+ * where "nn" is the lwpid of the LWP that the information belongs
+ * to (such as register state).
+ *
+ * We use the following note identifiers:
+ *
+ * ELF_NOTE_NETBSD_CORE_PROCINFO
+ * Note is a "netbsd_elfcore_procinfo" structure.
+ *
+ * We also use ptrace(2) request numbers (the ones that exist in
+ * machine-dependent space) to identify register info notes. The
+ * info in such notes is in the same format that ptrace(2) would
+ * export that information.
+ *
+ * Please try to keep the members of this structure nicely aligned,
+ * and if you add elements, add them to the end and bump the version.
