If you are often interacting with the same device, you can set the environment
variable ``PYBOARD_DEVICE`` as an alternative to using the ``--device``
command line option. For example, the following is equivalent to the previous
example::
$ export PYBOARD_DEVICE=/dev/ttyACM0
$ pyboard.py -c 'print(1+1)'
Similarly, the ``PYBOARD_BAUDRATE`` environment variable can be used
to set the default for the `--baudrate` option.
