Usage:
------
Install Bitcart on this server
This script must be run as root, except on Mac OS
    -h, --help: Show help
    -p: print settings and exit
    --name name: Configure new deployment name. Affects naming of profile env files and
    startup config files. Allows multiple deployments on one server.
    Empty by default
    --install-only: Run install only
    --no-startup-register: Do not register Bitcart to start via systemctl or upstart
    --no-systemd-reload: Do not reload systemd configuration
This script will:
* Install Docker
* Install Docker-Compose
* Setup Bitcart settings
* Make sure it starts at reboot via upstart or systemd
* Add Bitcart utilities in /usr/bin
* Start Bitcart
You can run again this script if you desire to change your configuration.
Make sure you own a domain with DNS record pointing to your website.
Passing domain ending with .local will automatically edit /etc/hosts to make it work.
Environment variables:
    BITCART_INSTALL: installation template to use (eg. all, backend, frontend)
    BITCART_CRYPTOS: comma-separated list of cryptocurrencies to enable (eg. btc)
    BITCART_REVERSEPROXY: which reverse proxy to use (eg. nginx, nginx-https, none)

    REVERSEPROXY_DEFAULT_HOST: Optional, if using a reverse proxy nginx, specify which website should be presented if the server is accessed by its IP.
    BITCART_ENABLE_SSH: Gives Bitcart SSH access to the host by allowing it to edit authorized_keys of the host, it can be used for updating or reconfiguring your instance directly through the website. (Default: true)
    BITCART_SSH_PORT: Port where ssh server runs on host machine. Default: 22
    BITCART_HOST: The hostname of your website API (eg. api.example.com)
    BITCART_LETSENCRYPT_EMAIL: A mail will be sent to this address if certificate expires and fail to renew automatically (eg. me@example.com)
    BITCART_STORE_HOST: The hostname of your website store (eg. example.com)
    BITCART_STORE_API_URL: The URL to your website API (hosted locally or remotely, eg. https://api.example.com)
    BITCART_ADMIN_HOST: The hostname of your website admin panel (eg. admin.example.com)

    XRG_NETWORK: The network to run ergon daemon on (eg. mainnet)
    LTC_NETWORK: The network to run litecoin daemon on (eg. mainnet, testnet)
    LTC_LIGHTNING: Whether to enable litecoin lightning network or not (eg. true, false)
    BSTY_NETWORK: The network to run globalboost daemon on (eg. mainnet, testnet)
    BSTY_LIGHTNING: Whether to enable globalboost lightning network or not (eg. true, false)
    GRS_NETWORK: The network to run groestlcoin daemon on (eg. mainnet, testnet)
    GRS_LIGHTNING: Whether to enable groestlcoin lightning network or not (eg. true, false)
    XMR_NETWORK: The network to run monero daemon on (eg. mainnet, testnet)
    BITCART_ADDITIONAL_COMPONENTS: A list of additional components to add
    BITCART_EXCLUDE_COMPONENTS: A list of components to exclude from the result set
    BITCART_HTTPS_ENABLED: a special flag to rewrite bitcart API URLs to https. It does not enable https setup automatically and is required for custom cases such as cloudflare tunnel.
    BITCART_BEHIND_REVERSEPROXY: set this when running in one domain mode with custom nginx port, but when bitcart's nginx is behind your own reverse proxy
Add-on specific variables:
    TOR_RELAY_NICKNAME: If tor relay is activated, the relay nickname
