This is an initialized openwrt build environment, for the Wireless Battle of the Mesh.
It's a clone of git://nbd.name/openwrt.git at some point in time; from that point it adds a few commits to include an appropiate feeds.conf and env configs.
The included feeds.conf points the 'packages' feed to git://github.com/battlemesh/openwrt-packages.git , which is a snapshot (at a particular point in time) of the original git://nbd.name/packages.git
So what you get is a particular openwrt trunk revision, of both the base source code and the packages feed.
git clone -b wbm2013 git://github.com/battlemesh/openwrt.git
cd openwrt
./scripts/feeds update -a
git pull
./set_environment.sh
make V=99
./set_environment.sh mr3040
make V=99
./set_environment.sh mr3020
make V=99
./set_environment.sh x86
make V=99
If you want to bring this snapshot to the current upstream release/revision, you must fetch the upstream changesets, merge them, (and probably push them back to github); do this for both the base and packages repositories.
