+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
-than two CPU speeds available.  (aka, ARM, AMD K6/K7, Via C3, and
-Crusoe as opposed to traditional Intel and Ultrasparc).
+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).
 
-Powernowd uses the userspace governor, which is included in the Slackware
-kernel images.
+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
 
-It is not wise to run two concurrent cpu frequency adjusting programs,
-for example, cpufreqd and powernowd simultaneously.
+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.

-.SH NAME
-powernowd \- control the speed and voltage of cpus
-.SH SYNOPSIS
-.B powernowd
-.RI [ options ] 
-.SH DESCRIPTION
-This is a simple client to the cpufreq driver, and uses the sysfs interface
-in Linux kernel version 2.6.  You need a supported cpu, and a 
-kernel that supports sysfs to run this daemon.  
-
-The name is somewhat misleading, as any processor supported by the kernel
-cpufreq driver will work, not just processors supporting AMD's 
-PowerNow! technology.  This daemon works best with processors that support 
-more then 2 frequency steps, like those with AMD's PowerNow!, and Intel's
-Pentium M family.
-.SH OPTIONS
-.TP
-.B \-h
-Prints a help message.
-.TP
-.B \-d
-Don't detach from terminal (default is to detach and run in the background)
-.TP
-.B \-v
-Increase output verbosity, can be used more than once.
-.TP
-.B \-q
-Quiet mode, only emergency output.
-.TP
-.B \-n
-Include nice'd processes in calculations.
-.TP
-.B \-m 
-Modes of operation, 0 = SINE, 1 = AGGRESSIVE (default), 2 = PASSIVE, 3 = LEAPS
-.TP
-.B \-s
-Frequency step in kHz (default = 100000)
-.TP
-.B \-p
-Polling frequency in msecs (default = 1000)
-.TP
-.B \-u
-CPU usage upper limit percentage [0 .. 100, default 80]
-.TP
-.B \-l
-CPU usage lower limit percentage [0 .. 100, default 20]
-.SH MODES
-There are 4 modes supported by this client:
-
-Mode 0, SINE, changes the frequency as a sine wave function, raising the 
-frequency by "step" Hz every time the CPU usage goes over 80%,
-and decreases it by "step" Hz when the CPU usage falls under 20%.
-
-Mode 1, AGGRESSIVE, changes frequency by a sawtooth function.	
-Immediately jumps to the highest frequency whenever CPU usage goes 
-over 80%, and decreases by "step" Hz as usage drops below
-20%.  This is the default behavior.
-
-Mode 2, PASSIVE, is the inverse of AGGRESSIVE. 
-Immediately jump to lowest frequency when usage drops below 20%. 
-Raise by "step" Hz if it goes above 80%.
-
-Mode 3, LEAPS, immediately jumps to the highest frequency if usage is above 
-80%, and immediately jumps to the lowest frequency if usage is below 20%.
-.SH PHILOSOPHY
-Why another CPUFreq client daemon?  
-
-Some other daemons are better suited for two speed states, and 
-toggle between two states based upon load.  This daemon does a better job
-handling intermediate steps.
-
-Other daemons are written in Perl, Python, or C++.  This is a simple C 
-program.
-
-Some other daemons rely on APM or ACPI.
-The sysfs interface to the 2.6
-kernel is simple, completely sufficient, and completely portable to all
-architectures that support the CPUfreq support in the kernel.
-
-Some other daemons change thier behavior based upon battery status, AC 
-status, temperature, etc.  What good is having a nice powerful laptop if 
-you can't use it at full speed, even for a few seconds, while on battery 
-power?  This daemon just measures CPU load, and bases decisions solely 
-upon that.  
-
-SMP systems are supported, making this daemon useful for servers, too!
-.SH AUTHOR
-The powernowd program was written by John Clemens <clemej@alum.rpi.edu>
-
-This manual page was written by Bdale Garbee <bdale@gag.com>,
-for the Debian project (but may be used by others).
