# virtualenv activation module:
# - Activate with `overlay use activate.nu`
# - Deactivate with `deactivate`, as usual
#
# To customize the overlay name, you can call `overlay use activate.nu as foo`, but then simply `deactivate` won't work
# because it is just an alias to hide the "activate" overlay. You'd need to call `overlay hide foo` manually.
