    ; Possible synchronization modes are:
    ; mode=0: Download all files
    ; mode=1: Download all files that do not exist on the local filesystem.
    ; mode=2: Download newer or non-existant files.
    ; mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server..
    ; mode=5: Download only missing files or files with size differences.
    ; mode=6: Same as mode 5, but also download newer files.

    ; Imagine our remote directory tree has these files and directories:

    ; 	text/frenchUtf8.txt
    ; 	text/helloWorld.txt
    ; 	text/PolishEmailBody.txt
