Re: change the base of the Log[] used by LogLogPlot?

The only difference the base would make would be the required adjustment of the ticks. Any base would result in an identical plot; so use the default.

Partition[Plot[Log[#, x], {x, .1, 1},
     Frame -> True, Axes -> False,
     Epilog ->
      Text[Style["base = " <> ToString[#], 14],
       {.7, Log[#, .2]}]] & /@
   {E, Pi, 10, RandomReal[{2, 500}]}, 
  2] //
 Grid

=============
Mathematica experts:

I want to use LogLogPlot, say as in LogLogPlot[x,{x,.1,1}], but I want 
the Log to be in base 10, not in base e as the default used.

Looking at the doc, I can't see it. No option to change the base.

I can ofcourse build my own data, and use ListPlot, but LogLogPlot 
handles the ticks better automatically and it samples better. Same 
question applies for LogPlot, LogLinearPlot, ListLogPlot, 
ListLogLinearPlot, etc...

I am sure this is hidden somewhere in the documentation :)
