# ============ #
# Initial test #
# ============ #

# This script is primarily a shell function library, but it is put on the PATH
# to be able to load it using ". ssft.sh" (the idea was taken from the
# gettext.sh program).
#
# We use a function to test if the script has been called instead of sourced
# and in that later case we accept the --help and --version options.
# 
# The test is defined inside a function to be able to source the script from
# zsh, as this shell by default sets the option FUNCTION_ARGZERO that replaces
# the $0 variable for sourced scripts and functions; using a function we are
# sure that if FUNCTION_ARGZERO is set, $0 never takes the program name. Note
# that using this method if we execute the script using zsh the default
# options we will not see the --help or --version messages, but that is not
# important, as the executable script is run using '/bin/sh' and we get the
# desired efect when it is called directly.
