# You must replace "quagga" and "QUAGGA" 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.

#
# QUAGGA_VERSION, QUAGGA_SITE and QUAGGA_SOURCE define
# the upstream location of the source code for the package.
# QUAGGA_DIR is the directory which is created when the source
# archive is unpacked.
# QUAGGA_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.
