dsync: A Backup Tool

dsync uploads modified files to a remote directory thru sftp or to a locally mounted disk. It maintains a list of modification times on the remote directory.

• dsync-1.3: Added passwd field to target configuration. Added version info. Run ./mkver.sh to update the version during build. Also run ./mkhelp.sh in order to embed the README file into the program.
• dsync-1.2: Fixed handling of big files. I now use proper stat/read pair instead of recursively reading small bits and trying to figure out the size from that.
• dsync-1.1: Added update frequency option to the configuration.
• original dsync-1.0
• preprocessed dsync-1.0
