=head1 NAME

Module::Build::JSONMETA - (depreacted) write META.json instead of META.yml

=head1 SYNOPSIS

B<Achtung!>  This library will soon be obsolete as Module::Build moves to use
the official L<CPAN::Meta::Spec> JSON files.

This interface may be changed in the future if someone with more Module::Build
expertise steps forward.
