how these directories' code is shared, and with whom.
--- /dev/null
+The files in this directory are shared with Wind River Systems' VxWorks
+debug stub. This stub runs in the realtime system, as a process, and
+waits for net connections from GDB's and DBX's and such.

+Do not change these files without coordinating with Wind River Systems
+in Alameda, California. Talk to postmaster@wrs.com to find out who
+currently maintains GDB for them.
