[Boost-users] Status of smart_assert

Howdy, I was searching for an intelligent assert facility with serveral debug levels, that asserts when it is run debug mode and throws in release mode. That is how i ran into Boost's SMART_ASSERT ( http://www.drdobbs.com/cpp/enhancing-assertions/184403745). However, I cannot find anything about it that was posted after 2003 nor can I find it on the Boost site. Does anyone know what happened to the project? Was is cancelled or did it make it into Boost under another name? Kind regards, Dano
