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)
* Verifies Tor Browser's [signature](https://www.torproject.org/docs/verifying-signatures.html.en) for you, to ensure the version you downloaded was cryptographically signed by Tor developers and was not tampered with
