# In zsh the value of $0 depends on the FUNCTION_ARGZERO option which is
# set by default. FUNCTION_ARGZERO, when it is set, sets $0 temporarily
# to the name of the function/script when executing a shell function or
# sourcing a script. POSIX_ARGZERO option, when it is set, exposes the
# original value of $0 in spite of the current FUNCTION_ARGZERO setting.
#
# Note: The version of zsh need to be 5.0.6 or above. Any versions below
# 5.0.6 maybe encoutner errors when sourcing this script.
