+/// \class MemoryeInputStream
+/// \ingroup system
+///
+/// This class is a specialization of InputStream that
+/// reads from data in memory.
+///
+/// It wraps a memory chunk in the common InputStream interface
+/// and therefore allows to use generic classes or functions
+/// that accept such a stream, with content already loaded in memory.
+///
+/// In addition to the virtual functions inherited from
+/// InputStream, MemoryInputStream adds a function to
+/// specify the pointer and size of the data in memory.
+///
+/// SFML resource classes can usually be loaded directly from
+/// memory, so this class shouldn't be useful to you unless
+/// you create your own algorithms that operate on a InputStream.
+///
+/// Usage example:
+/// \code
+/// void process(InputStream& stream);
+///
+/// MemoryStream stream;
+/// stream.open(thePtr, theSize);
+/// process(stream);
+/// \endcode
+///
+/// InputStream, FileStream
