S3 Form Presenter
Generates a simple form that is compatible with S3's form API. You can upload S3 assets directly to S3 without hitting your server.
Usage
<% S3FormPresenter::Form.new("some/key/path.ext", "http://www.theredirecttowebsite.com/redirect/to/this/path") do %>
<input name="file" type="file">
<input type="submit" value="Save File">
<% end %>
