@Class     = Climate index
@Arguments = ifile ofile
@Operators = eca_sdii

@BeginDescription
Let @file{ifile} be a time series of the daily precipitation amount RR, then the mean 
precipitation amount at wet days (RR > @math{R}) is written to @file{ofile}. 
@math{R} is an optional parameter with default @math{R} = 1 mm.
The date information of a timestep in @file{ofile} is the date of
the last contributing timestep in @file{ifile}.
