\section config_format Format

A configuration file is a free-form ASCII text file with a structure
that is similar to that of a Makefile, 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 begin with the \# character and end 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 <code>=</code> character and one or more values. If the same tag
is assigned more than once, the last assignment overwrites any earlier
assignment. For options 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 (&quot;...&quot;).
Multiple lines can be concatenated by inserting a backslash (\\)
as the last character of a line. Environment variables can be expanded 
using the pattern \c \$(ENV_VARIABLE_NAME).

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_project_name
<dl>

<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_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
 2 levels of 10 sub-directories 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:
 Brazilian, Catalan, Chinese, Croatian, Czech, Danish, Dutch, Finnish, French,
 German, Greek, Hungarian, Italian, Japanese, Korean, Lithuanian, Norwegian, 
 Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovene, Spanish, 
 Swedish, and Ukrainian.

\anchor cfg_use_windows_encoding
<dt>\c USE_WINDOWS_ENCODING <dd>
 \addindex USE_WINDOWS_ENCODING
 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 \c USE_WINDOWS_ENCODING tag to \c YES
 forces the Windows encoding, (this is the default for the Windows binary),
 whereas setting the tag to \c NO uses a Unix-style encoding (the default for
 all platforms other than Windows).

\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 JavaDoc).
 Set to 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 \c HIDE_UNDOC_MEMBERS and \c 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 \c 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 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 \c 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
 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_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 NO.

\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 NO (the default), the 
  Javadoc-style will behave just like the Qt-style comments.

\anchor cfg_multiline_cpp_is_brief
<dt>\c MULTILINE_CPP_IS_BRIEF <dd>
 \addindex MULTILINE_CPP_IS_BRIEF
  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.
  Note that setting this tag to 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 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.

\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_distribute_group_doc
<dt>\c DISTRIBUTE_GROUP_DOC <dd>
 \addindex DISTRIBUTE_GROUP_DOC
 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.

\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 \\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.

\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 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. 

\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. 

</dl>

\section config_build Build related options
\anchor cfg_extract_all
<dl>

<dt>\c EXTRACT_ALL <dd>
 \addindex EXTRACT_ALL
 If the \c EXTRACT_ALL tag is set to \c 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 \c EXTRACT_PRIVATE and \c EXTRACT_STATIC tags are set to \c YES

 \par Note: 
 This will also disable the warnings about undocumented members 
 that are normally produced when \c WARNINGS is set to \c YES

\anchor cfg_extract_private
<dt>\c EXTRACT_PRIVATE <dd>
 \addindex EXTRACT_PRIVATE
 If the \c EXTRACT_PRIVATE tag is set to \c YES all private members of a 
 class will be included in the documentation.

\anchor cfg_extract_static
<dt>\c EXTRACT_STATIC <dd>
 \addindex EXTRACT_STATIC
 If the \c EXTRACT_STATIC tag is set to \c YES all static members of a file
 will be included in the documentation.

\anchor cfg_extract_local_classes
<dt>\c EXTRACT_LOCAL_CLASSES <dd>
 \addindex EXTRACT_LOCAL_CLASSES
 If the \c EXTRACT_LOCAL_CLASSES tag is set to \c 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. Does not
 have any effect for Java sources.

\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 \c 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
 undocumented classes.
 If set to \c NO (the default) these classes will be included in the
 various overviews.
 This option has no effect if \c EXTRACT_ALL is enabled.

\anchor cfg_hide_friend_compounds
<dt>\c HIDE_FRIEND_COMPOUNDS <dd>
 \addindex HIDE_FRIEND_COMPOUNDS
 If the \c HIDE_FRIEND_COMPOUNDS tag is set to \c YES, Doxygen will hide all
 friend (class|struct|union) declarations.
 If set to \c NO (the default) these declarations will be included in the
 documentation.
 
\anchor cfg_hide_in_body_docs
<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_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 show members with their full class and namespace scopes in the
 documentation. If set to \c YES the scope will be hidden. 

\anchor cfg_show_include_files
<dt>\c SHOW_INCLUDE_FILES <dd>
 \addindex SHOW_INCLUDE_FILES
 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.

