+// Implementation of the move_ptr from the "Move Proposal" 
+// (http://std.dkuug.dk/jtc1/sc22/wg21/docs/papers/2002/n1377.htm) 
+// enhanced to support custom deleters and safe boolean conversions.
+//
+// The implementation is based on an implementation by Daniel Wallin, at
+// "http://aspn.activestate.com/ASPN/Mail/Message/Attachments/boost/
+// 400DC271.1060903@student.umu.se/move_ptr.hpp". The current was adapted

+// Rani Sharoni.
