\subsection cmdaddtogroup \addtogroup [(title)] \addindex \addtogroup Defines a group just like \ref cmddefgroup "\\defgroup", but in contrast to that command using the same \ more than once will not result in a warning, but rather one group with a merged documentation and the first title found in any of the commands. The title is optional, so this command can also be used to add a number of entities to an existing group using \@{ and \@} like this: \verbatim /*! \addtogroup mygrp * Additional documentation for group `mygrp' * @{ */ /*! * A function */ void func1() { } /*! Another function */ void func2() { } /*! @} */ \endverbatim \sa page \ref grouping "Grouping", sections \ref cmddefgroup "\\defgroup", \ref cmdingroup "\\ingroup" and \ref cmdweakgroup "\\weakgroup". \subsection cmdclass \class [] [] \addindex \class Indicates that a comment block contains documentation for a class with name \. Optionally a header file and a header name can be specified. If the header-file is specified, a link to a verbatim copy of the header will be included in the HTML documentation. The \ argument can be used to overwrite the name of the link that is used in the class documentation to something other than \. This can be useful if the include name is not located on the default include path (like \). With the \ argument you can also specify how the include statement should look like, by adding either quotes or sharp brackets around the name. Sharp brackets are used if just the name is given. \par Example: \verbinclude class.h \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\subsection cmddef \def \addindex \def Indicates that a comment block contains documentation for a \c #define macro. \par Example: \verbinclude define.h \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\subsection cmddefgroup \defgroup (group title) \addindex \defgroup Indicates that a comment block contains documentation for a \ref modules "group" of classes, files or namespaces. This can be used to categorize classes, files or namespaces, and document those categories. You can also use groups as members of other groups, thus building a hierarchy of groups. The \ argument should be a single-word identifier. \sa page \ref grouping "Grouping", sections \ref cmdingroup "\\ingroup", \ref cmdaddtogroup "\\addtogroup", \ref cmdweakgroup "\\weakgroup".
\subsection cmdenum \enum \addindex \enum Indicates that a comment block contains documentation for an enumeration, with name \. If the enum is a member of a class and the documentation block is located outside the class definition, the scope of the class should be specified as well. If a comment block is located directly in front of an enum declaration, the \\enum comment may be omitted. \par Note: The type of an anonymous enum cannot be documented, but the values of an anonymous enum can. \par Example: \verbinclude enum.h \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\subsection cmdexample \example \addindex \example Indicates that a comment block contains documentation for a source code example. The name of the source file is \. The text of this file will be included in the documentation, just after the documentation contained in the comment block. All examples are placed in a list. The source code is scanned for documented members and classes. If any are found, the names are cross-referenced with the documentation. Source files or directories can be specified using the \ref cfg_example_path "EXAMPLE_PATH" tag of doxygen's configuration file. If \ itself is not unique for the set of example files specified by the \ref cfg_example_path "EXAMPLE_PATH" tag, you can include part of the absolute path to disambiguate it. If more that one source file is needed for the example, the \\include command can be used. \par Example: \verbinclude example.cpp Where the example file \c example_test.cpp looks as follows: \verbinclude example_test.cpp \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly \sa section \ref cmdinclude "\\include".
\subsection cmdfile \file [] \addindex \file Indicates that a comment block contains documentation for a source or header file with name \. The file name may include (part of) the path if the file-name alone is not unique. If the file name is omitted (i.e. the line after \\file is left blank) then the documentation block that contains the \\file command will belong to the file it is located in. \par Important: The documentation of global functions, variables, typedefs, and enums will only be included in the output if the file they are in is documented as well. \par Example: \verbinclude file.h \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\subsection cmdfn \fn (function declaration) \addindex \fn Indicates that a comment block contains documentation for a function (either global or as a member of a class). This command is needed if a comment block is \e not placed in front of the function declaration or definition. If your comment block \e is in front of the function declaration or definition this command can (and to avoid redundancy should) be ommitted. A full function declaration should be specified after the \\fn command. The argument ends at the end of the line. \par Example: \verbinclude func.h \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly \sa section \ref cmdvar "\\var" and \ref cmdtypedef "\\typedef".
\subsection cmdhideinitializer \hideinitializer \addindex \hideinitializer By default the value of a define and the initializer of a variable are displayed unless they are longer than 30 lines. By putting this command in a comment block of a define or variable, the initializer is always hidden. \sa section \ref cmdshowinitializer "\\showinitializer".
\subsection cmdingroup \ingroup ( [ ]) \addindex \ingroup If the \\ingroup command is placed in a comment block of a class, file or namespace, then it will be added to the group or groups identified by \. \sa page \ref grouping "Grouping", sections \ref cmddefgroup "\\defgroup", \ref cmdaddtogroup "\\addtogroup" and \ref cmdweakgroup "\\weakgroup"
