+ *
+ * @brief RTEMS Module Loading Debugger Interface.
+ *
+ * Inspection of run-time linkers in NetBSD and Android show a common type of
+ * structure that is used to interface to GDB. The NetBSD definition of this
+ * interface is being used and is defined in <link.h>. It defines a protocol
+ * that is used by GDB to inspect the state of dynamic libraries. I have not
+ * checked GDB code at when writing this comment but I suspect GDB sets a break
+ * point on the r_brk field of _rtld_debug and it has code that detects this
+ * break point being hit. When this happens it reads the state and performs the
+ * operation based on the r_state field.
