From 21beeed3c257e43b557edf01114fc752d4123125 Mon Sep 17 00:00:00 2001
From: Tom Rondeau <trondeau@vt.edu>
Date: Thu, 6 Oct 2011 17:04:47 -0400
Subject: uhd: moved fm_tx_2_daughterboards and usrp_spectrum_sense to
gr-uhd/examples. Neither are working properly quite yet.
Removed all usrp examples from gnuradio-examples/python/usrp and removed directory.
