+    <option type='string' id='DOXYFILE_ENCODING' format='string' docs='
+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 libiconv (or the 
+iconv built into libc) for the transcoding. See 
+http://www.gnu.org/software/libiconv for the list of possible encodings. 
+' defval='UTF-8'/>
+    <option type='string' id='PROJECT_NAME' format='string' docs='
+The PROJECT_NAME tag is a single word (or a sequence of words surrounded 
+by quotes) that should identify the project. ' defval=''/>
+    <option type='string' id='PROJECT_NUMBER' format='string' docs='
+The 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. 
+' defval=''/>
+    <option type='string' id='OUTPUT_DIRECTORY' format='dir' docs='
+The OUTPUT_DIRECTORY tag is used to specify the (relative or absolute) 
+base path where the generated documentation will be put. 
+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. 
+' defval=''/>
+    <option type='bool' id='CREATE_SUBDIRS' docs='
+If the CREATE_SUBDIRS tag is set to 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 cause performance problems for the file system. 
+' defval='0'/>
+    <option type='enum' id='OUTPUT_LANGUAGE' defval='English' docs='
+The 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, Chinese-Traditional, 
+Croatian, Czech, Danish, Dutch, Farsi, Finnish, French, German, Greek, 
+Hungarian, Italian, Japanese, Japanese-en (Japanese with English messages), 
+Korean, Korean-en, Lithuanian, Norwegian, Macedonian, Persian, Polish, 
+Portuguese, Romanian, Russian, Serbian, Serbian-Cyrilic, Slovak, Slovene, 
+Spanish, Swedish, and Ukrainian.

+    <option type='bool' id='BRIEF_MEMBER_DESC' docs='
+If the BRIEF_MEMBER_DESC tag is set to YES (the default) Doxygen will 
+include brief member descriptions after the members that are listed in 
+the file and class documentation (similar to JavaDoc). 
+Set to NO to disable this. 
+' defval='1'/>
+    <option type='bool' id='REPEAT_BRIEF' docs='
+If the REPEAT_BRIEF tag is set to YES (the default) Doxygen will prepend

+Note: if both HIDE_UNDOC_MEMBERS and BRIEF_MEMBER_DESC are set to NO, the 
+brief descriptions will be completely suppressed. 
+' defval='1'/>
+    <option type='list' id='ABBREVIATE_BRIEF' format='string' docs='
+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 (&quot;$name&quot; is automatically 
+replaced with the name of the entity): &quot;The $name class&quot; &quot;The $name widget&quot;

+If the ALWAYS_DETAILED_SEC and REPEAT_BRIEF tags are both set to YES then 
+Doxygen will generate a detailed section even if there is only a brief 
+description. 
+' defval='0'/>
+    <option type='bool' id='INLINE_INHERITED_MEMB' docs='
+If the INLINE_INHERITED_MEMB tag is set to 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. 
+' defval='0'/>
+    <option type='bool' id='FULL_PATH_NAMES' docs='
+If the FULL_PATH_NAMES tag is set to YES then Doxygen will prepend the full 
+path before files name in the file list and in the header files. If set 
+to NO the shortest path that makes the file name unique will be used. 
+' defval='1'/>
+    <option type='list' id='STRIP_FROM_PATH' format='string' docs='
+If the FULL_PATH_NAMES tag is set to YES then the 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.

