Arquivo zf.php diferente do esperado

Boa tarde,

Quando instalo o zftool com o comando:

composer require zendframework/zftool:dev-master

o arquivo .vendor\bin\zf.php não ficou como esperado no tutorial e sim da seguinte maneira:

#!/usr/bin/env sh

dir=$(d=${0%[/\\]*}; cd "$d"; cd "../zendframework/zftool" && pwd)

# See if we are running in Cygwin by checking for cygpath program
if command -v 'cygpath' >/dev/null 2>&1; then
    # Cygwin paths start with /cygdrive/ which will break windows PHP,
    # so we need to translate the dir path to windows format. However
    # we could be using cygwin PHP which does not require this, so we
    # test if the path to PHP starts with /cygdrive/ rather than /usr/bin
    if [[ $(which php) == /cygdrive/* ]]; then
        dir=$(cygpath -m "$dir");
    fi
fi

dir=$(echo $dir | sed 's/ /\ /g')
"${dir}/zf.php" "$@"

Alguém sabe o que pode ser?
