- * <c>[token]</c> means either <c>token</c> or nothing (i.e.\, <c>token</c> is

- * On C99 and later compilers that support variadic macros\, the above

- * on C++ compilers that support variadic macros so it should be used with

+@brief This macro is used to start a local function declaration.
+
+This macro must be used within a declarative context, it must follow the local
+function result type, it must be followed by the local function body code, and
+then by the @RefMacro{BOOST_LOCAL_FUNCTION_NAME} macro (see the
+@RefSect{Tutorial} and @RefSectId{Advanced_Topics, Advanced Topics} sections):
+@code
+{ // Some declarative context.
+ ...
+ result_type BOOST_LOCAL_FUNCTION(declarations) {
+ ... // Body code.
+ } BOOST_LOCAL_FUNCTION_NAME(qualified_function_name)
+ ...
+}
+@endcode
+
+As usual, exceptions specifications can be optionally programmed just after the
+macro and before the body code block <c>{ ... }</c> (but the exception
+specifications will only apply to the body code and not to the library code
+automatically generated by the macro expansion, see the
+@RefSectId{Advanced_Topics, Advanced Topics} section).
+
+Within templates, the special macro @RefMacro{BOOST_LOCAL_FUNCTION_TPL} must be
+used instead of_at_RefMacro{BOOST_LOCAL_FUNCTION}.
+
+@Params
+@Param{declarations,
+On compilers that support variadic macros\, the parameter declarations are
+defined by the following grammar:
+@code
+ declarations:
+ void | declaration_tuple | declaration_sequence
+ declaration_tuple:
+ declaration\, declaration\, ...
+ declaration_sequence:
+ (declaration) (declaration) ...
+ declaration:
+ bound_variable | parameter | default_value | result_type
+ bound_variable:
+ [const] bind [(variable_type)] [&] variable_name
+ parameter:
+ [auto | register] parameter_type parameter_name
+ default_value:
+ default parameter_default_value
+ result_type:
+ return function_result_type
+@endcode
+On compilers that do not support variadic macros\, <c>declaration_tuple</c>
+cannot be used:
+@code
+ declarations:
+ void | declaration_sequence
+@endcode
+
+(Lexical conventions: <c>token1 | token2</c> means either <c>token1</c> or
+<c>token2</c>; <c>[token]</c> means either <c>token</c> or nothing;
+<c>{expression}</c> means the token resulting from the expression.)
+}
+@EndParams
+
+Note that on compilers that support variadic macros, commas can be used to
+separate the declarations resembling more closely the usual C++ function
+declaration syntax.
+This is the preferred syntax.
+However, for portability, on all C++ compilers (with and without variadic
+macros) the same library macros also accept parameter declarations specified as
+a Boost.Preprocessor sequence separated by round parenthesis <c>()</c>.
+
+When binding the object <c>this</c>, the special symbol <c>this_</c> needs to
+be used instead of <c>this</c> as the name of the variable to bind and also
+within the local function body to access the object.
+(Mistakenly using <c>this</c> instead of <c>this_</c> might not always result in a compiler error and will in general lead to undefined behaviour.)
+
+The result type must either be specified just before the macro or within the
+macro declarations prefixed by <c>return</c> (but not in both places).
+
+The maximum number of local function parameters (excluding bound variables) is
+specified by the configuration macro
+@RefMacro{BOOST_LOCAL_FUNCTION_CONFIG_ARITY_MAX}.
+The maximum number of bound variables is specified by the configuration macro
+@RefMacro{BOOST_LOCAL_FUNCTION_CONFIG_BIND_MAX}.
+
+@Note Local functions are functors so they can be assigned to other functors
+like <c>boost::function</c> (see Boost.Function).
+
+@Note This macro cannot be used multiple times on the same line (because it
+internally uses the line number <c>__LINE__</c> to generate unique
+identifiers).

+@brief This macro is used to start a local function declaration within templates.

+@brief This macro expands to the type of the specified bound variable.

+
+@Params
+@Param{bound_variable_name,
+The name of one of the local function's bound variables.

+
+For example, if a variable named <c>t</c> of type <c>T</c> is:
+@li Bound by value using <c>bind t</c> then

+
+This macro can be used within the local functions body to refer to the bound

+Programmers can simply instruct the C++ compiler where to find the library header files (`-I` option for GCC, `/I` option for MSVC, etc) and they can start compiling code using this library.
 
 This library implementation uses a number of __Boost__ libraries among which: __Boost_Preprocessor__, __Boost_ScopeExit__, __Boost_Typeof__, __Boost_TypeTraits__, and __Boost_MPL__.
 These __Boost__ libraries must be properly installed on your system in order for this library to work.

 *Rationale.*
 This library concatenates symbols specified by the programmers (e.g., the local function name) with other symbols (e.g., special prefixes or preprocessor line numbers) to make internal symbols with unique names to avoid name clashes.
-These symbols are separated by the letter "`X`" when they are concatenated so they read more easily during debugging.
-The underscore character "`_`" could not be used instead of the letter "`X`" because if the original symbols already contained a leading or trailing underscore, the concatenation could result in a symbol with double underscores "`__`" which is reserved by the C++ standard.

-[section Compile-Time Configuration]
+[section Configuration]
 
 Some of the library behaviour can be changed at compile-time by defining special /configuration macros/.
 If a configuration macro is left undefined, the library will use an appropriate default value for it.
 
-All configuration macros have names prefixed by `BOOST_LOCAL_CONFIG_...` (see the __Reference__ section).
+All configuration macros are defined in the header file [headerref boost/local_function/config.hpp].
 It is strongly recommended not to change the library configuration macro definitions unless strictly necessary.

- The run-time performances of this library local functions are explained

- This run-time performance cost on C++03

- requirements of specific applications. For example, an application might

 The casting functor trick measured slightly better run-time performances than the virtual functor trick so the current implementation of this library uses the casting functor trick (probably because in addition to the indirect function call, the virtual functor trick also requires accessing the [@http://en.wikipedia.org/wiki/Virtual_method_table virtual function table]).
-However, neither one of tricks has been observed to allow for compiler optimizations that inline the local function calls because they rely on one indirect function call (via either a function pointer or a virtual function respectively).

 Therefore, on compilers that accept local types as template parameters (MSVC, __CPP11__, etc, see __N2657__), this library automatically generates code that passes the local class type directly as template parameter without using neither one of these two tricks in order to take full advantage of compiler optimizations that inline the local function calls.

-Programmers are responsible to make sure that `this` is never used within a local function body which should only use the special symbol `this_`.
+This is possible because of C++ defect fix #46 that made inner and local types able to access all outer class members regardless of their access level.

-For example, let's program a local function `add` similar to the one in the example from the __Introduction__ section but using a member function to illustrate how to bind the object `this` (see also [@../../test/add_this.cpp `"add_this.cpp"`]):
