# Upgrade any out-of-date pip packages
# HACK: It would be better to include the logic for updating pip packages right
# here, but direnv waits for all subshells and functions to finish before it
# initializes the environment, which causes a noticeable hang when cd-ing into
# the repository. Running a script in the background does not cause a delay.
