# bootstrap-toolshelf.sh:
# A script which sets up the toolshelf environment for you for the
# first time, intended to be `source`d.
# We structure this script as one big function (for now), so that we can
# prematurely stop (we can't do this by calling `exit`, because if this script
# is being `source`d, that would terminate the user's shell.)
# TODO: refactor this one function into smaller, more useful functions
