+    help
+      If you say 'y' here, then an interactive shell will be spawned for
+      each failed command.
+      
+      This shell will have the same environment that the failed command
+      was run with, and the working directory will be set to the directory
+      the failed command was run in.
+      
+      After you fix the issue, you can exit the interactive shell with any
+      of these exit codes:
+        1  the issue was fixed, continue the build with the next command
+        2  the issue was fixed, re-run the failed command
+        3  abort the build
+      
+      Note: '2' is only possible for commands run via CT_DoExecLog, though.
