(nwl) Re: [gdal-dev] Saving data to the TEXT domain NITF

[Kurt Landrus]

How hard would it be to add support, is there a lot that needs to be  
added to the framework, or is there just code that needs to be added
to the nitf driver itself?  i.e. is the code required straightforward  
enough that I can look at adding it and uploading changes?
Any tips on where I can start looking at this?
Thanks;
