@C Assume an input dataset having three parameters with the names geosp, t and tslm1.
@C To print the description of these parameters use:
@C @BeginVerbatim
@C    cdo pardes ifile
@C @EndVerbatim
@C Result:
@C @BeginVerbatim
@C    129  geosp         surface geopotential (orography) [m^2/s^2]
@C    130  t             temperature [K]
@C    139  tslm1         surface temperature of land [K]
@C @EndVerbatim
Assume all variables of the dataset are on a Gausssian N16 grid.
To print the grid description of this dataset use:
@BeginVerbatim
   cdo griddes ifile
@EndVerbatim
