# Usage:
#
# in an existing kernel directory, run:
#
# ketchup <version>
#
# where version is a complete kernel version, or a branch name to grab
# the latest version (see the available trees)
#
# You can override some variables by creating a ~/.ketchuprc file.
# The ~/.ketchuprc is just a Python script, eg. it might look like this:
#
# kernel_url = 'http://kernel.localdomain/pub/linux/kernel'
# archive = os.environ["HOME"] + '/tmp/ketchup-archive'
# gpg = '/weird/path/to/gpg'
