It all comes done to one thing, the "source" function. If you launch an 
application in a shell that application can't set environment variables 
that will be available to the shell when the application exits.

So instead I have most of the application written in D with a bash 
function that wraps the application. It works like this:

1. The function calls the D application
2. The D application performs all it needs to and writes a shell script 
to a file
3. The bash function calls "source" with this file as a parameter
