These 4 files can be used on the remote systems to update the target tree
using the --read-batch option. This is more efficient because the transfer of
the diff information can happen in parallel (e.g. using multicast filetransfer
tools) and the source tree is only examined once instead of N times. Of
course, this only works if the target trees are not changed in any other way
than by using this method.
