Successful first run of B interpreter!
...
I hand compiled hello.b into hello.s and assembled with the interpreter
and runtime library:
perl as7 --out a.out bl.s hello.s bi.s

a7 is updated with Phil's stdin reading patch. I've written a few more
...
utilities and modified the v1 man pages for them. Fixed a typo (missing
line) in src/cmd/as.s.

Based on the details of the directory structure that Phil found, I've
...
modified the a7out and the wktls.s program to reflect this.

I added smes and rmes system calls to a7out and wrote some code
...
in src/other/fork_test.s to test it. It's not working quite right
yet, we keep getting wait() returning -1 in a7out even though there
is a child process.

I've added fork() to a7out after adding some comments to src/cmd/init.s.
...
There is a test program to demonstrate fork working.

I've moved these working programs into the src/other folder as they are
...
not strictly tools.
