In its current state, Collapse OS has all you need to assemble z80 source
from within the shell. What you need is:
* A mounted filesystem with `zasm` on it.
* A block device to read from (can be a file from mounted CFS)
* A block device to write to (can also be a file).
The emulated shell is already set up with all you need. If you want to run that
on a real machine, you'll have to make sure to provide these requirements.
The emulated shell has a `hello.asm` file in its mounted filesystem that is
ready to compile. It has two file handles 0 and 1, mapped to blk IDs 1 and 2.
We will open our source file in handle 0 and our dest file in handle 1. Then,
with the power of the `fs` module's autoloader, we'll load our newly compiled
file and execute it!

> fnew 1 dest ; create destination file
> fopen 0 hello.asm ; open source file in handle 0
> fopen 1 dest ; open dest binary in handle 1
> zasm 1 2 ; assemble source file into binary file
> dest ; call newly compiled file
Assembled from the shell
> ; Awesome!
