"If we want beyond what it provides by default, we tell it a bit more. In this "

"specify what is known as a positional argument. It's named so because the "
"program should know what to do with the value, solely based on where it "
"appears on the command line. This concept is more relevant to a command like :"
"command:`cp`, whose most basic usage is ``cp SRC DEST``. The first position is "
"*what you want copied,* and the second position is *where you want it copied "
