=head1 NAME
Module::Depends - identify the dependencies of a distribution
=head1 SYNOPSIS
use Module::Depends;
my $deps = Module::Depends->new->dist_dir( '.' )->find_modules;
print "Our dependencies:\n", Dump $deps->requires;
=head1 DESCRIPTION
Module::Depends extracts module dependencies from an unpacked
distribution tree.
Module::Depends only evaluates the META.yml shipped with a
distribution. This won't be effective until all distributions ship
META.yml files, so we suggest you take your life in your hands and
look at Module::Depends::Intrusive.
=head1 METHODS
=head2 new
simple constructor
=cut
sub new {
my $self = shift;
return $self->SUPER::new({
libs => [],
requires => {},
build_requires => {},
test_requires => {},
configure_requires => {},
error => '',
});
}
=head2 dist_dir
Path where the distribution has been extracted to.
=head2 find_modules
scan the C<dist_dir> to populate C<libs>, C<requires>, C<configure_requires>, C<test_requires>, and C<build_requires>
