+#   variables:
+#
+#       special		block device
+#       mountp		mount point (must match $1, if found)
+#       fstype		file system type
+#       mntopts		file system-specific mount options.
+#	mnttime		time at which file system was mounted
+#
+#   If the mount point can not be found in the standard input stream,
+#   then all fields are set to empty values.  This function assumes that
+#   stdin is already set to /etc/mnttab (or other appropriate input
+#   stream).
