searching more efficient (such as the --fuzzy option and the
support for multiple --compare-dest options).
-Also fixes a potential synchronization problem between the generator
-and the receiver in read-batch mode. Should consider making the
-sending of the index value the default for this pipe (it's currently
-only sent in batch mode due to the sender not listening to the
-generator to determine what files get updated).

You must run "make proto" before compiling.
