+ (description
+ "Powerstat measures and reports your computer's power consumption in real
+time. On mobile PCs, it uses ACPI battery information to measure the power
+drain of the entire system.
+
+Powerstat can also report @acronym{RAPL, Running Average Power Limit} power
+domain measurements. These are available only on some hardware such as Intel
+Sandybridge and newer, and cover only part of the machine's components such as
+CPU, DRAM, and graphics. However, they provide accurate and immediate readings
+and don't require a battery at all.
+
+The output is like @command{vmstat} but also shows power consumption
statistics:
+at the end of a run, @command{powerstat} will calculate the average, standard
+deviation, and minimum and maximum values. It can show a nice histogram too.")
