This is 'iw', a tool to use nl80211.
To build iw, just enter 'make'. If that fails, set the
PKG_CONFIG_PATH environment variable to allow the Makefile
to find libnl.
'iw' is currently maintained at http://git.sipsolutions.net/iw.git/,
some more documentation is available at
https://wireless.wiki.kernel.org/en/users/Documentation/iw
Please send all patches to Johannes Berg johannes@sipsolutions.net
and CC linux-wireless@vger.kernel.org for community review.
