+pstate-frequency is able to adjust the Intel p-state driver
+values for the minimum and maximum scaling frequencies and
+the state of turbo boost.
+
+You can enable optional feature by passing variables to
+the script (ie. VAR=yes/no ./pstate-frequency.SlackBuild) :
+
+WITH_UDEV_RULE=yes|no (default:no)
+ Installs an udev rule for automatic frequency setting
+ when the power source thas changed.
+
+WITH_COMPLETION=yes|no (default:no)
+ Installs bash & zsh completion.

+Optional Dependencies :
+
+ * x86_energy_perf_policy
+ This is used to set the CPU to normal performance
+ policy upon suspend and resume. It is used to
+ currently work around an assumed bug whereby on
+ resume the system is set to performance policy on
+ one core. It can help fix issues where upon resume
+ of the system, the CPU runs at frequencies higher
+ than that which is advertised to be available.
