Hello again, Jeff.

Oh, you plan to release another implementation of NDN.
I want some result in about a month (not complete one is OK).

It is possible for us to write source codes in C++. We can study that
if we don't understand it enough.

I have a question about compiling source codes using CCL API for C++.
I reached a hypothesis that, when compiling (& linking), I can use the
command below:

     g++ my_source_code_1.cpp [my_source_code_2.cpp ...] <ndn-cpp-0.2

Is that right?
And do my source codes need any #include other than "#include <iostream>?"
