Simple I know, but could use some help compiling with make

What rdmd does is takes the file with "main()", figures out all the ".d" 
files needed, checks if any of them have been changed, and if so, it sends 
them all to dmd to be compiled. If you omit the "--build-only" it will also 
run the program you built. The full format for rdmd is:

rdmd {params for dmd and rdmd} main.d {params for main.exe}

So if you have:

//main.d
import std.stdio;
void main(string[] args)
{
    writeln("Hello", args[1]);
}

Then you can do this:

> rdmd main.d Joe
Hello Joe

It's an awesome tool. You can run just "rdmd" by itself to see all it's 
options.

Be aware though, rdmd has some issues if you're not using at least DMD 
2.055.
