+@brief Manipulators = Formatters and/or destinations.
+
+All formatters need to derive from a <b>common %base class</b>. Same goes for destinations.
+
+Remember:
+- formatter - allows formatting the message before writing it (like, prepending extra information - an index, the time, thread id, etc)
+- destination - is a place where the message is to be written to (like, the console, a file, a socket, etc)
+
+In your @ref boost::logging::writer::format_write "format_write" object, you can have several formatters and destinations. Note that each formatter class and each destination class is a @c %manipulator.
+
+
+
+When dealing with formatters, the first thing you must do is to specify that common %base class.
+All formatter classes will derive from it, directly or indirectly. Again, same goes for destinations.
+
+
+Note that the %formatter %base class and the %destination %base class don't need to be the same. Example:
+
+@code
+typedef optimize::cache_string_one_str<> cache_string;
+typedef formatter::base<cache_string&, op_equal::same_type > format_base;
+
+
+struct write_time : format_base {
+ void operator()(cache_string & str) const {
+ char t[10];
+ time_t now = time(0);
+ tm details = *localtime(&now);
+ strftime(t, 10, "%M:%S ", &details);
+ str.prepend_string(t);
+ }
+};
+//...
+
+typedef destination::base<const std::string &, op_equal::same_type> destination_base;
+struct write_to_cout : destination_base {
+ void operator()(param msg) const {
+ std::cout << msg ;
+ }
+};
+
+@endcode
+
+This namespace contains the classes formatter or destination classes need to use as %base class.
+
+
+
+@section manipulator_base Manipulator base classes
+
+Your formatter or destination class should derive from either of the following:
+- base - recommented %base class
+- base_no_operator_call - %base class , not implementing the operator() call
+
+
+
+
+@section share_data Sharing data for manipulator classes
+
+The manipulator classes need to contain data as constant:
+
+@code
+struct my_formatter : format_base {
+ ...
+private:
+ const int m_idx;
+};
+@endcode
+
+As long as data is constant, it's all ok - that is, no matter what functions get called, all the data in the formatter/destination
+must remain constant. We need constant functors - just like in STL - because internally, we copy formatters/destinations: that is, we keep
+several copies of a certain object - they all need to be syncronized. In case the objects' data is constant, that's no problem.
+
+In case the data needs to be changed - it needs to be shared. Several copies of the same instance must point to the same data. In other words,
+use shared pointers:
+
+@code
+struct write_to_file {
+ typedef boost::shared_ptr<std::ofstream> ptr;
+ write_to_file(const std::string & filename) : m_out(new std::ofstream(filename.c_str())) {}
+ void operator()(const std::string & msg) const {
+ (*m_out) << msg << std::endl ;
+ }
+ mutable ptr m_out;
+};
+@endcode
+
+Since quite a few of the manipulator objects will need this, it's quite acceptable to have a class that deals with this:
+the non_const_context class.
