=head1 NAME
Module::Install::TrustMetaYml - trusts META.yml list of dependencies
=head1 SYNOPSIS
In Makefile.PL:
        trust_meta_yml;
=head1 DESCRIPTION
CPAN doesn't trust C<META.yml>'s list of dependencies for a module. Instead it
expects C<Makefile.PL> run on the computer the package is being installed
upon to generate its own list of dependencies (called C<MYMETA.yml> or
C<MYMETA.json>).
This module is a Module::Install plugin that generates C<MYMETA.yml> by simply
passing through the dependencies from C<META.yml>.
It does nothing when run from the module author's development copy.
The module defines two functions which are aliases for each other:
=over
=item C<trust_meta_yml>
=item C<trust_meta_yaml>
=back
=head1 BUGS

Thanks to Chris Williams (BINGOS), Ingy döt Net (INGY) and Florian Ragwitz (FLORA)
for explaining the role of C<MYMETA.json>, and helping me figure out why mine
weren't working.
