    Don't declare all your variables at the beginning
of the script. It works in other languages, but not
in perl. Declare them as you go.

: LOOKING_LINES: while(@line = `cat clicenses_output`){

    Stop using line labels. They work in perl, but they
are rarely needed.

    Why is this output in a loop? Does `cat clicenses_output`
place a new array in @line each time through? Where does it
break its listing?
