$(basename "$0") [-hcpn] [-v VERSION(S)]

Run pytest for empymod locally in an isolated venv before submitting to
GitHub/Travis-CI; by default for all supported python versions of empymod.

where:
    -h : Show this help text.
    -v : Python 3.x version, e.g. '-v 5' for Python 3.5. Default: '4 5 6'.
    -c : Use channel 'conda-forge' instead of channel 'defaults'.
    -p : Print output of conda.
