+ \rst
+ A dynamically growing memory buffer for trivially copyable/constructible types
+ with the first ``SIZE`` elements stored in the object itself.
+
+ You can use one of the following type aliases for common character types:
+
+ +----------------+------------------------------+
+ | Type | Definition |
+ +================+==============================+
+ | memory_buffer | basic_memory_buffer<char> |
+ +----------------+------------------------------+
+ | wmemory_buffer | basic_memory_buffer<wchar_t> |
+ +----------------+------------------------------+
+
+ **Example**::
+
+ fmt::memory_buffer out;
+ format_to(out, "The answer is {}.", 42);
+
+ This will append the following output to the ``out`` object:
+
+ .. code-block:: none
+
+ The answer is 42.
+
+ The output can be converted to an ``std::string`` with ``to_string(out)``.

+// 1. <log_name> should be replaced with your log name (e.g. your application name)
+// 2. <source_name> should be replaced with the specific source name and the key should be duplicated for
+// each source used in the application
+//
+// Since typically modifications of this kind require elevation, it's better to do it as a part of setup procedure.
+// The snippet below uses mscoree.dll as the message file as it exists on most of the Windows systems anyway and

+// You can also specify a custom message file if needed.
