Marek Habersack has contributed (and maintains) C++ wrappers installed to
`include/ncpp/`, `libnotcurses++.so`, and `libnotcurses++.a`.
In their default mode, these wrappers never throw exceptions. If
`NCPP_EXCEPTIONS_PLEASE` is defined prior to including any NCPP headers,
they will throw exceptions.
In their default mode, these wrappers throw exceptions only from the type
constructors (RAII). If `NCPP_EXCEPTIONS_PLEASE` is defined prior to including
any NCPP headers, they will throw exceptions.
