+## rasdaemon is a RAS (Reliability, Availability and Serviceability) logging
+## tool.  It currently records memory errors, using the EDAC tracing events.
+## EDAC are drivers in the Linux kernel that handle detection of ECC errors
+## from memory controllers for most chipsets on x86 and ARM architectures.
