# Doxyfile 1.4.2

 # 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 (" ")

 #---------------------------------------------------------------------------

 # Project related configuration options

 #---------------------------------------------------------------------------

 # The PROJECT_NAME tag is a single word (or a sequence of words surrounded 

 # by quotes) that should identify the project.

 PROJECT_NAME           = @PACKAGE_NAME@

 # 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.

 PROJECT_NUMBER         = @PACKAGE_VERSION@

 # 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.

 OUTPUT_DIRECTORY       = 

 # 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.

 CREATE_SUBDIRS         = NO

 # 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.

 OUTPUT_LANGUAGE        = English

 # 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.

 BRIEF_MEMBER_DESC      = YES

 # 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.

 REPEAT_BRIEF           = NO

 # 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"

 INLINE_INHERITED_MEMB  = NO

 # 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.

 FULL_PATH_NAMES        = YES

 # 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.

 STRIP_FROM_PATH        = @abs_top_srcdir@

 # 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.

 STRIP_FROM_INC_PATH    = @abs_top_srcdir@

 # If the SHORT_NAMES tag is set to YES, doxygen will generate much shorter

 SHORT_NAMES            = YES

 # If the JAVADOC_AUTOBRIEF tag is set to YES then Doxygen 

 # will interpret the first line (until the first dot) of a JavaDoc-style

 # explicit @brief command for a brief description.

 JAVADOC_AUTOBRIEF      = NO

 # 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.

 MULTILINE_CPP_IS_BRIEF = NO

 # If the DETAILS_AT_TOP tag is set to YES then Doxygen

 # If member grouping is used in the documentation and the DISTRIBUTE_GROUP_DOC

 DISTRIBUTE_GROUP_DOC   = NO

 # If the SEPARATE_MEMBER_PAGES tag is set to YES, then doxygen will produce

 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
