-------------------------------------------------------------

Another snag though easier to fix is that currently we don't support arrays for these. For
example using the ntp module...

{code}
ntp.servers=10.0.0.1
{code}

Works expanding to:
{code}
class {'ntp':
  servers => '10.0.0.1',
}
{code}

But there is no way to give an array.

{code}
ntp.servers=[10.0.0.1, 10.0.0.2]
#or
ntp.servers=10.0.0.1, 10.0.0.2
{code}

Expands to:

{code}
class {'ntp':
  servers => '[10.0.0.1, 10.0.0.2]',
}

#or

class {'ntp':
  servers => '10.0.0.1, 10.0.0.2',
}
{code}

We probably should either:

# take csv and convert to {{["foo", "bar", "baz"]}} though it makes single element arrays
annoying
# do no quoting and the user specifies the exact string to be used

I'm for 2 since its easier, more general and probably less error prone.

> As a user of Whirr, I'd like to be able to use puppet scripts (manifests, modules) from
within Whirr to set up machines and clusters, because there are a lot of OS-neutral capabilities
and a large number of actively maintained scripts which I could benefit from.
