Declarations

• Declare variables near where they are used

• This tends to keep the scope small

• Easier on the maintenance programmer

• So for example, instead of:

     484      my ($first_file);
        ... 65 lines omitted ...
     550      while ($first_file = shift (@file_list))

• Just use:

      while (my $first_file = shift (@file_list))

• This also eliminates a line of useless clutter
