+"A context object that provides access to core debugger entities.
+
+Manay debugger functions require a context when doing lookups. This class
+provides a common structure that can be used as the result of a query that
+can contain a single result.
+
+For example,
+
+        exe = os.path.join(os.getcwd(), 'a.out')
+
+        # Create a target for the debugger.
+        target = self.dbg.CreateTarget(exe)
+
+        # Now create a breakpoint on main.c by name 'c'.
+        breakpoint = target.BreakpointCreateByName('c', 'a.out')
+
+        # Now launch the process, and do not stop at entry point.
+        process = target.LaunchSimple(None, None, os.getcwd())
+
+        # The inferior should stop on 'c'.
+        from lldbutil import get_stopped_thread
+        thread = get_stopped_thread(process, lldb.eStopReasonBreakpoint)
+        frame0 = thread.GetFrameAtIndex(0)
+
+        # Now get the SBSymbolContext from this frame.  We want everything. :-)
+        context = frame0.GetSymbolContext(lldb.eSymbolContextEverything)
+
+        # Get the module.
+        module = context.GetModule()
+        ...
+
+        # And the compile unit associated with the frame.
+        compileUnit = context.GetCompileUnit()
+        ...
