Compiling D inside of a D program

[Mineko]

This is a fairly basic question but I can't find any good 
answers, so I'm asking..

Anyways, I want to be able to invoke the D compiler, whichever 
that might be from inside of a D program, so I can say, compile a 
D script on-the-fly in some game, it's just an idea though.

To be even more to the point, how can I invoke the D compiler 
inside of a D program, also, do I need to bundle said D compiler 
with my program or does D have some compilation feature inside of 
an already compiled program (Which I doubt)?
