instructions for Debian

- Move btsync to "/usr/bin" or replace DAEMON with the absolute path to btsync
- Copy the script to "/etc/init.d" and "chmod +x" it
- Replace BTSYNC_USERS with a list of usernames that you want btsync to work with, space delimited
- Use "update-rc.d xbt-tracker defaults" to make the service btsync start at system initialization

- Create a directory named ".sync" in each home directory
- Create a file inside ".sync" named "config.json" with the dumped and modified configuration
- Replace the configuration entry "storage_path" with the path to the ".sync" directory

>>> WHEN SETTING UP BTSYNC FOR MULTIPLE USERS, REMEMBER TO USE DIFFERENT PORT NUMBERS FOR webui.listen - MULTIPLE PROCESSES CAN'T LISTEN TO THE SAME PORT! <<<

- Execute "/etc/init.d/btsync start"

Example:

{
  "device_name": "<DEVICE NAME>",
  "listening_port": 0,
  "storage_path": "/home/btsync/.sync",
  "check_for_updates": true, 
  "use_upnp": true,
  "download_limit": 0,                       
  "upload_limit": 0, 
  "webui": {
    "listen": "0.0.0.0:8888",
    "login" : "admin",
    "password" : "password"
  },
  "shared_folders": []
