Ok, next question:  If I wanted to run some D stuff under
the Apache web server in embedded mode I would have to
be able to write some C code which calls into D code.
This topic is not discussed in the docs that I can find.

Is it possible to call from C into D (to embedded D code into
a larger process written in C)?  You can't do this in java
and this is one of the reasons I always was averse to java
from the beginning.

Thanks again, -- Aaron Watters

you need to create the header files by hand but you can call from C code 
to D functions that are extern(C).

You may also want to initialize the D runtime.

An example of that for D2 can be found here:
http://www.digitalmars.com/d/2.0/windows.html

or for D1:
http://www.digitalmars.com/d/1.0/windows.html

Even though you aren't writing a Windows application, you should
probably write some kind of "extern(C) init() {...}" function that your
Apache code would call and thus set up the runtime.
