Issue #448 has been updated by Luke Kanies.
And here's the doc brief I added to the commit:
You can now specify relationships directly in the language:
<pre>
File[/foo] -> Service[bar]
</pre>
Specifies a normal dependency while:
<pre>
File[/foo] ~> Service[bar]
</pre>
Specifies a subscription.
You can also do relationship chaining, specifying multiple
relationships on a single line:
<pre>
File[/foo] -> Package[baz] -> Service[bar]
</pre>
Note that while it's confusing, you don't have to have all
of the arrows be the same direction:
<pre>
File[/foo] -> Service[bar] <~ Package[baz]
</pre>
This can provide some succinctness at the cost of readability.
You can also specify full resources, rather than just
resource refs:
<pre>
file { "/foo": ensure => present } -> package { bar: ensure => installed }
</pre>
But wait! There's more! You can also specify a subscription on either side
of the relationship marker:
<pre>
yumrepo { foo: .... }
package { bar: provider => yum, ... }
Yumrepo <| |> -> Package <| provider == yum |>
</pre>
This, finally, provides easy many to many relationships in Puppet, but it also
opens
the door to massive dependency cycles. This last feature is a very powerful
stick,
and you can considerably hurt yourself with it.
