Modular Debugger

Modular debugger (mdb) is a new extensible utility for low-level debugging and editing of the live operating system, operating system crash dumps, user processes, user process core dumps, and object files. mdb provides a completely customizable environment for debugging complex software systems, such as an operating system, for programs that are highly optimized, have had their debug information removed, or are themselves low-level debugging tools. mdb also handles customer situations where developers can access only post-mortem information.
