# DESCRIPTION
# This script installs the newest version of TorBox on a clean, running
# Debian System (Tested with Bookworm).
#
# SYNTAX
# ./run_install.sh [-h|--help] [--randomize_hostname] [--select-tor] [--select-fork fork_owner_name] [--select-branch branch_name] [--on_a_cloud] [--step_by_step]
#
# The -h or --help option shows the help screen.
#
# The --randomize_hostname option is helpful for people in highly authoritarian
# countries to avoid their ISP seeing their default hostname. The ISP can
# see and even block your hostname. When a computer connects to an ISP's
# network, it sends a DHCP request that includes the hostname.
#
# The --select-tor option allows to select a specific tor version. Without
# this option, the installation script installs the latest stable version.
#
# The --select-fork option allows to install a specific fork. The
# fork_owner_name is the GitHub user name of the for-owner.
#
# The --select-branch option allows to install a specific TorBox branch.
# Without this option, the installation script installs the master branch.
#
# The --on_a_cloud option has to be used if you install TorBox on a cloud or
# as a cloud service. This will enable/disable some features.
#
# The --step_by_step option execute the installation step by step, which
# is ideal to find bugs.
#
# IMPORTANT
# Start it as root
