I have read GDAL API Tutorial.
The Tutorial wrote "Once the dataset is successfully created, all
appropriate metadata and raster data must be written to the file. What this
is will vary according to usage, but a simple case with a projection,
geotransform and raster data is covered here."

If I want to write more metadata other than projection, geotransform etc,
What should I do?
I want to keep the original tiff file metadata and add my metadata to the
new create tiff.
