Greetings Boost: I have uploaded a new version having minor fixes but I have also included some basic documentation describing the shifted_ptr internals. The former API reference doc has moved to its given "api" subdirectory. I apologize for the non-standard format of the documentation files; this is temporary. There isn't much left to be done on the functionality side of the project besides adding pool allocation for internal objects. Let's put an end to that application crash era: http://www.boost-consulting.com/vault/index.php?action=downloadfile&filename=shifted_ptr.zip&directory=Memory Regards, -Phil
