------------------------------------+-------------------
 The default of "DirCache 1" causes all (two) consensus versions to be
 downloaded when the typical client use on a mobile phone only requires one
 version.
 Either set DirCache automatically depending on the given configuration
 options or add a GUI option with a default of 0.
 Note that most users of orbot will probably not thoroughly read the orbot
 man page, have a look at the source code and then use the custom torrc
 option, thus superfluous data will be downloaded which is not so nice with
 a mobile data plan.
