Thanks. Is there a way to use a D library without having access 
to it's source code? I tried `dmd -lib abcd.d` which creates a 
static library. But still I need to specify path to library's 
source files using -I option when compiling the code that uses 
that library.

So if we have just access to the library file, is it possible to 
use it in the code?
