------------------------------+------------------------------------------
 As of version 60.4.0, users of Tor Browser for Android (Alpha) can no
 longer use a custom Torrc.  This is related to the fact that Tor Browser
 for Android (Alpha) no longer depends upon Orbot, which as of version
 16.0.5-RC-2-tor-0.3.4.9 continues to support this feature faithfully.

 Tor Browser for Android (Alpha) has a new startup screen that resembles
 Orbot.  On this screen, there is a "hamburger" menu in the top right
 corner that has a dropdown menu containing an option "Settings" which,
 just like Orbot, contains an option called "Torrc Custom Config".
 However, unlike Orbot, lines entered herein are not copied to
 {{{app_bin/torrc.custom}}} and (presumably thus) have no effect.

 '''TO REPLICATE'''

 1. Install both Orbot 16.0.5-RC-2-tor-0.3.4.9 and Tor Browser for Android
 (Alpha) 60.4.0 side by side.

 2. Start Orbot; from the hamburger menu choose Settings; then choose Torrc
 Custom Config.  Enter some valid line (such as {{{ControlPort 9051}}})).

 3. Open a terminal on your android device and run:
 {{{
 # cat /data/data/org.torproject.android/app_bin/torrc.custom
 }}}

 4. Verify that your custom line appeared successfully.

 5. Now start Tor Browser for Android (Alpha); from the hamburger menu
 choose Settings; then choose Torrc Custom Config.  Enter some valid line
 (such as {{{ControlPort 9151}}})).

 6. Open a terminal on your android device and run:
 {{{
 # cat /data/data/org.torproject.torbrowser_alpha/app_bin/torrc.custom
 }}}

 7. Verify that your custom line did '''NOT''' appear.
