HOWTO

# cpufrequtils 002
# ================
# Linux kernel with CONFIG_CPU_FREQ and related options set
# sysfsutils
# gawk
# sed
# grep
# gettext (for the utils)

# Older versions used configure, who's default prefix was /usr/local.
# The three digit number versions use a default prefix of /usr.  So,
# skip down to the bottom to remove the old version if you have one
# installed, or pass DESTDIR to make.

# I pass NLS=false to make below because I live in the US and only
# read/write (well) English.  If this is not the case for you, just run
# 'make'.
