This starts the file synchronisation service, used to implement "adb push"
and "adb pull". Since this service is pretty complex, it will be detailed
in a companion document named SYNC.TXT
+
+reverse:<forward-command>
+ This implements the 'adb reverse' feature, i.e. the ability to reverse
+ socket connections from a device to the host. <forward-command> is one
+ of the forwarding commands that are described above, as in:
+
+ list-forward
+ forward:<local>;<remote>
+ forward:norebind:<local>;<remote>
+ killforward-all
+ killforward:<local>
+
+ Note that in this case, <local> corresponds to the socket on the device
+ and <remote> corresponds to the socket on the host.
+
+ The output of reverse:list-forward is the same as host:list-forward
+ except that <serial> will be just 'host'.
