+    # Creates a new CookbookUploader.
+    # ===Arguments:
+    # * cookbooks::: A Chef::CookbookVersion or array of them describing the
+    #                cookbook(s) to be uploaded
+    # * path::: A String or Array of Strings representing the base paths to the
+    #           cookbook repositories.
+    # * opts::: (optional) An options Hash
+    # ===Options:
+    # * :force  indicates that the uploader should set the force option when
+    #           uploading the cookbook. This allows frozen CookbookVersion
+    #           documents on the server to be overwritten (otherwise a 409 is
+    #           returned by the server)
+    # * :rest   A Chef::REST object that you have configured the way you like it.
+    #           If you don't provide this, one will be created using the values
+    #           in Chef::Config.
