+   identifying the inferior process/thread being debugged.  When
+   manipulating ptids, the constructors, accessors, and predicate
+   declared in server.h should be used.  These are as follows:
+
+      ptid_build	- Make a new ptid from a pid, lwp, and tid.
+      pid_to_ptid	- Make a new ptid from just a pid.
+      ptid_get_pid	- Fetch the pid component of a ptid.
+      ptid_get_lwp	- Fetch the lwp component of a ptid.
+      ptid_get_tid	- Fetch the tid component of a ptid.
+      ptid_equal	- Test to see if two ptids are equal.
+
+   Please do NOT access the struct ptid members directly (except, of
