| Truncated stream. |
| |
| Takes a stream and presents a stream that is a slice of the original stream. |
| This is used when uploading media in chunks. In later versions of Python a |
| stream can be passed to httplib in place of the string of data to send. The |
| problem is that httplib just blindly reads to the end of the stream. This |
| wrapper presents a virtual stream that only reads to the end of the chunk. |
