Tor Browser Launcher is intended to make Tor Browser easier to
install and use for GNU/Linux users. You install
torbrowser-launcher from your distribution's package manager and
it handles everything else:

- Downloads and installs the most recent version of Tor Browser
in your language and for your computer's architecture, or
launches Tor Browser if it's already installed (Tor Browser
will automatically update itself)
- Certificate pins to https://www.torproject.org, so it doesn't
rely on certificate authorities
- Verifies Tor Browser's signature for you, to ensure the
version you downloaded was cryptographically signed by Tor
developers and was not tampered with
- Adds "Tor Browser" and "Tor Browser Launcher Settings"
application launcher to your desktop environment's menu
- Apparmor profile to limit effect of Tor network compromise
