## Developer comment on this script:
## I would be very happy if this script would not be required.
## Unfortunately, it is required. It works around a lot bugs:
## - There is no deb/rpm/whatever package with Tor Browser.
## https://trac.torproject.org/projects/tor/ticket/5236
## https://trac.torproject.org/projects/tor/ticket/3994
## - There is no way to add the Documentation page well visible to Tor Browser:
## https://trac.torproject.org/projects/tor/ticket/6025
## https://trac.torproject.org/projects/tor/ticket/6053
## - Tor Browsers support for Isolating and Transparent Proxies is very limited:
## https://trac.torproject.org/projects/tor/ticket/5611
## - RecommendedTBBVersions format is not finalized
## https://trac.torproject.org/projects/tor/ticket/14383
## - counter downgrade / stale mirror attacks on RecommendedTBBVersions - sign / verify tbb versions file
## https://trac.torproject.org/projects/tor/ticket/13065
## - GETINFO consensus/packages exists but not yet populated.
## https://trac.torproject.org/projects/tor/ticket/10395
## - Using torbrowser-launcher instead of tb-updater in Whonix
## https://forums.whonix.org/t/using-torbrowser-launcher-instead-of-tb-updater-in-whonix/385
