+/**
+Declares a class as being non-sharable.
+
+If a class is non-sharable, then a class implemented in another DLL cannot
+derive (inherit) from that class.
+
+Declaring a class as non-sharable prevents the compiler from exporting compiler
+implementation-specific symbols, i.e. run-time type-information and virtual
+tables. This prevents classes in other DLLs from being able to derive from it.
+
+Note :
+- if a class is marked as non-sharable, then Symbian OS requires all
+classes that are derived from that class, and which are also implemented in the same DLL, 
+to be declared as non-sharable.
+- by default, a class is sharable.
+
+The following code fragment shows how a non-sharable class is declared.
+@code
+NONSHARABLE_CLASS(CMyClass) : public CBase
+	{
+	public :
+	...
+	private :
+	...
+	}
+@endcode
+
+@param x  The name of the class to be declared as non-sharable.
