 ## i3block_py
 A collection of standalone python scripts for the slightly more complicated things.  
 * **energy.py**: parses `acpi` to output current battery status. Uses `notify-send` to send messages on changes.
+* **cpy.py**: parses `/proc/loadavg` to output load average values for last 1, last 5 and last 15 min.
+    * call `cpy.py 1` to get the avg from last min
+    * call `cpy.py 5` to get the avg from last 5 min
+    * call `cpy.py 15` to get the avg from last 15 min