\subsection cmdinterface \interface \addindex \interface Indicates that a comment block contains documentation for an interface with name \. The arguments are equal to the \\class command. \sa section \ref cmdclass "\\class".
\subsection cmdinternal \internal \addindex \internal This command writes the message `For internal use only' to the output. All text after a \c \internal command is ignored.
\subsection cmdmainpage \mainpage [(title)] \addindex \mainpage If the \\mainpage command is placed in a comment block the block is used to customize the index page (in HTML) or the first chapter (in \f$\mbox{\LaTeX}\f$). The title argument is optional and replaces the default title that doxygen normally generates. Here is an example: \verbatim /*! \mainpage My Personal Index Page * * \section intro Introduction * * This is the introduction. * * \section install Installation * * \subsection step1 Step 1: Opening the box * * etc... */ \endverbatim \sa section \ref cmdsection "\\section", section \ref cmdsubsection "\\subsection" and section \ref cmdpage "\\page".
\subsection cmdname \name (header) This command turns a comment block into a header definition of a member group. The comment block should be followed by a //@{ ... //@} block containing the members of the group. See section \ref memgroup for an example.
\subsection cmdnamespace \namespace \addindex \namespace Indicates that a comment block contains documentation for a namespace with name \.
\subsection cmdnosubgrouping \nosubgrouping This command can be put in the documentation of a class. It can be used in combination with member grouping to avoid that doxygen puts a member group as a subgroup of a Public/Protected/Private/... section.
\subsection cmdoverload \overload [(function declaration)] \addindex \overload This command can be used to generate the following standard text for an overloaded member function: `This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.' If the documentation for the overloaded member function is not located in front of the function declaration or definition, the optional argument should be used to specify the correct function. Any other documentation that is inside the documentation block will by appended after the generated message. \par Note 1: You are responsible that there is indeed an earlier documented member that is overloaded by this one. To prevent that document reorders the documentation you should set \ref cfg_sort_member_docs "SORT_MEMBER_DOCS" to NO in this case. \par Note 2: The \\overload command does not work inside a one-line comment. \par Example: \verbinclude examples/overload.cpp \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\subsection cmdpage \page (title) \addindex \page Indicates that a comment block contains a piece of documentation that is not directly related to one specific class, file or member. The HTML generator creates a page containing the documentation. The \f$\mbox{\LaTeX}\f$ generator starts a new section in the chapter `Page documentation'. \par Example: \verbinclude page.doc \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly \par Note: The \ argument consists of a combination of letters and number digits. If you wish to use upper case letters (e.g. \c MYPAGE1), or mixed case letters (e.g. \c MyPage1) in the \ argument, you should set \c CASE_SENSE_NAMES to \c YES. However, this is advisable only if your file system is case sensitive. Otherwise (and for better portability) you should use all lower case letters (e.g. \c mypage1) for \ in all references to the page. \sa section \ref cmdsection "\\section", section \ref cmdsubsection "\\subsection", and section \ref cmdref "\\ref".
\subsection cmdrelates \relates \addindex \relates This command can be used in the documentation of a non-member function \. It puts the function inside the `related function' section of the class documentation. This command is useful for documenting non-friend functions that are nevertheless strongly coupled to a certain class. It prevents the need of having to document a file, but only works for functions. \par Example: \verbinclude relates.cpp \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly
\subsection cmdshowinitializer \showinitializer \addindex \showinitializer By default the value of a define and the initializer of a variable are only displayed if they are less than 30 lines long. By putting this command in a comment block of a define or variable, the initializer is shown unconditionally. \sa section \ref cmdhideinitializer "\\hideinitializer".
\subsection cmdstruct \struct [] [] \addindex \struct Indicates that a comment block contains documentation for a struct with name \. The arguments are equal to the \\class command. \sa section \ref cmdclass "\\class".
\subsection cmdtypedef \typedef (typedef declaration) \addindex \typedef Indicates that a comment block contains documentation for a typedef (either global or as a member of a class). This command is equivalent to \\var and \\fn. \sa section \ref cmdfn "\\fn" and \ref cmdvar "\\var".
\subsection cmdunion \union [] [] \addindex \union Indicates that a comment block contains documentation for a union with name \. The arguments are equal to the \\class command. \sa section \ref cmdclass "\\class".
\subsection cmdvar \var (variable declaration) \addindex \var Indicates that a comment block contains documentation for a variable or enum value (either global or as a member of a class). This command is equivalent to \\typedef and \\fn. \sa section \ref cmdfn "\\fn" and \ref cmdtypedef "\\typedef".
\subsection cmdweakgroup \weakgroup [(title)] \addindex \addtogroup Can be used exactly like \ref cmdaddtogroup "\\addtogroup", but has a lower priority when it comes to resolving conflicting grouping definitions. \sa page \ref grouping "Grouping" and \ref cmdaddtogroup "\\addtogroup".

