Re: [Omaha.pm] Getopt::Long and opt_ variables

Note that, if your code is running under the recommended use strict 'vars'
pragma, it may be helpful to declare these package variables via use vars
perhaps something like this:

  use vars qw/ $opt_size @opt_sizes $opt_bar /;
</quote>

so ... you just need to add,

use vars qw/ $opt_place /;

OR

remove the statement,

use strict;
