Writing a library

[Mn]

Hello World!

Is it possible to write a library in D that can be used by other programming languages? And if yes, how to do it? I can think of two ways of "using" a lib in general:

1. The OOP way: use a class of the lib, then its functions, dunno how its called.
2. The Un-OOP way: use a function of a lib, its called P/Invoke in C#.

I am only interested in the more popular languages like C, C++, Java, C#, PHP.

Greetings and thank you.
