+
+Options:

+ -y Assume defaults for all questions.
+
+ -s <seconds>
+ Sleep given amount of seconds before invoking firmware burn.

+
+ -u <url>
+ Fetch firmware image from given url. A file "md5sums" is expected
+ in the same remote directory. If there is no such file, use -v to
+ suppress verification.
