CPANPLUS::Module::Author
=head1 SYNOPSIS
my $author = CPANPLUS::Module::Author->new(
author => 'Jack Ashton',
cpanid => 'JACKASH',
_id => INTERNALS_OBJECT_ID,

=head1 DESCRIPTION
C<CPANPLUS::Module::Author> creates objects from the information in the
source files. These can then be used to query on.
These objects should only be created internally. For C<fake> objects,
there's the C<CPANPLUS::Module::Author::Fake> class.
=head1 ACCESSORS
An objects of this class has the following accessors:
=over 4
=item author
Name of the author.
=item cpanid
The CPAN id of the author.
=item email
The email address of the author, which defaults to '' if not provided.
=item parent
The C<CPANPLUS::Internals::Object> that spawned this module object.

cpanid => { required => 1 }, # cpan id
email => { default => '' }, # email address of the author
_id => { required => 1 }, # id of the Internals object that spawned us
};

next if $mod->package_extension( $name ) eq META_EXT;

### (which is wrong anyway, as we're doing a different module),
### which in turn calls ->contains, which scans the entire
### module tree using _search_module_tree, which uses P::C
### and is therefor VERY VERY slow.
### so let's do this the direct way for speed ups.
