+#     on what happened when the system crashed.  This report can be
+#     analyzed by SGI support personnel in order to try and find out
+#     why the system either paniced or hung.
+#
+# summary.N:
+#     The summary information about a crash, primarily used by the
+#     availmon information gathering process.  Note that this file
+#     is removed as soon as 'availmon' picks it up.
+#
+# unix.N:
+#     A copy of /unix from the time of the system crash.

+# vmcore.N.comp:
+#     A compressed version of the virtual memory at the time of the
