[Nishith Maheshwari]

Hi all,
Please find the following proposal for 'Integration of cpp GDAL utilities
into GDAL core library'. The same has been submitted to google-melange
website-

https://docs.google.com/document/d/1Knld8FjWCMpibF2MzJKjZ0S8mrUKdxpA7RrlUX-B95g/edit?usp=sharing

Sorry for the delay in putting up the proposal. Feedback and comments would
be really helpful.

Regards,