\subsection cmdaddindex \addindex (text) \addindex \addindex This command adds (text) to the \f$\mbox{\LaTeX}\f$ index.
\subsection cmdanchor \anchor \addindex \anchor This command places an invisible, named anchor into the documentation to which you can refer with the \\ref command. \sa section \ref cmdref "\\ref".
\subsection cmdendlink \endlink \addindex \endlink This command ends a link that is started with the \\link command. \sa section \ref cmdlink "\\link".
\subsection cmdlink \link \addindex \link The links that are automatically generated by doxygen always have the name of the object they point to as link-text. The \\link command can be used to create a link to an object (a file, class, or member) with a user specified link-text. The link command should end with an \\endlink command. All text between the \\link and \\endlink commands serves as text for a link to the \ specified as the first argument of \\link. See section \ref autolink "autolink" for more information on automatically generated links and valid link-objects.
\subsection cmdref \ref ["(text)"] \addindex \ref Creates a reference to a named section, subsection, page or anchor. For HTML documentation the reference command will generate a link to the section. For a sections or subsections the title of the section will be used as the text of the link. For anchor the optional text between quotes will be used or \ if no text is specified. For \f$\mbox{\LaTeX}\f$ documentation the reference command will generate a section number for sections or the text followed by a page number if \ refers to an anchor. \sa Section \ref cmdpage "\\page" for an example of the \\ref command.
\subsection cmdsection \section (section title) \addindex \section Creates a section with name \. The title of the section should be specified as the second argument of the \\section command. \warning This command only works inside related page documentation and \e not in other documentation blocks! \sa Section \ref cmdpage "\\page" for an example of the \ref cmdsection "\\section" command.
\subsection cmdsubsection \subsection (subsection title) \addindex \subsection Creates a subsection with name \. The title of the subsection should be specified as the second argument of the \\subsection command. \warning This command only works inside related page documentation and \e not in other documentation blocks! \sa Section \ref cmdpage "\\page" for an example of the \ref cmdsubsection "\\cmdsubsection" command.

