# 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.
