 The configuration below creates two classes class1 and class2 and
 assigns shares of 1024 to class1 and 512 to class1.
 
+The other options that can be specified are
+
+tuid = owner of the tasks file
+tgid = group permissions of the tasks file
+cuid = owner of the newly created node
+cgid = group permissions of the newly created node
+
+Example
+
+class1 cpu.shares = 1024 tuid=root tgid=root cuid=database cgid=database.
+
+By default all these files are owned by root. The flexibilty of specifying
+owners makes it easier for other applications to use resource management.
