# a temporary home directory and setting $HOME to it,
# then starting a new shell in that directory.
# It also adds the bin directory of ih-core to the
# path to simulate having installed it using brew.
# If you pass "reset" as an argument the test directory
# will be deleted and recreated.
# Any other arguments will be passed to ih-setup in the
# new shell.
