OK, sorry for being a smart-ass. Can't help it sometimes!
Basically, the app knows its home directory, and creates a list of
all the files and their timestamps. It sends that to the server, which
does the same, and compares the two. If there is no difference, we're
done. If there are any changes, the servers zips up just those changes
into a temp file, and sends the name of that file back to the client.
The client responds by downloading the file and unzipping it to bring
it up to date. For lightweight files, such as .py scripts and .cdxml
UI files, the whole process happens as fast as you can load a typical
web page in a browser.
