+###> Downloading Files: The download Method
+
+The [`download`](../yard/Rscons/Script/GlobalDsl.html#download-instance_method)
+method can be used to download a file from a given URL.
+
+Example use:
+
+```ruby
+default do

+end
+```
+
+The `download` method downloads the file specified by the URL in the first
+parameter, and writes it to the local file specified by the second parameter.
+If the `:sha256sum` option is given, this causes two changes to the default
+behavior:
+
+  * If Rscons finds the local file and it already has this checksum, then the
+    file will not be downloaded again.
+  * After downloading, Rscons verifies that the checksum matches what is given
+    and exits with an error if it does not.
