+EXAMPLES
+========
+To set a package-level power limit on socket 0 (add -v for a verbose print out):
+
+    ./msrmod -s package -c 0 -a 100 -b 1 -e 120 -f 3 (-v)
+
+To restore default power limits on socket 1:
+
+    ./msrmod -s default -c 1
+
+To see current package-level and dram-level power limits:
+
+    ./msrmod -p rapl
+
+To explicitly write a new hex value into register MSR_PKG_POWER_LIMIT 0x610 on
+CPU 3 (i.e., socket 0):
+
+    ./msrmod -w 610 -t 3 -d 7845000158320
