Virtualenv installation:

Run ./vinstall.sh to generate the python virtualenv and install requirements.

Default looks for python3 on the system.
It will setup a virtualenv within a "venv" directory (same level as vinstall.sh file).
It should also write a shell wrapper to run mpd-sima within the virtualenv.

	./vmpd-sima --help

You might specify a python3 interpreter if the binary name differs from python3:

    PY3=/usr/bin/python ./vinstall.sh

You can locate the virtalenv somewhere else:

    INSTALL_DIR=/tmp/crap_test/ ./vinstall.sh
