# /usr/libexec/path_helper to read /etc/paths and then add items from
# /etc/paths.d/.  In this way, we ensure that the additional items below show up
# in our desired order, or closer, at least, without unsightly duplications or
# going through the extra effort of bash variable expansion to insert in-place.
# The main disadvantage here is that on some older macOS', items in
# /usr/local/bin might not be as high as might be desired, given that it is used
# by Homebrew for intel installations, so some duplication ends up happening.
# Order will be: ~/bin:perlbrew:macports:brew:perl:local_npm:python:etc:git_repos
