+The C++ standard library is your best friend. For example, 
+if you need to allocate some temporary variable on the heap,
+use an @code{auto_ptr<>} that does the right thing even when
+an exception is raised, and that respects 
+@acronym{RAII,Resource Acquisition Is Initialization}.
+
+Also using extensively algorithms like @code{for_each} and
+@code{copy} greatly helps.
+
+@item
+Use @code{glib::ustring} in place of @code{std::string} as 
+often as possible, to ensure Unicode support.
+
+@item
+If you need a smart pointer, be sure to check out 
+@code{glib::RefPtr<>}.
