Comment:

 Hi,

 I have now added a new "units" instruction to the ps.map scalebar.
 Everything should be obvious and automatic.
 You get a nice label too.


 usage:
   units      auto|meters|kilometers|feet|miles|nautmiles

 the default is auto in which case it grabs the units label from
 PROJ_UNITS.


 example:

 {{{
 # spearfish dataset
 ps.map out=test.ps << EOF
 raster elevation.dem
 scalebar f
   length 4
   units nautmiles
   height 0.15
   where 3 7
   end
 grid 1852
   end
 end
 EOF
 }}}


 thanks to Alessandro Frigeri for figuring out the label placement.