+    </option>
+    <option type='list' id='STRIP_FROM_INC_PATH' format='string' docs='
+The 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. 
+'>
+    </option>
+    <option type='bool' id='SHORT_NAMES' docs='
+If the SHORT_NAMES tag is set to YES, doxygen will generate much shorter 
+(but less readable) file names. This can be useful is your file systems 
+doesn&apos;t support long names like on DOS, Mac, or CD-ROM. 
+' defval='0'/>
+    <option type='bool' id='JAVADOC_AUTOBRIEF' docs='
+If the JAVADOC_AUTOBRIEF tag is set to YES then Doxygen 
+will interpret the first line (until the first dot) of a JavaDoc-style 
+comment as the brief description. If set to NO, the JavaDoc 
+comments will behave just like regular Qt-style comments 
+(thus requiring an explicit @brief command for a brief description.) 
+' defval='0'/>
+    <option type='bool' id='QT_AUTOBRIEF' docs='
+If the QT_AUTOBRIEF tag is set to YES then Doxygen will 
+interpret the first line (until the first dot) of a Qt-style 
+comment as the brief description. If set to NO, the comments 
+will behave just like regular Qt-style comments (thus requiring 
+an explicit \brief command for a brief description.) 
+' defval='0'/>
+    <option type='bool' id='MULTILINE_CPP_IS_BRIEF' docs='
+The MULTILINE_CPP_IS_BRIEF tag can be set to YES to make Doxygen 
+treat a multi-line C++ special comment block (i.e. a block of //! or /// 
+comments) as a brief description. This used to be the default behaviour. 
+The new default is to treat a multi-line C++ comment block as a detailed 
+description. Set this tag to YES if you prefer the old behaviour instead. 
+' defval='0'/>
+    <option type='bool' id='INHERIT_DOCS' docs='
+If the INHERIT_DOCS tag is set to YES (the default) then an undocumented 
+member inherits the documentation from any documented member that it 
+re-implements. 
+' defval='1'/>
+    <option type='bool' id='SEPARATE_MEMBER_PAGES' docs='
+If the SEPARATE_MEMBER_PAGES tag is set to YES, then doxygen will produce 
+a new page for each member. If set to NO, the documentation of a member will 
+be part of the file/class/namespace that contains it. 
+' defval='0'/>
+    <option type='int' id='TAB_SIZE' docs='
+The 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. 
+' minval='1' maxval='16' defval='8'/>
+    <option type='list' id='ALIASES' format='string' docs='
+This tag can be used to specify a number of aliases that acts 
+as commands in the documentation. An alias has the form &quot;name=value&quot;. 
+For example adding &quot;sideeffect=\par Side Effects:\n&quot; will allow you to 
+put the command \sideeffect (or @sideeffect) in the documentation, which 
+will result in a user-defined paragraph with heading &quot;Side Effects:&quot;. 
+You can put \n&apos;s in the value part of an alias to insert newlines. 
+'>
+    </option>
+    <option type='bool' id='OPTIMIZE_OUTPUT_FOR_C' docs='
+Set the OPTIMIZE_OUTPUT_FOR_C tag to 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. 
+' defval='0'/>
+    <option type='bool' id='OPTIMIZE_OUTPUT_JAVA' docs='
+Set the OPTIMIZE_OUTPUT_JAVA tag to YES if your project consists of Java 
+sources only. Doxygen will then generate output that is more tailored for 
+Java. For instance, namespaces will be presented as packages, qualified 
+scopes will look different, etc. 
+' defval='0'/>
+    <option type='bool' id='OPTIMIZE_FOR_FORTRAN' docs='
+Set the OPTIMIZE_FOR_FORTRAN tag to YES if your project consists of Fortran 
+sources only. Doxygen will then generate output that is more tailored for 
+Fortran. 
+' defval='0'/>
+    <option type='bool' id='OPTIMIZE_OUTPUT_VHDL' docs='
+Set the OPTIMIZE_OUTPUT_VHDL tag to YES if your project consists of VHDL 
+sources. Doxygen will then generate output that is tailored for 
+VHDL. 
+' defval='0'/>
+    <option type='list' id='EXTENSION_MAPPING' format='string' docs='
+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, C, C++. For instance to make doxygen treat 
+.inc files as Fortran files (default is PHP), and .f files as C (default is Fortran), 
+use: inc=Fortran f=C 
+'>
+    </option>
+    <option type='bool' id='BUILTIN_STL_SUPPORT' docs='
+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 YES in order to let doxygen match functions declarations and 
+definitions whose arguments contain STL classes (e.g. func(std::string); v.s. 
+func(std::string) {}). This also make the inheritance and collaboration 
+diagrams that involve STL classes more complete and accurate. 
+' defval='0'/>
+    <option type='bool' id='CPP_CLI_SUPPORT' docs='
+If you use Microsoft&apos;s C++/CLI language, you should set this option to YES to 
+enable parsing support. 
+' defval='0'/>
+    <option type='bool' id='SIP_SUPPORT' docs='
+Set the SIP_SUPPORT tag to YES if your project consists of sip 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. 
+' defval='0'/>
+    <option type='bool' id='IDL_PROPERTY_SUPPORT' docs='
+For Microsoft&apos;s IDL there are propget and propput attributes to indicate getter 
+and setter methods for a property. Setting this option to 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 NO. 
+' defval='1'/>
+    <option type='bool' id='DISTRIBUTE_GROUP_DOC' docs='
+If member grouping is used in the documentation and the DISTRIBUTE_GROUP_DOC 
+tag is set to 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. 
+' defval='0'/>
+    <option type='bool' id='SUBGROUPING' docs='
+Set the SUBGROUPING tag to 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 
+NO to prevent subgrouping. Alternatively, this can be done per class using 
+the \nosubgrouping command. 
+' defval='1'/>
+    <option type='bool' id='TYPEDEF_HIDES_STRUCT' docs='
+When 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 
+typedef struct TypeS {} TypeT, will appear in the documentation as a struct 
+with name TypeT. When disabled the typedef will appear as a member of a file, 
+namespace, or class. And the struct will be named TypeS. This can typically 
+be useful for C code in case the coding convention dictates that all compound 
+types are typedef&apos;ed and only the typedef is referenced, never the tag name. 
+' defval='0'/>
+    <option type='int' id='SYMBOL_CACHE_SIZE' docs='
+The SYMBOL_CACHE_SIZE determines the size of the internal cache use to 
+determine which symbols to keep in memory and which to flush to disk. 
+When the cache is full, less often used symbols will be written to disk. 
+For small to medium size projects (&lt;1000 input files) the default value is 
+probably good enough. For larger projects a too small cache size can cause 
+doxygen to be busy swapping symbols to and from disk most of the time 
+causing a significant performance penality. 
+If the system has enough physical memory increasing the cache will improve the 
+performance by keeping more symbols in memory. Note that the value works on 
+a logarithmic scale so increasing the size by one will rougly double the 
+memory usage. The cache size is given by this formula: 
+2^(16+SYMBOL_CACHE_SIZE). The valid range is 0..9, the default is 0, 
+corresponding to a cache size of 2^16 = 65536 symbols 
+' minval='0' maxval='9' defval='0'/>

