IE 9+ you need to set \ref cfg_html_file_extension "HTML_FILE_EXTENSION" to xhtml in order 
 to make the SVG files visible. Older versions of IE do not have SVG support.

\anchor cfg_dot_path
<dt>\c DOT_PATH <dd>
 \addindex DOT_PATH
 This tag can be used to specify the path where the \c dot tool can be found. 
 If left blank, it is assumed the \c dot tool can be found in the \c path. 

\anchor cfg_dotfile_dirs
<dt>\c DOTFILE_DIRS <dd>
 \addindex DOTFILE_DIRS
 This tag can be used to specify one or more directories that 
 contain dot files that are included in the documentation (see the
 \ref cmddotfile "\\dotfile" command).

\anchor cfg_mscfile_dirs
<dt>\c MSCFILE_DIRS <dd>
 \addindex MSCFILE_DIRS
 This tag can be used to specify one or more directories that 
 contain msc files that are included in the documentation (see the
 \ref cmdmscfile "\\mscfile" command).

\anchor cfg_dot_transparent
<dt>\c DOT_TRANSPARENT <dd>
 \addindex DOT_TRANSPARENT
 Set the \c DOT_TRANSPARENT tag to \c YES to generate images with a transparent
 background. This is disabled by default, because dot on Windows does not 
 seem to support this out of the box. Warning: Depending on the platform used, 
 enabling this option may lead to badly anti-aliased labels on the edges of 
 a graph (i.e. they become hard to read). 
 
\anchor cfg_dot_multi_targets
<dt>\c DOT_MULTI_TARGETS <dd>
 \addindex DOT_MULTI_TARGET
 Set the \c DOT_MULTI_TARGETS tag to \c YES allow dot to generate multiple output
 files in one run (i.e. multiple -o and -T options on the command line). This
 makes \c dot run faster, but since only newer versions of \c dot (>1.8.10)
 support this, this feature is disabled by default.

\anchor cfg_generate_legend 
<dt>\c GENERATE_LEGEND <dd>
 \addindex GENERATE_LEGEND
 If the \c GENERATE_LEGEND tag is set to \c YES (the default) doxygen will
 generate a legend page explaining the meaning of the various boxes and
 arrows in the dot generated graphs.

\anchor cfg_dot_cleanup
<dt>\c DOT_CLEANUP <dd>
 \addindex DOT_CLEANUP
If the \c DOT_CLEANUP tag is set to \c YES (the default) doxygen will
remove the intermediate dot files that are used to generate the various graphs.

<h2>Examples</h2>

Suppose you have a simple project consisting of two files: a source file 
\c example.cc and a header file \c example.h.
Then a minimal configuration file is as simple as:
\verbatim
INPUT            = example.cc example.h
\endverbatim

Assuming the example makes use of Qt classes and \c perl is located 
in <code>/usr/bin</code>, a more realistic configuration file would be:
\verbatim
PROJECT_NAME     = Example
INPUT            = example.cc example.h
WARNINGS         = YES
TAGFILES         = qt.tag
PERL_PATH        = /usr/local/bin/perl
SEARCHENGINE     = NO
\endverbatim

To generate the documentation for the 
<a href="http://www.stack.nl/~dimitri/qdbttabular/index.html">QdbtTabular</a> package
I have used the following configuration file:
\verbatim
PROJECT_NAME     = QdbtTabular
