-------------------------+------------------------------------------
 On Linux, the start-tor-browser script checks for SSE2 support by grepping
 /proc/cpuinfo. On some systems, /proc/cpuinfo isn't readable to ordinary
 users (Whonix may implement this) so it will fail with an error saying
 "Tor Browser requires a CPU with SSE2 support.".

 It would be better if the script checked if the file is not readable and
 if it isn't, it tries to grep it with `sudo --noninteractive` so  people
 can add sudoers exceptions for the Tor Browser.
