/*! \page autolink Automatic link generation

  Most documentation systems have special `see also' sections where links

  to other pieces of documentation can be inserted.

  Although doxygen also has a command to start such a section (See section

  \ref cmdsa "\\sa"), it does allow you to put these kind of links anywhere in the

  documentation. 

  For \f$\mbox{\LaTeX}\f$ documentation a reference to the page number

  is written instead of a link. Furthermore, the index at the end of the 

  document can be used to quickly find the documentation of a member, class, 

  namespace or file.

  For man pages no reference information is generated.

  The next sections show how to generate links to the various documented 

  entities in a source file.

  \section linkurl Links to web pages and mail addresses

  Doxygen will automatically replace any URLs and mail addresses found in the

  documentation by links (in HTML).

  \section linkclass Links to classes.

  All words in the documentation that correspond to a documented class and

  contain at least one non-lower case character will automatically be 

  replaced by a link to the page containing the 

  documentation of the class. If you want to prevent that a word 

  that corresponds to a documented class is replaced by a link you

  should put a \% in front of the word.

  To link to an all lower case symbol, use \ref cmdref "\\ref".

  \section linkfile Links to files.

  All words that contain a dot (<tt>.</tt>) that is not the last character

  in the word are considered to be file names.

  If the word is indeed the name of a documented input file, a link will 

  automatically be created to the documentation of that file.

  \section linkfunc Links to functions.

  Links to functions are created if one of the following patterns is 

  encountered:

  <ol>

  <li><tt>\<functionName\>"("\<argument-list\>")"</tt>

  <li><tt>\<functionName\>"()"</tt>

  <li><tt>"::"\<functionName\></tt>

  <li><tt>(\<className\>"::")<sup>n</sup>\<functionName\>"("\<argument-list\>")"</tt>

  <li><tt>(\<className\>"::")<sup>n</sup>\<functionName\>"("\<argument-list\>")"\<modifiers\></tt>

  <li><tt>(\<className\>"::")<sup>n</sup>\<functionName\>"()"</tt>

  <li><tt>(\<className\>"::")<sup>n</sup>\<functionName\></tt>

  </ol>

  where n\>0. 

  \par Note 1: 

    Function arguments should be specified with correct types, i.e. 

    'fun(const std::string&,bool)' or '()' to match any prototype.

  \par Note 2:

    Member function modifiers (like 'const' and 'volatile') 

    are required to identify the target, i.e. 'func(int) const' and 'fun(int)'

    target different member functions.

  \par Note 3: 

    For JavaDoc compatibility a \# may be used instead of a :: in 

    the patterns above.

  \par Note 4:

    In the documentation of a class containing a member foo, 

    a reference to a global variable is made using ::foo, whereas \#foo

    will link to the member.

  For non overloaded members the argument list may be omitted.

  If a function is overloaded and no matching argument list is specified

  (i.e. pattern 2 or 6 is used), a link will be created to the 

  documentation of one of the overloaded members.

  For member functions the class scope (as used in patterns 4 to 7) may

  be omitted, if:

  <ol>

  <li>The pattern points to a documented member that belongs to the same class

      as the documentation block that contains the pattern. 

  <li>The class that corresponds to the documentation blocks that contains

      the pattern has a base class that contains a documented member

      that matches the pattern.

  </ol>

  \section linkother Links to variables, typedefs, enum types, enum values and defines.

  All of these entities can be linked to in the same way as described in the 

  previous section. For sake of clarity it is advised to only use 

  patterns 3 and 7 in this case.

  \par Example:

  \verbinclude autolink.cpp

  \htmlonly

  Click <a href="$(DOXYGEN_DOCDIR)/examples/autolink/html/index.html">here</a> 

  for the corresponding HTML documentation that is generated by Doxygen.

  \endhtmlonly

  \section resolving typedefs.

  Typedefs that involve classes, structs and unions, like

\verbatim

typedef struct StructName TypeName

\endverbatim

  create an alias for StructName, so links will be generated to StructName, 

  when either StructName itself or TypeName is encountered.

  \par Example:

  \verbinclude restypedef.cpp

  \htmlonly

  Click <a href="$(DOXYGEN_DOCDIR)/examples/restypedef/html/restypedef_8cpp.html">here</a> 

  for the corresponding HTML documentation that is generated by Doxygen.

  \endhtmlonly
