Well that's a way of doing it. But it's pretty inconvenient. The shell 
lets you edit a FileSystem, XML file in place. Then of course I've got 
to test bbx_filesystem.c very rigorously because it must work, it's the 
heart of BabyXFS. So by writing the shell, I flush out any problems with it.

And of course now the fun part of the project comes in. I add MiniBasic 
to the shell, so you can run basic programs from it.

And gives the users example code to show them how to use the system.
