Adding the possibility to specify the unless condition manually

[apazga]

This way users can add their specific condition (not just if the file exist or need to be replaced)

E.g. thinking about the possibility, to automatically download the latest version of Wordpress in the VirtualHost directory just if the directory if empty (and, e.g., if it already have been deployed/uncompressed, I don't want wget to download it anymore).

wget::fetch { 'wget_wordpress':
    source      => 'https://wordpress.org/latest.tar.gz',
    destination => "$webserver_wwwroot/latest_wordpress.tar.gz",
    timeout     => 0,
    unless      => 'test "$(ls -A . 2>/dev/null)"',
  }

Can you add some docs, tests?

+1 for this. Also, a 'refreshonly' capability would be awesome.

After some tests, new pull request sent. README.md updated too with an example. Hope it helps.