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

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

 \ref cmdendif "\\endif" 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

\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 \c OUTPUT_DIRECTORY will be
 put in front of it. If left blank `html' 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: .htm, .php, .asp). If it is left blank
 doxygen will generate files with .html 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. To get valid HTML the header file
 should contain at least a \c \<HTML\> and a \c \<BODY\> tag, but it is
 good idea to include the style sheet that is generated by doxygen as well. 
 Minimal example:
\verbatim
  <HTML>
    <HEAD>
      <TITLE>My title</TITLE>
      <LINK HREF="doxygen.css" REL="stylesheet" TYPE="text/css">
    </HEAD>
    <BODY BGCOLOR="#FFFFFF">
\endverbatim
 If the tag is left blank doxygen will generate a 
 standard header. 

 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>, and
 <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 \c PROJECT_NAME), or the
 project number (see \c PROJECT_NUMBER). 

 If \c 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 \$relpath\$doxygen.css, to refer to the standard style sheet.
   
 See also section \ref doxygen_usage for information on how to generate
 the default header that doxygen normally uses.
   
\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. To get valid HTML the header file should contain
 at least a \c \</BODY\> and a \c \</HTML\> tag. A minimal example:
\verbatim
    </BODY>
  </HTML>
\endverbatim
 If the tag is left blank doxygen will generate a standard footer.

 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 \c PROJECT_NAME), or the
 project number (see \c PROJECT_NUMBER).

 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 the tag is 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.

\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_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://msdn.microsoft.com/library/default.asp?url=/library/en-us/htmlhelp/html/vsconHH1Start.asp">
 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 compressed HTML file (.chm). Compressed
 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.

<dt>\c GENERATE_PERLMOD <dd>
 \addindex GENERATE_PERLMOD
 If the \c GENERATE_PERLMOD tag is set to \c 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.

\anchor cfg_perlmod_latex
<dt>\c PERLMOD_LATEX <dd>
 \addindex PERLMOD_LATEX
 If the \c PERLMOD_LATEX tag is set to \c 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. 

\anchor cfg_perlmod_pretty
<dt>\c PERLMOD_PRETTY <dd>
 \addindex PERLMOD_PRETTY
 If the \c PERLMOD_PRETTY tag is set to \c 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 \c NO the size of the Perl module output will be much smaller
 and Perl will parse it just the same. 

\anchor cfg_perlmod_makevar_prefix
<dt>\c PERLMOD_MAKEVAR_PREFIX <dd>
 \addindex PERLMOD_MAKEVAR_PREFIX
 The names of the make variables in the generated doxyrules.make file 
 are prefixed with the string contained in \c PERLMOD_MAKEVAR_PREFIX. 
 This is useful so different doxyrules.make files included by the same
 Makefile don't overwrite each other's variables.

</dl>

\section config_prepro Preprocessor related options
\anchor cfg_enable_preprocessing
<dl>

<dt>\c ENABLE_PREPROCESSING <dd>
 \addindex ENABLE_PREPROCESSING
 If the \c ENABLE_PREPROCESSING tag is set to \c YES (the default) doxygen will
 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 \c 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 \c MACRO_EXPANSION tags are both set to YES
 then the macro expansion is limited to the macros specified with the
 \c PREDEFINED and \c 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 \c INCLUDE_PATH (see below) will be searched if a \#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_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
 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 "=" are omitted,  "=1" is assumed.

\anchor cfg_expand_as_defined
<dt>\c EXPAND_AS_DEFINED <dd>
 \addindex EXPAND_AS_DEFINED
 If the \c MACRO_EXPANSION and \c 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 \c 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. 

</dl>
\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 tagfiles. 
 
 See section \ref doxytag_usage for more information about the usage of 
 tag files.
 
 Optionally an initial location of the external documentation 
 can be added for each tagfile.
 The format of a tag file without this location is as follows:
 <pre>
TAGFILES = file1 file2 ... </pre>
 Adding location for the tag files is done as follows:
 <pre>
TAGFILES = file1=loc1 "file2 = loc2" ... </pre>
 where \c loc1 and \c loc2 can be relative or absolute paths or URLs, 
 If a location is present for each tag, the installdox tool (see 
 section \ref installdox_usage for more information) does not
 have to be run to correct the links.

