The NDK is an Nginx module that extends the core functionality of the
Nginx webserver in a way that can be used as a basis for other Nginx
NDK has functions and macros to deal with tasks that do not currently
have code in nginx. NDK itself adds few features that are seen by
end-users; the plan is to reduce the code that module developers need
Using features from the NDK makes it a dependency that users will
need to install as well.
