[PATCH] Compressed output files
Attached is a patch that implements compressing output files as they're
written to disk, uzing zlib. Thus far I've only used it with
synchronizing directories on a single machine.
What seems to work / what's done:
- Synchronizing directories with all files in the target
directory gzip'd. Files seem to contain the correct data. Use
the option "--gzip-dest".
