What are my obligations when using libcurl in my commerical apps?

Next to none. All you need to adhere to is the MIT-style license (stated in the COPYING file) which basically says you have to include the copyright notice in "all copies" and that you may not use the copyright holder's name when promoting your software. You do not have to release any of your source code.

You do not have to reveal or make public any changes to the libcurl source code. You do not have to reveal or make public that you are using libcurl within your app. As can be seen here: curl.haxx.se/docs/companies.html and elsewhere, more and more companies are dicovering the power of libcurl and take advantage of it even in commercial environments.

More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
