 # Use this to update compat-wireless-2.6 to the latest
 # wireless-testing.git tree you have.
 #
 # Usage: you should have the latest pull of wireless-2.6.git
 # git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-testing.git
 # We assume you have it on your ~/devel/wireless-testing/ directory. If you do,
 # just run this script from the compat-wireless-2.6 directory.
 # You can specify where your GIT_TREE is by doing:
 #
 # export GIT_TREE=/home/mcgrof/wireless-testing/
 #
 # for example
