# This file describes the settings to be used by the documentation system

 # doxygen (www.doxygen.org) for a project

 #

 # All text after a hash (#) is considered a comment and will be ignored

 # The format is:

 #       TAG = value [value, ...]

 # For lists items can also be appended using:

 #       TAG += value [value, ...]

 # Values that contain spaces should be placed between quotes (" ")

 # 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.

 # 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.

 # 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.

 # 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: 

 # Brazilian, Catalan, Chinese, Chinese-Traditional, Croatian, Czech, Danish, 

 # Dutch, Finnish, French, German, Greek, Hungarian, Italian, Japanese, 

 # Japanese-en (Japanese with English messages), Korean, Korean-en, Norwegian, 

 # Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovene, Spanish, 

 # Swedish, and Ukrainian.

 # This tag can be used to specify the encoding used in the generated output. 

 # The encoding is not always determined by the language that is chosen, 

 # but also whether or not the output is meant for Windows or non-Windows users. 

 # In case there is a difference, setting the USE_WINDOWS_ENCODING tag to YES 

 # forces the Windows encoding (this is the default for the Windows binary), 

 # whereas setting the tag to NO uses a Unix-style encoding (the default for 

 # all platforms other than Windows).

 USE_WINDOWS_ENCODING   = NO

 # 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.

 # If the REPEAT_BRIEF tag is set to YES (the default) Doxygen will prepend 

 # the brief description of a member or function before the detailed description. 

 # Note: if both HIDE_UNDOC_MEMBERS and BRIEF_MEMBER_DESC are set to NO, the 

 # brief descriptions will be completely suppressed.

 # 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"

 # 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.

 # 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.

 # 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.

 # 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 the Qt-style comments (thus requiring an 

 # explicit @brief command for a brief description.

 # If the DETAILS_AT_TOP tag is set to YES then Doxygen 

 # will output the detailed description near the top, like JavaDoc.

 # If set to NO, the detailed description appears after the member 

 # documentation.

 # 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.

 # 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.

 SEPARATE_MEMBER_PAGES  = NO

 # 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.

 TAB_SIZE               = 8

 # This tag can be used to specify a number of aliases that acts 

 # as commands in the documentation. An alias has the form "name=value". 

 # For example adding "sideeffect=\par Side Effects:\n" will allow you to 

 # put the command \sideeffect (or @sideeffect) in the documentation, which 

 # will result in a user-defined paragraph with heading "Side Effects:". 

 # You can put \n's in the value part of an alias to insert newlines.

 ALIASES                = 

 # 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.

 OPTIMIZE_OUTPUT_FOR_C  = NO

 # 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.

 OPTIMIZE_OUTPUT_JAVA   = NO

 # 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.

 # 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

 # If the EXTRACT_PRIVATE tag is set to YES all private members of a class 

 # will be included in the documentation.

 # If the EXTRACT_STATIC tag is set to YES all static members of a file 

 # will be included in the documentation.

 # 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.

 # 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.

 # 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.

 # 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.

 # 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's detailed documentation block.

 # If the HIDE_SCOPE_NAMES tag is set to NO (the default) then Doxygen 

 # will show members with their full class and namespace scopes in the 

 # documentation. If set to YES the scope will be hidden.

 # If the SHOW_INCLUDE_FILES tag is set to YES (the default) then Doxygen 

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

