username - Your OpenStack username or public key, depending on auth_method. required
authtenant_name OR :authtenant_id - Your OpenStack tenant name or id required. Defaults to username. passing :authtenant will default to using that parameter as tenant name.

Known limitations

Additional metadata passed on storage will have their value stored as a String

for example:

app = Dragonfly.app
content = Dragonfly::Content.new(app, "gollum")
content.add_meta('bitrate' => 35, 'name' => 'danny.boy')

will store 35 as "35"
