@summary Example resource type using the new API.
@raise SomeError
This type provides Puppet with the capabilities to manage GPG keys needed
by apt to perform package validation. Apt has it's own GPG keyring that can
be manipulated through the `apt-key` command.
@example here's an example
  apt_key { '6F6B15509CF8E59E6E469F327F438280EF8D349F':
    source => 'http://apt.puppetlabs.com/pubkey.gpg'
  }

**Autorequires**:
If Puppet is given the location of a key file which looks like an absolute
path this type will autorequire that file.
