+// Searching system-release (Red Hat) and os-release (other Linuxes) are a
+// next to last resort.  The os-release file is a new standard that contains
+// distribution information and the system-release file seems to be an old
+// standard that has been replaced by the lsb-release and os-release files.
+// Searching for the debian_version file is the last resort.  It contains
