## 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 keep Tor Browser updated.
## (Thandy doesn't exist yet.)
## - 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:
