The \texttt{for} loop's initial statement is the declaration of the \texttt{s} variable as an empty string; thereafter follows the condition of \texttt{args} not equalling \texttt{nil}; and lastly the command \texttt{args = tl args} is supposed to be executed, videlicet discarding the head of the \texttt{args} variable; this is to be done until \texttt{args} no longer contains any data — id est when its value has become \texttt{nil}.

The successive line then attaches a space — \texttt{" "} — onto the \texttt{s} variable, plucks the head from the \texttt{args} variable and, lastly, adjoins it to the \texttt{s} variable; thereupon the loop is executed again, yet this time, the \texttt{args} variable has had one of its arguments expunged.
