+"libcpufreq" is a library which offers a unified access method for userspace
+tools and programs to the cpufreq core and drivers in the Linux kernel. This
+allows for code reduction in userspace tools, a clean implementation of
+the interaction to the cpufreq core, and support for both the sysfs and proc
+interfaces [depending on configuration].
+"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.