 \par Note:
  Each tag file must have a 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 doxytag_usage 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_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 is superseded by the HAVE_DOT option below. 
 This is only a fallback. It is recommended to install and use dot, 
 since it yields more powerful graphs. 

\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 dot tool is
 available from the path. This tool is part of 
 <a href="http://www.research.att.com/sw/tools/graphviz/">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_class_graph
<dt>\c CLASS_GRAPH <dd>
 \addindex CLASS_GRAPH
 If the \c CLASS_GRAPH and \c 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
 the \c CLASS_DIAGRAMS tag to NO.

\anchor cfg_collaboration_graph
<dt>\c COLLABORATION_GRAPH <dd>
 \addindex COLLABORATION_GRAPH
 If the \c COLLABORATION_GRAPH and \c HAVE_DOT tags 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_template_relations
<dt>\c TEMPLATE_RELATIONS <dd>
 \addindex TEMPLATE_RELATIONS
 If the \c TEMPLATE_RELATIONS and \c 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 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 \c ENABLE_PREPROCESSING, \c SEARCH_INCLUDES, \c INCLUDE_GRAPH, and \c 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 \c ENABLE_PREPROCESSING, \c SEARCH_INCLUDES, \c INCLUDED_BY_GRAPH, and
 \c 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 \c 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 \\callgraph command.

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

\anchor cfg_dot_image_format
<dt>\c DOT_IMAGE_FORMAT <dd>
 \addindex DOT_IMAGE_FORMAT
 The DOT_IMAGE_FORMAT tag can be used to set the image format of the images
 generated by dot. Possible values are gif, jpg, and png.
 If left blank png will be used.

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

\anchor cfg_max_dot_graph_height 
<dt>\c MAX_DOT_GRAPH_HEIGHT <dd>
 \addindex MAX_DOT_GRAPH_HEIGHT
 The \c MAX_DOT_GRAPH_HEIGHT tag can be used to set the maximum allows height
 (in pixels) of the graphs generated by dot. If a graph becomes larger than
 this value, doxygen will try to truncate the graph, so that it fits within
 the specified constraint. Beware that most browsers cannot cope with very
 large images.

\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 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 a graph may be further truncated if the graph's image dimensions are 
not sufficient to fit the graph (see 
\ref cfg_max_dot_graph_width "MAX_DOT_GRAPH_WIDTH" and 
\ref cfg_max_dot_graph_height "MAX_DOT_GRAPH_HEIGHT"). 
If 0 is used for the depth value (the default), the graph is 
not depth-constraint.

\anchor cfg_max_dot_graph_width 
<dt>\c MAX_DOT_GRAPH_WIDTH <dd>
 \addindex MAX_DOT_GRAPH_WIDTH
 The \c MAX_DOT_GRAPH_WIDTH tag can be used to set the maximum allowed width
 (in pixels) of the graphs generated by dot. If a graph becomes larger than
 this value, doxygen will try to truncate the graph, so that it fits within
 the specified constraint. Beware that most browsers cannot cope with very
 large images.

\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.


</dl>
\section config_search Search engine options
\anchor cfg_searchengine
<dl>

<dt>\c SEARCHENGINE <dd>
 \addindex SEARCHENGINE
 The \c SEARCHENGINE tag specifies whether or not the HTML output should
 contain a search facility. Possible values are \c YES and \c NO. 
 If set to YES, doxygen will produce a search index and a PHP script
 to search through the index. For this to work the documentation should
 be viewed via a web-server running PHP version 4.1.0 or higher.
 (See http://www.php.net/manual/en/installation.php for installation 
 instructions).

<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 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/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
OUTPUT_DIRECTORY = html
WARNINGS         = YES
INPUT            = examples/examples.doc src
FILE_PATTERNS    = *.cc *.h
INCLUDE_PATH     = examples
TAGFILES         = qt.tag
PERL_PATH        = /usr/local/bin/perl
SEARCHENGINE     = YES
\endverbatim

To regenerate the Qt-1.44 documentation from the sources, you could use the
following config file:
\verbatim

Here doxygen's preprocessor is used to substitute some
macro names that are normally substituted by the C preprocessor,
but without doing full macro expansion.
