+/** Class to declare a service implementation.  There is no need to implement
+    lang::XServiceInfo nor lang::XInitialization anymore.
+    The declaration can be done in various ways, the (simplest) form is
+
+    <pre>
+    class MyClass : public cppu::WeakImplHelper<XInterface1, XInterface2> {
+    public:
+        MyClass( uno::Reference<uno::XComponentContext> const& xContext )
+        [...]
+    };
+    [...]
+    namespace sdecl = comphelper::service_decl;
+    sdecl::ServiceDecl const myDecl(
+        sdecl::class_<MyClass>(),
+        "my.unique.implementation.name",
+        "MyServiceSpec1;MyServiceSpec2" );
+    </pre>
+
+    If the service demands initialization by arguments, the implementation
+    class has to define a constructor taking both arguments and component
+    context:
+
+    <pre>
+    class MyClass : public cppu::WeakImplHelper<XInterface1, XInterface2> {
+    public:
+        MyClass( uno::Sequence<uno::Any> const& args,
+                 uno::Reference<uno:XComponentContext> const& xContext )
+        [...]
+    };
+    [...]
+    namespace sdecl = comphelper::service_decl;
+    sdecl::ServiceDecl const myDecl(
+        sdecl::class_<MyClass, sdecl::with_args<true> >(),
+        "my.unique.implementation.name",
+        "MyServiceSpec1;MyServiceSpec2" );
+    </pre>
+
+    Additionally, there is the possibility to process some code after creation,
+    e.g. to add the newly created object as a listener or perform aggregation
+    (C++-UNO only):
+
+    <pre>
+    uno::Reference<uno::XInterface> somePostProcCode( MyClass * p );
+    [...]
+    namespace sdecl = comphelper::service_decl;
+    sdecl::ServiceDecl const myDecl(
+        sdecl::class_<MyClass, ... >(&somePostProcCode),
+        "my.unique.implementation.name",
+        "MyServiceSpec1;MyServiceSpec2" );
+    </pre>
+
+    In the latter case, somePostProcCode gets the yet unacquired "raw" pointer.
