[Discuss-gnuradio] Question on using USRP sink/sources in GNU Radio recent release

[Samudra E Haque]

Hello, as some of you may know I recently installed a fresh GNURADIO
package, after a manual install of a UHD package on my Ubuntu 10.04 LTS
workstation.

dpkg -i UUHD-003.003.001-Ubuntu-10.04-x86_64.deb

(from git)
cat version.sh
MAJOR_VERSION=3
API_COMPAT=5
MINOR_VERSION=0rc0
MAINT_VERSION=0

So far so good, Gnu Radio Companion works etc., uhd_fft.py, Audio examples
work etc.

My test setup: USRP/TVRX2 -- USB -- USB (UHD) -- HOST

However, as I had attempted earlier installs, some old files remain. My
question is: are the files provided in the following list already
deprecated? The majority of them include "from gnuradio import usrp" or
"from gnuradio import usrp2" string in their header, and I have confirmed
even the most basic example listed in http://www.joshknows.com/gnuradio
(See USRP Examples) fails. So, is there a recommended way to modify these
python files to use the UHD driver instead of (missing?) USRP or USRP2
blocks? If these files will not be needed anymore (as UHD supercedes
USRP), why keep them around on public websites? But if they have any
educational value, then why not keep a "stub" usrp entry that spits out an
error message to the calling script with a blurb of something like
"feature deprecated, please use UHD".. so that old code examples can be
ported to newer coding standards?

Traceback (most recent call last):
  File "foo.py", line 2, in <module>
    from gnuradio import usrp
ImportError: cannot import name usrp

Now a general question for the archive-maintainers, is there a handy
reference of the supported/tested status of each of these files? I see
that (I believe..) none of the files have a timestamp or author
information, or even a specification block as to the exact test
environment this code was executed in. Is that information available
elsewhere as a release note accompanying the package or only available
through a git log entry?
