=head1 NAME

    select-default-wordlist - select default wordlist

=head1 SYNOPSIS

 select-default-wordlist [options]

  Options (all long only options):
    --set-default='regexp' Try 'regexp' to get a single match and set
                           it as default. Fail otherwise.
    --show-choices         Show available choices to STDERR and exit.
    --debug                Enable debug mode

=head1 DESCRIPTION

This program is responsible for selecting default
wordlist.

If B<--show-choices> is used will just output a list of available
choices to STDERR and exit.
STDOUT cannot be used, this program loads B<debconf> and B<debconf>
captures STDOUT.

If B<--set-default> is used, program will try to get a single regexp
match from available choices, failing if not.
Will try case dependent match first, then case independent.

If B<--set-default> is not used this program will make debconf always
ask the shared question about the default wordlist to be used in your system according to the
installed ones.

In both cases, will do the appropriate settings if needed.

Calls internally B<update-default-wordlist>.