 # of that file.

 # If the INLINE_INFO tag is set to YES (the default) then a tag [inline] 

 # is inserted in the documentation for inline members.

 # If the SORT_MEMBER_DOCS tag is set to YES (the default) then doxygen 

 # will sort the (detailed) documentation of file and class members 

 # alphabetically by member name. If set to NO the members will appear in 

 # declaration order.

 # If the SORT_BRIEF_DOCS tag is set to YES then doxygen will sort the 

 # brief documentation of file, namespace and class members alphabetically 

 # by member name. If set to NO (the default) the members will appear in 

 # declaration order.

 # The GENERATE_TODOLIST tag can be used to enable (YES) or 

 # disable (NO) the todo list. This list is created by putting \todo 

 # commands in the documentation.

 # The GENERATE_TESTLIST tag can be used to enable (YES) or 

 # disable (NO) the test list. This list is created by putting \test 

 # commands in the documentation.

 # The GENERATE_BUGLIST tag can be used to enable (YES) or 

 # disable (NO) the bug list. This list is created by putting \bug 

 # commands in the documentation.

 # The GENERATE_DEPRECATEDLIST tag can be used to enable (YES) or 

 # disable (NO) the deprecated list. This list is created by putting 

 # \deprecated commands in the documentation.

 # The ENABLED_SECTIONS tag can be used to enable conditional 

 # documentation sections, marked by \if sectionname ... \endif.

 # 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.

 # The QUIET tag can be used to turn on/off the messages that are generated 

 # by doxygen. Possible values are YES and NO. If left blank NO is used.

 # The WARNINGS tag can be used to turn on/off the warning messages that are 

 # generated by doxygen. Possible values are YES and NO. If left blank 

 # NO is used.

 # If WARN_IF_UNDOCUMENTED is set to YES, then doxygen will generate warnings 

 # for undocumented members. If EXTRACT_ALL is set to YES then this flag will 

 # automatically be disabled.

 # If WARN_IF_DOC_ERROR is set to 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.

 # This WARN_NO_PARAMDOC option can be abled to get warnings for 

 # functions that are documented, but have no documentation for their parameters 

 # or return value. If set to NO (the default) doxygen will only warn about 

 # wrong or incomplete parameter documentation, but not about the absence of 

 # documentation.

 # The WARN_FORMAT tag determines the format of the warning messages that 

 # doxygen can produce. The string should contain the $file, $line, and $text 

 # tags, which will be replaced by the file and line number from which the 

 # warning originated and the warning text. Optionally the format may contain 

 # $version, which will be replaced by the version of the file (if it could 

 # be obtained via FILE_VERSION_FILTER)

 # The 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 stderr.

 # The EXCLUDE tag can be used to specify files and/or directories that should 

 # excluded from the INPUT source files. This way you can easily exclude a 

 # subdirectory from a directory tree whose root is specified with the INPUT tag.

 # The EXCLUDE_SYMLINKS tag can be used select whether or not files or 

 # directories that are symbolic links (a Unix filesystem feature) are excluded 

 # from the input.

 # If the value of the INPUT tag contains directories, you can use the 

 # EXCLUDE_PATTERNS tag to specify one or more wildcard patterns to exclude 

 # certain files from those directories.

 # If the EXAMPLE_RECURSIVE tag is set to YES then subdirectories will be 

 # searched for input files to be used with the \include or \dontinclude 

 # commands irrespective of the value of the RECURSIVE tag. 

 # Possible values are YES and NO. If left blank NO is used.

 # The 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 INPUT_FILTER for further 

 # info on how filters are used. If FILTER_PATTERNS is empty, INPUT_FILTER 

 # is applied to all files.

 # If the FILTER_SOURCE_FILES tag is set to YES, the input filter (if set using 

 # INPUT_FILTER) will be used to filter the input files when producing source 

 # files to browse (i.e. when SOURCE_BROWSER is set to YES).

 # If the SOURCE_BROWSER tag is set to 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 

 # VERBATIM_HEADERS is set to NO.

 # Setting the INLINE_SOURCES tag to YES will include the body 

 # of functions and classes directly in the documentation.

 # Setting the STRIP_CODE_COMMENTS tag to 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.

 # If the REFERENCED_BY_RELATION tag is set to YES (the default) 

 # then for each documented function all documented 

 # functions referencing it will be listed.

 # If the REFERENCES_RELATION tag is set to YES (the default) 

 # then for each documented function all documented entities 

 # called/used by that function will be listed.

 # If the ALPHABETICAL_INDEX tag is set to YES, an alphabetical index 

 # of all compounds will be generated. Enable this if the project 

 # contains a lot of classes, structs, unions or interfaces.

 # If the alphabetical index is enabled (see ALPHABETICAL_INDEX) then 

 # the 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])

 # 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 IGNORE_PREFIX tag can be used to specify one or more prefixes that 

