Title: Devel

Choose the tool to set a scaling governor according to the presence of the intel pstate driver.
To take advantage of these changes an user has to install the package linux-tools or build cpupower from the kernel source tree.
Otherwise, he won't be ablte to set the scaling governor. The usual way (writing to /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor) is not praticable on systems with intel_pstate enabled, because the kernel refuses to write into that file.
