    // with the remote directory tree rooted at "qa/syncRemote2"

    // Possible modes that can be passed to the SyncTreeUpload method are:
    // mode=0: Upload all files
    // mode=1: Upload all files that do not exist on the server.
    // mode=2: Upload newer or non-existant files.
    // mode=3: Upload only newer files. If a file does not already exist on the server, it is not uploaded.
    // mode=4: transfer missing files or files with size differences.
    // mode=5: same as mode 4, but also newer files.

    // Because we want to see the ProgressInfo callbacks, upload all files..
