CLI utility for using Singularity container as virtual environment (requires singularity to already be installed).

$ basis --help
Usage: basis [OPTIONS] [CMD]...

Options:
  -i, --image TEXT
  -a, --app TEXT    {bash, fish, jupyter, code}
  -b, --basis PATH
  -w, --work PATH
  -c, --cwd PATH
  --help            Show this message and exit.

The first time it is run it will download a pre-build Singularity image. You must also tell it where to create the basis directory on the first run, which will become a virtual home inside the container.
