# You must replace "cpufrequtils" and "CPUFREQUTILS" with the lower case name and
# upper case name of your new package.  Some places below will say
# "Do not change this" - that does not include this global change,
# which must always be done to ensure we have unique names.

#
# CPUFREQUTILS_VERSION, CPUFREQUTILS_SITE and CPUFREQUTILS_SOURCE define
# the upstream location of the source code for the package.
# CPUFREQUTILS_DIR is the directory which is created when the source
# archive is unpacked.
# CPUFREQUTILS_UNZIP is the command used to unzip the source.
# It is usually "zcat" (for .gz) or "bzcat" (for .bz2)
#
# You should change all these variables to suit your package.
# Please make sure that you add a description, and that you
# list all your packages' dependencies, seperated by commas.
# 
# If you list yourself as MAINTAINER, please give a valid email
# address, and indicate your irc nick if it cannot be easily deduced
# from your name or email address.  If you leave MAINTAINER set to
# "NSLU2 Linux" other developers will feel free to edit.

CPUFREQUTILS_DESCRIPTION=To make access to the Linux kernel cpufreq subsystem easier for users and cpufreq userspace tools, a cpufrequtils package was created. It contains a library used by other programs (libcpufreq), command line tools to determine current CPUfreq settings and to modify them (cpufreq-info and cpufreq-set), and debug tools.
