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.

<option type='string' id='PROJECT_NAME' format='string' docs='
The PROJECT_NAME tag is a single word (or sequence of words) that should
identify the project. Note that if you do not use Doxywizard you need
to put quotes around the project name if it contains spaces.' defval='My Project'/>
<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='PROJECT_BRIEF' format='string' docs='
Using the PROJECT_BRIEF tag one can provide an optional one line description
for a project that appears at the top of each page and should give viewer
a quick idea about the purpose of the project. Keep the description short.
' defval=''/>
<option type='string' id='PROJECT_LOGO' format='file' docs='
With the PROJECT_LOGO tag one can specify an logo or icon that is
included in the documentation. The maximum height of the logo should not
exceed 55 pixels and the maximum width should not exceed 200 pixels.
Doxygen will copy the logo to the output directory.
' 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.

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 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.

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.

<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 "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.

<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

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

<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, CSharp, 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. Note that for custom extensions
you also need to set FILE_PATTERNS otherwise the files are not read by doxygen.

<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 makes the inheritance and collaboration
diagrams that involve STL classes more complete and accurate.

If you use Microsoft'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'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 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='INLINE_GROUPED_CLASSES' docs='
When the INLINE_GROUPED_CLASSES tag is set to YES, classes, structs and
unions are shown inside the group in which they are included (e.g. using
@ingroup) instead of on a separate page (for HTML and Man pages) or
section (for LaTeX and RTF).
' defval='0'/>
<option type='bool' id='INLINE_SIMPLE_STRUCTS' docs='
When the INLINE_SIMPLE_STRUCTS tag is set to YES, structs, classes, and
unions with only public data fields will be shown inline in the documentation
of the scope in which they are defined (i.e. file, namespace, or group
documentation), provided this scope is documented. If set to NO (the default),
structs, classes, and unions are shown on a separate page (for HTML and Man
pages) or section (for LaTeX and RTF).' defval='0'/>
<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'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 (<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 penalty.
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 roughly 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

When the SEARCHENGINE tag is enabled doxygen will generate a search box

and DHTML and should work on any modern browser. Note that when using
HTML help (GENERATE_HTMLHELP), Qt help (GENERATE_QHP), or docsets
(GENERATE_DOCSET) there is already a search function so this one should
typically be disabled. For large projects the javascript based search engine
can be slow, then enabling SERVER_BASED_SEARCH may provide a better solution.

<option type='bool' id='SERVER_BASED_SEARCH' docs='
When the SERVER_BASED_SEARCH tag is enabled the search engine will be
implemented using a PHP enabled web server instead of at the web client

file to put on the web server. The advantage of the server
based approach is that it scales better to large projects and allows
full text search. The disadvantages are that it is more difficult to setup
and does not have live searching capabilities.
