Comment (by lazaa):

 Replying to [comment:1 wenzeslaus]:
 > I think the size should be specified in map units, for example user can
 say `size=250` to get 250m scale bar. This seems like a simple and
 actually a desired option. What are the units there probably depend on the
 rest of the implementation or interface of d.barscale. With the current
 implementation it would be probably meters by default but it should be
 feet when the `-f` is used.

 I added option{{{length}}}, so the size can be specified in map units. By
 defaults in meters, with {{{-f}}} flag in feet. I'm not sure it's the best
 solution. If user wants a barscale of size let's say 150 miles he has to
 convert 150 miles into feet.
