+#
+# == Define: apparmor::profile
+#
+# Install an Apparmor profile and a local profile to add/override some rules
+#
+# === Parameters
+#
+# [*default_base*]
+#  Default path to use with $source and $local_source. If unset (default),
+#  defaults to a distro specific path.
+#
+# [*source*]
+#   Source path to the Apparmor profile. If unset (default), defaults to
+#   "${default_base}/${name}".
+#
+# [*local_source*]
+#   Tri-state variable that can be true, false (default) or a source path to the
+#   local Apparmor profile. If true, uses "${default_base}/local/${name}" as the
+#   source path to the local Apparmor profile. If false, do not install a local
+#   profile. If set to something else, use it as the source path.
+#
+# [*post_cmd*]
+#   The command to run after installing a profile (usually to restart a daemon).
+#   If unset (default), no command is run after installing the profile.
+#
+# === Variables
+#
+# [*lsbdistrelease*]
+#   The LSB distribution release number (normally provided as a fact).
+#
+# === Examples
+#
+# apparmor::profile { 'usr.sbin.nsd':
+#   $local_source => true,
+#   $post_cmd     => 'service nsd3 restart',
+# }
+#
+# apparmor::profile { 'usr.sbin.ssmtp': }
+#
+# apparmor::profile { 'usr.sbin.apt-cacher-ng':
+#   source => 'puppet:///modules/bar/apt-cacher-ng/aa-profile',