+  <group name='Build' docs='Build related configuration options'>
+    <option type='bool' id='EXTRACT_ALL' docs='
+If the EXTRACT_ALL tag is set to YES doxygen will assume all entities in 
+documentation are documented, even if no documentation was available. 
+Private class members and static file members will be hidden unless 
+the EXTRACT_PRIVATE and EXTRACT_STATIC tags are set to YES 
+' defval='0'/>
+    <option type='bool' id='EXTRACT_PRIVATE' docs='
+If the EXTRACT_PRIVATE tag is set to YES all private members of a class 
+will be included in the documentation. 
+' defval='0'/>
+    <option type='bool' id='EXTRACT_STATIC' docs='
+If the EXTRACT_STATIC tag is set to YES all static members of a file 
+will be included in the documentation. 
+' defval='0'/>
+    <option type='bool' id='EXTRACT_LOCAL_CLASSES' docs='
+If the EXTRACT_LOCAL_CLASSES tag is set to YES classes (and structs) 
+defined locally in source files will be included in the documentation. 
+If set to NO only classes defined in header files are included. 
+' defval='1'/>
+    <option type='bool' id='EXTRACT_LOCAL_METHODS' docs='
+This flag is only useful for Objective-C code. When set to YES local 
+methods, which are defined in the implementation section but not in 
+the interface are included in the documentation. 
+If set to NO (the default) only methods in the interface are included. 
+' defval='0'/>
+    <option type='bool' id='EXTRACT_ANON_NSPACES' docs='
+If this flag is set to YES, the members of anonymous namespaces will be 
+extracted and appear in the documentation as a namespace called 
+&apos;anonymous_namespace{file}&apos;, where file will be replaced with the base 
+name of the file that contains the anonymous namespace. By default 
+anonymous namespace are hidden. 
+' defval='0'/>
+    <option type='bool' id='HIDE_UNDOC_MEMBERS' docs='
+If the HIDE_UNDOC_MEMBERS tag is set to YES, Doxygen will hide all 
+undocumented members of documented classes, files or namespaces. 
+If set to NO (the default) these members will be included in the 
+various overviews, but no documentation section is generated. 
+This option has no effect if EXTRACT_ALL is enabled. 
+' defval='0'/>
+    <option type='bool' id='HIDE_UNDOC_CLASSES' docs='
+If the HIDE_UNDOC_CLASSES tag is set to YES, Doxygen will hide all 
+undocumented classes that are normally visible in the class hierarchy. 
+If set to NO (the default) these classes will be included in the various 
+overviews. This option has no effect if EXTRACT_ALL is enabled. 
+' defval='0'/>
+    <option type='bool' id='HIDE_FRIEND_COMPOUNDS' docs='
+If the HIDE_FRIEND_COMPOUNDS tag is set to YES, Doxygen will hide all 
+friend (class|struct|union) declarations. 
+If set to NO (the default) these declarations will be included in the 
+documentation. 
+' defval='0'/>
+    <option type='bool' id='HIDE_IN_BODY_DOCS' docs='
+If the HIDE_IN_BODY_DOCS tag is set to YES, Doxygen will hide any 
+documentation blocks found inside the body of a function. 
+If set to NO (the default) these blocks will be appended to the 
+function&apos;s detailed documentation block. 
+' defval='0'/>
+    <option type='bool' id='INTERNAL_DOCS' docs='
+The INTERNAL_DOCS tag determines if documentation 
+that is typed after a \internal command is included. If the tag is set 
+to NO (the default) then the documentation will be excluded. 
+Set it to YES to include the internal documentation. 
+' defval='0'/>
+    <option type='bool' id='CASE_SENSE_NAMES' docs='
+If the CASE_SENSE_NAMES tag is set to NO then Doxygen will only generate 
+file names in lower-case letters. If set to 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 
+and Mac users are advised to set this option to NO. 
+' defval='0' altdefval='portable_fileSystemIsCaseSensitive()'/>
+    <option type='bool' id='HIDE_SCOPE_NAMES' docs='
+If the HIDE_SCOPE_NAMES tag is set to NO (the default) then Doxygen

