-Overview:
 This is a very simple program that will adjust the speed of your CPU
-depending on system load.  It works as a client of the CPUFreq driver.
-It is designed for use with CPU's supporting AMD's PowerNow power management
-scheme, as it's algorithm works better if there are more then two CPU
-speeds available.  (aka, ARM, AMD K6/K7, Via C3, and Crusoe as opposed to
-traditional Intel and Ultrasparc).
+depending on system load.
 
-This program is essentially a simple client to the CPUFreq sysfs interface.
-This means that you -need- to be running Linux v2.5 or later that includes
-the sysfs interface.  This daemon will -not- work with the CPUFreq driver
-interface included in Linux v2.4.  Feel free to write your own daemon
-to support that if you like; you can even use this as a starting point.
-If there's enough clamoring for it, then maybe I'll whip up something.
-You also need a CPU that supports frequency scaling and supports the CPUFreq
-interface.  This code has been tested on various AMD and PPC processors

-I have been running this daemon on my AMD laptop for over 2 years with no
-problems to report, and it's nice that my laptop remains cool unless I'm
-really doing something intensive, like watching DivX movies, without me
-having to manually intervene and set the speed. I just recently bought an
-Apple iBook G3, and powernowd-0.80 worked flawlessly on it right out of
-the box.

-Features:
-
-This daemon's goal is simplicity and speed.  It doesn't try and make
-too many decisions for you.  That's its beauty, but it may not be what
-everyone's looking for. Some of the features this daemon has:
-
-One, simple heuristic to determine CPU load: "user + sys" time.
-Ignore "niced" programs (setiathome, itself, etc). In my mind this is
-consistent with what is meant when someone 'nice's a program to begin
-with. (configurable in v0.85+) Designed for CPU's that support more
-then two speed states, but works well with anything.  Very fast, low
-overhead /proc/stat gathering (method stolen from procps).  Supports SMP
-Will automatically switch to 'userspace' governor.  Care taken to make
-the code non-root exploitable (but please audit for yourself first!)
-Frequency step size is configurable (default to 100MHz/step) 4 different
-behavioral modes to choose from (SINE, AGGRESSIVE, PASSIVE, LEAPS),
-which determine the behavior when the load changes. Configurable from the
-command line.  Written in C for speed and simplicity.  Logging to stdout
-or syslog Configurable Polling frequency in milliseconds (defaults to 1s)
-Configurable highwater/lowwater marks for CPU usage. (defaults 80/20%)
-
-Many similar daemons use other methods to determine what speed to use,
-such as battery status, AC status, temperature, fan status, etc. They all
-have their place.  I however feel that in the grand scheme of things none
-of the above matters. When I'm not using my CPU, I don't care if it's
-running at a slower speed. When I -am- using my CPU, I only need it to
-be fast enough to handle the task at hand without hiccuping. And when I'm
-taxing my CPU, I want it running full speed. That's all this daemon does,
-monitor CPU load and adjust the speed accordingly.  Since in all reality
-my CPU is idle 99% of the time (or playing mp3's which it can easily do
-at it's lowest speed rating), this by definition leads to low power usage,
-low temperatures, low speed fans, and better battery life.
+This program is essentially a simple client to the CPUFreq sysfs
+interface.  This means that you -need- to be running Linux v2.5 or later
+that includes the sysfs interface.
