Current limitation include:
28
* Metadata format is not stable yet -- you may need to
29
discard history in the future.
31
* No handling of subdirectories, symlinks or any non-text files.
33
* Insufficient error handling.
35
* Many commands unimplemented or partially implemented.
37
* Space-inefficient storage.
39
* No merge operators yet.
