## Module description

puppetlabs-rsync manages rsync clients, repositories, and servers as well as
providing defines to easily grab data via rsync.

## Usage

Install the latest version of rsync
~~~puppet
class { 'rsync': 
  package_ensure => 'latest' 
}
~~~

Get file 'foo' via rsync
~~~puppet
rsync::get { '/foo':
  source  => "rsync://${rsyncServer}/repo/foo/",
  require => File['/foo'],
}
~~~

Put file 'foo' on 'rsyncDestHost'
~~~puppet
rsync::put { '${rsyncDestHost}:/repo/foo':
  user    => 'user',
  source  => "/repo/foo/",
}
~~~

Setup default rsync repository
~~~puppet
rsync::server::module{ 'repo':
  path    => $base,
  require => File[$base],
}
~~~

To disable default values for `incoming_chmod` and `outgoing_chmod`, and
do not add empty values to the resulting config, set both values to `false`

~~~puppet
rsync::server::module { 'repo':
  path           => $base,
  incoming_chmod => false,
  outgoing_chmod => false,
  require        => File[$base],
}
~~~

#### Configuring via Hiera 
`rsync::put`, `rsync::get`, and `rsync::server::module` resources can be
configured using Hiera hashes. For example:

~~~yaml
rsync::server::modules:
  myrepo:
    path: /mypath
    incoming_chmod: false
    outgoing_chmod: false
  myotherrepo:
    path: /otherpath
    read_only: false
~~~
