# You must replace "scons" and "SCONS" 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.

#
# SCONS_VERSION, SCONS_SITE and SCONS_SOURCE define
# the upstream location of the source code for the package.
# SCONS_DIR is the directory which is created when the source
# archive is unpacked.
# SCONS_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.

# This target also configures the build within the build directory.
# Flags such as LDFLAGS and CPPFLAGS should be passed into configure

# correctly BUILD the Makefile with the right paths, where passing it
# to Make causes it to override the default search paths of the compiler.

# If the compilation of the package requires other packages to be staged
# first, then do that first (e.g. "$(MAKE) <bar>-stage <baz>-stage").

# If the package uses  GNU libtool, you should invoke $(PATCH_LIBTOOL) as
# shown below to make various patches to it.
