=head1 NAME

wrt-config - show configuration values, including defaults

=head1 USAGE

    wrt config

    # Specify a different config file:
    wrt config --config ./wrt.json ...

=head1 DESCRIPTION

C<wrt-config> displays configuration values for the current wrt repository,
including both those overridden in the current F<wrt.json> and those set
by default.

For now, this just uses C<Data::Dumper>, and outputs a whole bunch of stuff
that may not be very interesting, since basically all the values are jammed
into a single object.  Ideally, it could show which values are defaults and
which have been set from a config file or derived from the structure of the
archive.
