getting started: python scripts

Hi, I'm just getting started with the osmo-tetra, and following the wiki (https://osmocom.org/projects/tetra/wiki/Osmo-tetra). However, I do not see the python scripts in the git source code. For example, I cannot find: src/demod/python/tetra-demod.py * call demodulator on a 'cfile' containing complex baseband samples src/demod/python/usrp1-tetra_demod.py * use demodulator in realtime with a USRP1 SDR src/demod/python/usrp2-tetra_demod.py * use demodulator in realtime with a USRP2 SDR Jeff
