/* Tox Sync
|
|
*
|
|
* Proof of concept bittorrent sync like software using tox, syncs two directories.
|
|
*
|
|
* Command line arguments are the ip, port and public_key of a node (for bootstrapping) and the folder to sync.
|
|
*
|
|
* EX: ./test 127.0.0.1 33445 CDCFD319CE3460824B33BE58FD86B8941C9585181D8FBD7C79C5721D7C2E9F7C ./sync_folder/
|
|
*
|
|
* NOTE: for security purposes, both tox sync instances must manually add each other as friend for it to work.