\subsection cmddontinclude \dontinclude \addindex \dontinclude This command can be used to parse a source file without actually verbatim including it in the documentation (as the \\include command does). This is useful if you want to divide the source file into smaller pieces and add documentation between the pieces. Source files or directories can be specified using the \ref cfg_example_path "EXAMPLE_PATH" tag of doxygen's configuration file. The class and member declarations and definitions inside the code fragment are `remembered' during the parsing of the comment block that contained the \\dontinclude command. For line by line descriptions of source files, one or more lines of the example can be displayed using the \\line, \\skip, \\skipline, and \\until commands. An internal pointer is used for these commands. The \\dontinclude command sets the pointer to the first line of the example. \par Example: \verbinclude include.cpp Where the example file \c example_test.cpp looks as follows: \verbinclude example_test.cpp \htmlonly Click here for the corresponding HTML documentation that is generated by doxygen. \endhtmlonly \sa sections \ref cmdline "\\line", \ref cmdskip "\\skip", \ref cmdskipline "\\skipline", and \ref cmduntil "\\until".
\subsection cmdinclude \include \addindex \include This command can be used to include a source file as a block of code. The command takes the name of an include file as an argument. Source files or directories can be specified using the \ref cfg_example_path "EXAMPLE_PATH" tag of doxygen's configuration file. If \ itself is not unique for the set of example files specified by the \ref cfg_example_path "EXAMPLE_PATH" tag, you can include part of the absolute path to disambiguate it. Using the \\include command is equivalent to inserting the file into the documentation block and surrounding it with \ref cmdcode "\\code" and \ref cmdendcode "\\endcode" commands. The main purpose of the \\include command is to avoid code duplication in case of example blocks that consist of multiple source and header files. For a line by line description of a source files use the \ref cmddontinclude "\\dontinclude" command in combination with the \ref cmdline "\\line", \ref cmdskip "\\skip", \ref cmdskipline "\\skipline", and \\until commands. \sa section \ref cmdexample "\\example" and \ref cmddontinclude "\\dontinclude".
\subsection cmdline \line ( pattern ) \addindex \line This command searches line by line through the example that was last included using \\include or \\dontinclude until it finds a non-blank line. If that line contains the specified pattern, it is written to the output. The internal pointer that is used to keep track of the current line in the example, is set to the start of the line following the non-blank line that was found (or to the end of the example if no such line could be found). See section \ref cmddontinclude "\\dontinclude" for an example.
\subsection cmdskip \skip ( pattern ) \addindex \skip This command searches line by line through the example that was last included using \\include or \\dontinclude until it finds a line that contains the specified pattern. The internal pointer that is used to keep track of the current line in the example, is set to the start of the line that contains the specified pattern (or to the end of the example if the pattern could not be found). See section \ref cmddontinclude "\\dontinclude" for an example.
\subsection cmdskipline \skipline ( pattern ) \addindex \skipline This command searches line by line through the example that was last included using \\include or \\dontinclude until it finds a line that contains the specified pattern. It then writes the line to the output. The internal pointer that is used to keep track of the current line in the example, is set to the start of the line following the line that is written (or to the end of the example if the pattern could not be found). \par Note: The command: \verbatim\skipline pattern\endverbatim is equivalent to: \verbatim \skip pattern \line pattern\endverbatim See section \ref cmddontinclude "\\dontinclude" for an example.
\subsection cmduntil \until ( pattern ) \addindex \until This command writes all lines of the example that was last included using \\include or \\dontinclude to the output, until it finds a line containing the specified pattern. The line containing the pattern will be written as well. The internal pointer that is used to keep track of the current line in the example, is set to the start of the line following last written line (or to the end of the example if the pattern could not be found). See section \ref cmddontinclude "\\dontinclude" for an example.
\subsection cmdverbinclude \verbinclude \addindex \verbinclude This command includes the file \ verbatim in the documentation. The command is equivalent to pasting the file in the documentation and placing \\verbatim and \\endverbatim commands around it. Files or directories that doxygen should look for can be specified using the \ref cfg_example_path "EXAMPLE_PATH" tag of doxygen's configuration file.
\subsection cmdhtmlinclude \htmlinclude \addindex \htmlinclude This command includes the file \ as is in the HTML documentation. The command is equivalent to pasting the file in the documentation and placing \\htmlonly and \\endhtmlonly commands around it. Files or directories that doxygen should look for can be specified using the \ref cfg_example_path "EXAMPLE_PATH" tag of doxygen's configuration file.

