    my $help = "LLAW Google Civic Information API Query version 1
Copyright (C) 2023 - by Jonathan Rosenbaum <freesource\@freesoftwarepc.com>
This may be freely redistributed under the terms of the GNU General Public License

Usage:  $0 google ./roster-file  (queries Google Civic Api Delegate and Senate District for all LWVWV members)
        $0 WV000 ./roster-file (show all information for members at large, but do not query Google)
        $0 WV000 ./roster-file email (only show email addresses for members at large, but do not query Google)

1st argument can be one of these types:
    google (all members with senate/delegate district query) which prints out this csv data:
        'Name,Email,Phone,Address,Delegate District,Senate District,Join Date'
    ALL (all members without senate/delegate district query)
    League ID:  WV000 (members at large)  WV102 (Huntington) WV103 (Morgantown-Monogalia) WV107 (Wood County) WV112 (Jefferson)

2nd argument must be the location of the LWVWV roster file, and prints out this csv information:
    Name,Email,Phone,Address,Join Date,

3rd argument 'email' will only print out the email addresses, and only works with the ALL or League ID type argument
    

You will want to send results to a file.
Example:  $0 google ./roster-file > 2023-districts
