# Ordinarily the way to do this would probably be to use a heredoc. Something like:
#
# ```
# rebar3 hex publish <<EOF
# y
# $LOCAL_PASSWORD
# $LOCAL_PASSWORD
# ```
#
# However there's something funny around (I think) prompts and spawning processes going on,
# where rebar3 will crash if we send it the local password too quickly.
