How do you plan to add examples for python/php/gimp? As far as I know,
we don't support those languages directly.

I'm for option D. Users will have to adapt the examples to their own
environment, also documenting the required conversions will be useful.
Providing a C++ example using a C++ toolkit seems a good option.

I don't think maintaining duplicated code for C/C++ is a good idea as
I don't want to keep in synch C and C++ code, maintaining C examples
alone is enough work already, and we will end up with unsynched code
(C and C++ versions working differently).

Option A could be also be acceptable, but in the end we will need to
add more than 6 lines (for example for supporting C constructs not
supported in C++), and that will increase examples complexity even
more.
