// TODO:
// * FindNCurses needs to remove the old probing code
// * Removal of that proxy code
// * Need to implement reading pointers with the new API
// * Can remove the manual Dlopen features
// * initscr() diagnostics based on DLL can be fixed
//
// binding.cs.in: Core binding for curses.
//
// This file attempts to call into ncurses without relying on Mono's
// dllmap, so it will work with .NET Core.  This means that it needs
// two sets of bindings, one for "ncurses" which works on OSX, and one
// that works against "libncursesw.so.5" which is what you find on
// assorted Linux systems.
//
// Additionally, I do not want to rely on an external native library
// which is why all this pain to bind two separate ncurses is here.
