28mdb(1) is an extensible utility for low-level debugging and editing of the
29live operating system, operating system crash dumps, user processes, user
30process core dumps, and object files. mdb provides a completely customizable
31environment for debugging complex software systems such as an operating system,
32for programs that are highly optimized, have had their debug information
33removed, or are themselves low-level debugging tools, and for customer
34situations where developers can only access post-mortem information.
36Refer to the white paper "A Modular Debugger for Solaris" for information
37on the design, features, and goals of MDB. See /shared/sac/PSARC/1999/169
38for copies of the paper and related documentation. More information about
39MDB is available on the internal web at http://mdb.eng/. This directory
40contains both the source for the MDB debugger, and the supporting debugger
41modules. Developers are free to modify and enhance these modules to add
42new dcmds and walkers and to create completely new modules.