+alphabetically by member name. If set to NO the members will appear in 
+declaration order. 
+' defval='1'/>
+    <option type='bool' id='SORT_BRIEF_DOCS' docs='
+If the SORT_BRIEF_DOCS tag is set to YES then doxygen will sort the

+declaration order. 
+' defval='0'/>
+    <option type='bool' id='SORT_GROUP_NAMES' docs='
+If the SORT_GROUP_NAMES tag is set to YES then doxygen will sort the

+    <option type='int' id='MAX_INITIALIZER_LINES' docs='
+The MAX_INITIALIZER_LINES tag determines the maximum number of lines 
+the initial value of a variable or define consists of for it to appear in 
+the documentation. 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 initializer of individual variables and defines in the 
+documentation can be controlled using \showinitializer or \hideinitializer 
+command in the documentation regardless of this setting. 
+' minval='0' maxval='10000' defval='30'/>
+    <option type='bool' id='SHOW_USED_FILES' docs='
+Set the SHOW_USED_FILES tag to NO to disable the list of files generated

+' defval='1'/>
+    <option type='string' id='FILE_VERSION_FILTER' format='file' docs='
+The 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 
+popen()) the command &lt;command&gt; &lt;input-file&gt;, where &lt;command&gt; is the value of 
+the FILE_VERSION_FILTER tag, and &lt;input-file&gt; is the name of an input file
