So your idea is that you could run `rund -install prog.d` which 
would create some sort of file that allows you to run `./prog` 
(on POSIX) or `prog` (on WINDOWS).

So something like this:

/path/prog.d

Posix:
/path/prog -> /usr/bin/rund

Windows 10 (It supports symbolic links)
/path/prog.exe -> C:\Programs\rund.exe

Windows <10
/path/prog.exe (a copy of rund.exe)


Then this would allow you to run "/path/prog" and which would 
invoke rund and like you said we could take "argv[0]" and assume 
that's the main source file.

The Posix/Windows 10 cases seem fine, but Windows <10 is not 
great. In this case it has to keep an entire copy of rund around 
(currently 1.8M). I think we can do better.  Instead, `rund 
-install prog.d` could generate a little "wrapper program" that 
forwards any calls to rund.  You could make this wrapper program 
with a small D program, or with this BATCH script:

--- /path/prog.bat
@rund %~dp0prog.d %*

You get the same result. When you run "\path\prog" it will invoke 
rund with the given args for prog.d. Thoughts?
