+/// \class sf::NonCopyable
+/// \ingroup system
+///
+/// This class makes its instances non-copyable, by explicitly
+/// disabling its copy constructor and its assignment operator.
+///
+/// To create a non-copyable class, simply inherit from
+/// sf::NonCopyable.
+///
+/// The type of inheritance (public or private) doesn't matter,
+/// the copy constructor and assignment operator are declared private
+/// in sf::NonCopyable so they will end up being inaccessible in both
+/// cases. Thus you can use a shorter syntax for inheriting from it
+/// (see below).
+///
+/// Usage example:
+/// \code
+/// class MyNonCopyableClass : sf::NonCopyable
+/// {
+///     ...
+/// };
+/// \endcode
+///
+/// Deciding whether the instances of a class can be copied
+/// or not is a very important design choice. You are strongly
+/// encouraged to think about it before writing a class,
+/// and to use sf::NonCopyable when necessary to prevent
+/// many potential future errors when using it. This is also
+/// a very important indication to users of your class.
