           Do not overwrite existing map

       --overwrite
           Allow output files to overwrite existing files

DESCRIPTION

       r.mapcalculator provides a GUI frontend to r.mapcalc.   Up  to  5  maps  can  be  combined  using  simple
       expressions.   In  the  expert  mode, it runs r.mapcalc for more complex expressions.  Enter an r.mapcalc
       expression in the formula field using the format: A+C or exp(A+C)+(B-2)*7 where A, B, C are  raster  maps
       entered in the A field, B field, and C field.

       Do  not  enter output file in the formula field: correct: A+B; incorrect: newfile = A+B. Use no spaces or
       blanks.

       Expert mode runs r.mapcalc for more complex expressions.
