Command Line Application in D

[TJB via Digitalmars-d-learn]

I am trying to build some simple command line applications that I 
have written in python as a way to learn D. Can you give some 
examples for me? For instance, I think I remember once seeing 
somewhere in the documentation an example that took several D 
files and compiled them all by running some kind of system 
command.

I much appreciate your help!