\subsection cmda \a \addindex \a Displays the argument \ using a special font. Use this command to refer to member arguments in the running text. \par Example: \verbatim ... the \a x and \a y coordinates are used to ... \endverbatim This will result in the following text:

... the \a x and \a y coordinates are used to ...
\subsection cmdarg \arg { item-description } \addindex \arg This command has one argument that continues until the first blank line or until another \\arg is encountered. The command can be used to generate a simple, not nested list of arguments. Each argument should start with a \\arg command. \par Example: Typing: \verbatim \arg \c AlignLeft left alignment. \arg \c AlignCenter center alignment. \arg \c AlignRight right alignment No other types of alignment are supported. \endverbatim will result in the following text:

  • \c AlignLeft left alignment.
  • \c AlignCenter center alignment.
  • \c AlignRight right alignment

No other types of alignment are supported. \par Note: For nested lists, HTML commands should be used. Equivalent to \ref cmdli "\\li"
\subsection cmdb \b \addindex \b Displays the argument \ using a bold font. Equivalent to \word\.
\subsection cmdc \c \addindex \c Displays the argument \ using a typewriter font. Use this to refer to a word of code. Equivalent to \word\. \par Example: Typing: \verbatim ... This function returns \c void and not \c int ... \endverbatim will result in the following text:

... This function returns \c void and not \c int ... Equivalent to \ref cmdp "\\p"
\subsection cmdcode \code \addindex \code Starts a block of code. A code block is treated differently from ordinary text. It is interpreted as C/C++ code. The names of the classes and members that are documented are automatically replaced by links to the documentation. \sa section \ref cmdendcode "\\endcode", section \ref cmdverbatim "\\verbatim"
\subsection cmde \e \addindex \e Displays the argument \ in italics. Use this command to emphasize words. \par Example: Typing: \verbatim ... this is a \e really good example ... \endverbatim will result in the following text:

... this is a \e really good example ... Equivalent to \ref cmdem "\\em"
\subsection cmdem \em \addindex \e Displays the argument \ in italics. Use this command to emphasize words. \par Example: Typing: \verbatim ... this is a \em really good example ... \endverbatim will result in the following text:

... this is a \em really good example ... Equivalent to \ref cmde "\\e"
\subsection cmdendcode \endcode \addindex \endcode Ends a block of code. \sa section \ref cmdcode "\\code"
\subsection cmdendhtmlonly \endhtmlonly \addindex \endhtmlonly Ends a block of text that was started with a \\htmlonly command. \sa section \ref cmdhtmlonly "\\htmlonly".
\subsection cmdendlatexonly \endlatexonly \addindex \endlatexonly Ends a block of text that was started with a \\latexonly command. \sa section \ref cmdlatexonly "\\latexonly".
\subsection cmdendverbatim \endverbatim \addindex \endverbatim Ends a block of text that was started with a \\verbatim command. \sa section \ref cmdverbatim "\\verbatim".
\subsection cmdfdollar \f$ \addindex \f$ Marks the start and end of an in-text formula. \sa section \ref formulas "formulas" for an example.
\subsection cmdfbropen \f[ \addindex \f[ Marks the start of a long formula that is displayed centered on a separate line. \sa section \ref cmdfbrclose "\\f]" and section \ref formulas "formulas".
\subsection cmdfbrclose \f] \addindex \f] Marks the end of a long formula that is displayed centered on a separate line. \sa section \ref cmdfbropen ""\\f[" and section \ref formulas "formulas".
\subsection cmdhtmlonly \htmlonly \addindex \htmlonly Starts a block of text that will be verbatim included in the generated HTML documentation only. The block ends with a endhtmlonly command. This command can be used to include HTML code that is too complex for doxygen (i.e. applets, java-scripts, and HTML tags that require attributes). You can use the \\latexonly and \\endlatexonly pair to provide a proper \f$\mbox{\LaTeX}\f$ alternative. \b Note: environment variables (like \$(HOME) ) are resolved inside a HTML-only block. \sa section \ref cmdhtmlonly "\\htmlonly" and section \ref cmdlatexonly "\\latexonly".
\subsection cmdimage \image [""] [=] \addindex \image Inserts an image into the documentation. This command is format specific, so if you want to insert an image for more than one format you'll have to repeat this command for each format. The first argument specifies the output format. Currently, the following values are supported: \c html and \c latex. The second argument specifies the file name of the image. doxygen will look for files in the paths (or files) that you specified after the \ref cfg_image_path "IMAGE_PATH" tag. If the image is found it will be copied to the correct output directory. If the image name contains spaces you'll have to put quotes (") around it. You can also specify an absolute URL instead of a file name, but then doxygen does not copy the image nor check its existance. The third argument is optional and can be used to specify the caption that is displayed below the image. This argument has to be specified between quotes even if it does not contain any spaces. The quotes are stripped before the caption is displayed. The fourth argument is also optional and can be used to specify the width or height of the image. This is only useful for \f$\mbox{\LaTeX}\f$ output (i.e. format=latex). The \c sizeindication can be either \c width or \c height. The size should be a valid size specifier in \f$\mbox{\LaTeX}\f$ (for example 10cm or 6in or a symbolic width like \\textwidth). Here is example of a comment block: \verbatim /*! Here is a snapshot of my new application: * \image html application.jpg * \image latex application.eps "My application" width=10cm */ \endverbatim And this is an example of how the relevant part of the configuration file may look: \verbatim IMAGE_PATH = my_image_dir \endverbatim \warning The image format for HTML is limited to what your browser supports. For \f$\mbox{\LaTeX}\f$ the image format must be Encapsulated PostScript (eps).