 # should be ignored while generating the index headers.

 # If the GENERATE_HTML tag is set to YES (the default) Doxygen will 

 # generate HTML output.

 # The HTML_OUTPUT tag is used to specify where the HTML docs will be put. 

 # If a relative path is entered the value of OUTPUT_DIRECTORY will be 

 # put in front of it. If left blank `html' will be used as the default path.

 # The HTML_FILE_EXTENSION tag can be used to specify the file extension for 

 # each generated HTML page (for example: .htm,.php,.asp). If it is left blank 

 # doxygen will generate files with .html extension.

 # The HTML_HEADER tag can be used to specify a personal HTML header for 

 # each generated HTML page. If it is left blank doxygen will generate a 

 # standard header.

 # The HTML_FOOTER tag can be used to specify a personal HTML footer for 

 # each generated HTML page. If it is left blank doxygen will generate a 

 # standard footer.

 # The 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 the tag is left blank doxygen 

 # will generate a default style sheet. Note that doxygen will try to copy 

 # the style sheet file to the HTML output directory, so don't put your own 

 # stylesheet in the HTML output directory as well, or it will be erased!

 # If the HTML_ALIGN_MEMBERS tag is set to YES, the members of classes, 

 # files or namespaces will be aligned in HTML using tables. If set to 

 # NO a bullet list will be used.

 # If the GENERATE_HTMLHELP tag is set to YES, the 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.

 # If the GENERATE_HTMLHELP tag is set to YES, the HHC_LOCATION tag can 

 # be used to specify the location (absolute path including file name) of 

 # the HTML help compiler (hhc.exe). If non-empty doxygen will try to run 

 # the HTML help compiler on the generated index.hhp.

 # If the GENERATE_HTMLHELP tag is set to YES, the GENERATE_CHI flag 

 # controls if a separate .chi index file is generated (YES) or that 

 # it should be included in the master .chm file (NO).

 # The TOC_EXPAND flag can be set to YES to add extra items for group members 

 # to the contents of the HTML help documentation and to the tree view.

 # This tag can be used to set the number of enum values (range [1..20]) 

 # that doxygen will group on one line in the generated HTML documentation.

 # If the GENERATE_LATEX tag is set to YES (the default) Doxygen will 

 # generate Latex output.

 # The LATEX_OUTPUT tag is used to specify where the LaTeX docs will be put. 

 # If a relative path is entered the value of OUTPUT_DIRECTORY will be 

 # put in front of it. If left blank `latex' will be used as the default path.

 # The LATEX_CMD_NAME tag can be used to specify the LaTeX command name to be 

 # invoked. If left blank `latex' will be used as the default command name.

 # The MAKEINDEX_CMD_NAME tag can be used to specify the command name to 

 # generate index for LaTeX. If left blank `makeindex' will be used as the 

 # default command name.

 # If the COMPACT_LATEX tag is set to YES Doxygen generates more compact 

 # LaTeX documents. This may be useful for small projects and may help to 

 # save some trees in general.

 # The PAPER_TYPE tag can be used to set the paper type that is used 

 # by the printer. Possible values are: a4, a4wide, letter, legal and 

 # executive. If left blank a4wide will be used.

 # The EXTRA_PACKAGES tag can be to specify one or more names of LaTeX 

 # packages that should be included in the LaTeX output.

 # The LATEX_HEADER tag can be used to specify a personal LaTeX header for 

 # the generated latex document. The header should contain everything until 

 # the first chapter. If it is left blank doxygen will generate a 

 # standard header. Notice: only use this tag if you know what you are doing!

 # If the PDF_HYPERLINKS tag is set to YES, the LaTeX that is generated 

 # is prepared for conversion to pdf (using ps2pdf). 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.

 # If the USE_PDFLATEX tag is set to YES, pdflatex will be used instead of 

 # plain latex in the generated Makefile. Set this option to YES to get a 

 # higher quality PDF documentation.

 # If the LATEX_BATCHMODE tag is set to YES, doxygen will add the \\batchmode. 

 # command to the generated LaTeX files. This will instruct LaTeX to keep 

 # running if errors occur, instead of asking the user for help. 

 # This option is also used when generating formulas in HTML.

 # If LATEX_HIDE_INDICES is set to YES then doxygen will not 

 # include the index chapters (such as File Index, Compound Index, etc.) 

 # in the output.

 # If the GENERATE_RTF tag is set to YES Doxygen will generate RTF output 

 # The RTF output is optimized for Word 97 and may not look very pretty with 

 # other RTF readers or editors.

 # The RTF_OUTPUT tag is used to specify where the RTF docs will be put. 

 # If a relative path is entered the value of OUTPUT_DIRECTORY will be 

 # put in front of it. If left blank `rtf' will be used as the default path.

 # If the COMPACT_RTF tag is set to YES Doxygen generates more compact 

 # RTF documents. This may be useful for small projects and may help to 

 # save some trees in general.

 # If the RTF_HYPERLINKS tag is set to YES, the RTF that is generated 

 # will contain hyperlink fields. The RTF file will 

 # contain links (just like the HTML output) instead of page references. 

 # This makes the output suitable for online browsing using WORD or other 

 # programs which support those fields. 

 # Note: wordpad (write) and others do not support links.

 # Load stylesheet definitions from file. Syntax is similar to doxygen's 

 # config file, i.e. a series of assignments. You only have to provide 

 # replacements, missing definitions are set to their default value.

 # Set optional variables used in the generation of an rtf document. 

 # Syntax is similar to doxygen's config file.

 # If the GENERATE_MAN tag is set to YES (the default) Doxygen will 

 # generate man pages

 # The MAN_OUTPUT tag is used to specify where the man pages will be put. 

 # If a relative path is entered the value of OUTPUT_DIRECTORY will be 

 # put in front of it. If left blank `man' will be used as the default path.

 # The MAN_EXTENSION tag determines the extension that is added to 

 # the generated man pages (default is the subroutine's section .3)

 # If the MAN_LINKS tag is set to YES and Doxygen generates man output, 

 # then it will generate one additional man file for each entity 

 # documented in the real man page(s). These additional files 

 # only source the real man page, but without them the man command 

 # would be unable to find the correct page. The default is NO.

 # If the GENERATE_XML tag is set to YES Doxygen will 

 # generate an XML file that captures the structure of 

 # the code including all documentation.

 # The XML_OUTPUT tag is used to specify where the XML pages will be put. 

 # If a relative path is entered the value of OUTPUT_DIRECTORY will be 

 # put in front of it. If left blank `xml' will be used as the default path.

 # The XML_SCHEMA tag can be used to specify an XML schema, 

 # which can be used by a validating XML parser to check the 

 # syntax of the XML files.

 # The XML_DTD tag can be used to specify an XML DTD, 

 # which can be used by a validating XML parser to check the 

 # syntax of the XML files.

 # If the XML_PROGRAMLISTING tag is set to YES Doxygen will 

 # dump the program listings (including syntax highlighting 

 # and cross-referencing information) to the XML output. Note that 

 # enabling this will significantly increase the size of the XML output.

 # If the GENERATE_AUTOGEN_DEF tag is set to YES Doxygen will 

 # generate an AutoGen Definitions (see autogen.sf.net) file 

 # that captures the structure of the code including all 

 # documentation. Note that this feature is still experimental 

 # and incomplete at the moment.

 # If the GENERATE_PERLMOD tag is set to YES Doxygen will 

 # generate a Perl module file that captures the structure of 

 # the code including all documentation. Note that this 

 # feature is still experimental and incomplete at the 

 # moment.

 # If the PERLMOD_LATEX tag is set to YES Doxygen will generate 

 # the necessary Makefile rules, Perl scripts and LaTeX code to be able 

 # to generate PDF and DVI output from the Perl module output.

 # If the PERLMOD_PRETTY tag is set to YES the Perl module output will be 

 # nicely formatted so it can be parsed by a human reader.  This is useful 

 # if you want to understand what is going on.  On the other hand, if this 

 # tag is set to NO the size of the Perl module output will be much smaller 

 # and Perl will parse it just the same.

 # The names of the make variables in the generated doxyrules.make file 

 # are prefixed with the string contained in PERLMOD_MAKEVAR_PREFIX. 

 # This is useful so different doxyrules.make files included by the same 

 # Makefile don't overwrite each other's variables.

 # If the ENABLE_PREPROCESSING tag is set to YES (the default) Doxygen will 

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

 # files.

 # If the MACRO_EXPANSION tag is set to YES Doxygen will expand all macro 

 # names in the source code. If set to NO (the default) only conditional 

 # compilation will be performed. Macro expansion can be done in a controlled 

 # way by setting EXPAND_ONLY_PREDEF to YES.

 # If the EXPAND_ONLY_PREDEF and MACRO_EXPANSION tags are both set to YES 

 # then the macro expansion is limited to the macros specified with the 

 # PREDEFINED and EXPAND_AS_PREDEFINED tags.

 # If the SEARCH_INCLUDES tag is set to YES (the default) the includes files 

 # in the INCLUDE_PATH (see below) will be search if a #include is found.

 # The 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.

 # You can use the 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 FILE_PATTERNS will 

 # be used.

 # The 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 

 # gcc). The argument of the tag is a list of macros of the form: name 

 # or name=definition (no spaces). If the definition and the = are 

 # omitted =1 is assumed. To prevent a macro definition from being 

 # undefined via #undef or recursively expanded use the := operator 

 # instead of the = operator.

 # If the MACRO_EXPANSION and EXPAND_ONLY_PREDEF tags are set to 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 PREDEFINED tag if you want to use a different macro definition.

 # If the SKIP_FUNCTION_MACROS tag is set to 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.

 # If the ALLEXTERNALS tag is set to YES all external classes will be listed 

 # in the class index. If set to NO only the inherited external classes 

 # will be listed.

 # If the EXTERNAL_GROUPS tag is set to YES all external groups will be listed 

 # in the modules index. If set to NO, only the current project's groups will 

 # be listed.

 # The PERL_PATH should be the absolute path and name of the perl script 

 # interpreter (i.e. the result of `which perl').

 # If you set the HAVE_DOT tag to YES then doxygen will assume the dot tool is 

 # available from the path. This tool is part of Graphviz, 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 NO (the default)

 # If the COLLABORATION_GRAPH and HAVE_DOT tags are set to 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.

 # If the GROUP_GRAPHS and HAVE_DOT tags are set to YES then doxygen 

 # will generate a graph for groups, showing the direct groups dependencies

 # If the UML_LOOK tag is set to YES doxygen will generate inheritance and 

 # collaboration diagrams in a style similar to the OMG's Unified Modeling 

 # Language.

 # If set to YES, the inheritance and collaboration graphs will show the 

 # relations between templates and their instances.

 # If the ENABLE_PREPROCESSING, SEARCH_INCLUDES, INCLUDE_GRAPH, and HAVE_DOT 

 # tags are set to 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.

 # If the ENABLE_PREPROCESSING, SEARCH_INCLUDES, INCLUDED_BY_GRAPH, and 

 # HAVE_DOT tags are set to YES then doxygen will generate a graph for each 

 # documented header file showing the documented files that directly or 

 # indirectly include this file.

 # If the CALL_GRAPH and HAVE_DOT tags are set to 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.
