+	help
+	  emlog is a Linux kernel module that makes it easy to access
+	  the most recent (and only the most recent) output from a
+	  process. It works just like "tail -f" on a log file, except
+	  that the storage required never grows. This can be useful in
+	  embedded systems where there isn't enough memory or disk
+	  space for keeping complete log files, but the most recent
+	  debugging messages are sometimes needed (e.g., after an
+	  error is observed).
