[gdal-dev] Creation/read format question

Hi Tyler,

'ro' and 'rw' mean what they imply.

The '+' symbol tells that the format supports the Create() method. So, we
can use them to create a dataset from scratch and add metadata explicitly.
Without it, we need a 'template' dataset.

The 'v' means that the format driver supports the virtual system interface.
Note that there may be drivers that support it but don't report that they