Doxygen does not check if the image is in the correct format. So \e you have to make sure this is the case!
\subsection cmdlatexonly \latexonly \addindex \latexonly Starts a block of text that will be verbatim included in the generated \f$\mbox{\LaTeX}\f$ documentation only. The block ends with a endlatexonly command. This command can be used to include \f$\mbox{\LaTeX}\f$ code that is too complex for doxygen (i.e. images, formulas, special characters). You can use the \\htmlonly and \\endhtmlonly pair to provide a proper HTML alternative. \b Note: environment variables (like \$(HOME) ) are resolved inside a \f$\mbox{\LaTeX}\f$-only block. \sa section \ref cmdlatexonly "\\latexonly" and section \ref cmdhtmlonly "\\htmlonly".
\subsection cmdli \li { item-description } \addindex \li This command has one argument that continues until the first blank line or until another \\li is encountered. The command can be used to generate a simple, not nested list of arguments. Each argument should start with a \\li command. \par Example: Typing: \verbatim \li \c AlignLeft left alignment. \li \c AlignCenter center alignment. \li \c AlignRight right alignment No other types of alignment are supported. \endverbatim will result in the following text:

  • \c AlignLeft left alignment.
  • \c AlignCenter center alignment.
  • \c AlignRight right alignment

No other types of alignment are supported. \par Note: For nested lists, HTML commands should be used. Equivalent to \ref cmdarg "\\arg"
\subsection cmdp \p \addindex \p Displays the parameter \ using a typewriter font. You can use this command to refer to member function parameters in the running text. \par Example: \verbatim ... the \p x and \p y coordinates are used to ... \endverbatim This will result in the following text:

... the \p x and \p y coordinates are used to ... Equivalent to \ref cmdc "\\c"
\subsection cmdverbatim \verbatim \addindex \verbatim Starts a block of text that will be verbatim included in both the HTML and the \f$\mbox{\LaTeX}\f$ documentation. The block should end with a \\endverbatim block. All commands are disabled in a verbatim block. \warning Make sure you include a \\endverbatim command for each \\verbatim command or the parser will get confused!
\subsection cmdbackslash \\ \addindex \\ This command writes a backslash character (\\) to the HTML and \f$\mbox{\LaTeX}\f$ output. The backslash has to be escaped in some cases because doxygen uses it to detect commands.
\subsection cmdat \@ \addindex \@ This command writes an at-sign (@) to the HTML and \f$\mbox{\LaTeX}\f$ output. The at-sign has to be escaped in some cases because doxygen uses it to detect JavaDoc commands.
\subsection cmdamp \& \addindex \& This command writes the \& character to the HTML and \f$\mbox{\LaTeX}\f$ output. This character has to be escaped because it has a special meaning in HTML.
\subsection cmddollar \$ \addindex \$ This command writes the \$ character to the HTML and \f$\mbox{\LaTeX}\f$ output. This character has to be escaped in some cases, because it is used to expand environment variables.
\subsection cmdhash \# \addindex \# This command writes the \# character to the HTML and \f$\mbox{\LaTeX}\f$ output. This character has to be escaped in some cases, because it is used to refer to documented entities.
\subsection cmdlt \\< \addindex \\< This command writes the \< character to the HTML and \f$\mbox{\LaTeX}\f$ output. This character has to be escaped because it has a special meaning in HTML.
\subsection cmdgt \\> \addindex \\> This command writes the \> character to the HTML and \f$\mbox{\LaTeX}\f$ output. This character has to be escaped because it has a special meaning in HTML.
