carrybasket sync tool

carrybasket is a simple tool that synchronizes data from client to server directory over IP.

Assignment description

Build an application to synchronise a source folder and a destination folder over IP:

1. a simple command line client which takes one directory as argument and keeps monitoring changes in that directory and uploads any change to its server
2. a simple server which takes one empty directory as argument and receives any change from its client

Bonus 1. optimise data transfer by avoiding uploading multiple times the same file

Bonus 2. optimise data transfer by avoiding uploading multiple times the same partial files (files are sharing partially the same content)
