| * power_save.h - Support node power saving mode. Nodes which have been |
| * idle for an extended period of time will be placed into a power saving |
| * mode by running an arbitrary script. This script can lower the voltage |
| * or frequency of the nodes or can completely power the nodes off. |
| * When the node is restored to normal operation, another script will be |
| * executed. Many parameters are available to control this mode of operation. |
