@hsaputra This is just refactoring. I think your changes improve the
readability of the code. Like Ufuk mentioned, it does not necessarily make the
script more flexible. Due to side effects of the function calls they need to be
called in a specific order. It does make the script "a bit more flexible"
though :)
