# execute this script with no arguments.

# Optionally override the Python interpreter with `$PYTHON3`, or
|
|
# with the `-p <path_to_python3>` option. It defaults to
|
|
# `python3`, which is usually correct.

# Normally, this script refuses to install unless a virtual env is
|
|
# active. This avoids making accidental system-wide changes. A user
|
|
# can override this safety measure with `-f`.

# Our workspace setup requires a specific version of poetry to be
|
|
# installed, this script automates the pip install of that version.
