**WARNING: THIS IS AN UNSTABLE DEVELOPMENT VERSION**

26
Current limitation include:
27
28
* Metadata format is not stable yet -- you may need to
29
discard history in the future.
30
31
* No handling of subdirectories, symlinks or any non-text files.
32
33
* Insufficient error handling.
34
35
* Many commands unimplemented or partially implemented.
36
37
* Space-inefficient storage.
38
39
* No merge operators yet.
