     28 mdb(1) is an extensible utility for low-level debugging and editing of the
     29 live operating system, operating system crash dumps, user processes, user
     30 process core dumps, and object files.   mdb provides a completely customizable
     31 environment for debugging complex software systems such as an operating system,
     32 for programs that are highly optimized, have had their debug information
     33 removed, or are themselves low-level debugging tools, and for customer
     34 situations where developers can only access post-mortem information.
     35 
     36 Refer to the white paper "A Modular Debugger for Solaris" for information
     37 on the design, features, and goals of MDB.  See /shared/sac/PSARC/1999/169
     38 for copies of the paper and related documentation.  More information about
     39 MDB is available on the internal web at http://mdb.eng/.  This directory
     40 contains both the source for the MDB debugger, and the supporting debugger
     41 modules.  Developers are free to modify and enhance these modules to add
     42 new dcmds and walkers and to create completely new modules.
