+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).
+
+Powernowd uses the userspace governor, which is included in the Slackware
+kernel images.
+
+It is not wise to run two concurrent cpu frequency adjusting programs,
+for example, cpufreqd and powernowd simultaneously.

+.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).
