+/// \class sf::InputStream
+/// \ingroup system
+///
+/// This class allows users to define their own file input sources
+/// from which SFML can load resources.
+///
+/// SFML resource classes like sf::Texture and
+/// sf::SoundBuffer provide loadFromFile and loadFromMemory functions,
+/// which read data from conventional sources. However, if you
+/// have data coming from a different source (over a network,
+/// embedded, encrypted, compressed, etc) you can derive your
+/// own class from sf::InputStream and load SFML resources with
+/// their loadFromStream function.
+///
+/// Usage example:
+/// \code
+/// // custom stream class that reads from inside a zip file
+/// class ZipStream : public sf::InputStream
+/// {
+/// public:
+///
+///     ZipStream(std::string archive);
+///
+///     bool open(std::string filename);
+///
+///     Int64 read(void* data, Int64 size);
+///
+///     Int64 seek(Int64 position);
+///
+///     Int64 tell();
+///
+///     Int64 getSize();
+///
+/// private:
+///
+///     ...
+/// };
+///
+/// // now you can load textures...
+/// sf::Texture texture;
+/// ZipStream stream("resources.zip");
+/// stream.open("images/img.png");
+/// texture.loadFromStream(stream);
+///
+/// // musics...
+/// sf::Music music;
+/// ZipStream stream("resources.zip");
+/// stream.open("musics/msc.ogg");
+/// music.openFromStream(stream);
+///
+/// // etc.
+/// \endcode
