+	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).
