+# == Define: apt::key
+#
+# The apt::key defined type allows for keys to be added to apt's keyring
+# which is used for package validation. This defined type uses the apt_key
+# native type to manage keys. This is a simple wrapper around apt_key with
+# a few safeguards in place.
+#
+# === Parameters
+#
+# [*key*]
+# _default_: +$title+, the title/name of the resource
+#
+# Is a GPG key ID. This key ID is validated with a regex enforcing it
+# to only contain valid hexadecimal characters, be precisely 8 or 16
+# characters long and optionally prefixed with 0x.
+#
+# [*ensure*]
+# _default_: +present+
+#
+# The state we want this key in, may be either one of:
+# * +present+
+# * +absent+
+#
+# [*key_content*]
+# _default_: +undef+
+#
+# This parameter can be used to pass in a GPG key as a
+# string in case it cannot be fetched from a remote location
+# and using a file resource is for other reasons inconvenient.
+#
+# [*key_source*]
+# _default_: +undef+
+#
+# This parameter can be used to pass in the location of a GPG
+# key. This URI can take the form of a:
+# * +URL+: ftp, http or https
+# * +path+: absolute path to a file on the target system.
+#
+# [*key_server*]
+# _default_: +undef+
+#
+# The keyserver from where to fetch our GPG key. It can either be a domain
+# name or url. It defaults to
+# undef which results in apt_key's default keyserver being used,
+# currently +keyserver.ubuntu.com+.
+#
+# [*key_options*]
+# _default_: +undef+
+#
+# Additional options to pass on to `apt-key adv --keyserver-options`.
