Introduction to Cpufrequtils
The cpufrequtils package consists of a library which offers an unified access method for userspace tools and programs to the CPU frequency and voltage scaling (cpufreq) subsystem in the Linux kernel, the "cpufreq-info" and "cpufreq-set" tools to determine and set cpufreq settings, and debug tools helpful if frequency scaling doesn't work as expected.

Short Description
| cpufreq-info | determines current cpufreq settings, and provides useful
debug information to users and bug-hunters. |
|---|---|
| cpufreq-set | allows to set a specific frequency and/or new cpufreq policies
without having to type "/sys/devices/system/cpu/cpu0/cpufreq" all the time. |
| cpufreq-aperf | calculates and displays average CPU frequency. |
