DSync is a dead-simple P2P file synchronization tool using the SSH protocol.
The synchronization is 2-way, and the algorithm used to determine the correct version to use simply just looks at the mtime (last modified time) of a file on both ends, and the one with the later one gets synchronized to the other side.
To build, simply run:
go build ./cmd/dsyncTo run, execute the resulting file, or the following command directly:
go run ./cmd/dsync
