I've already figured out one way to do it (the code I included with my
original message is the basic technique). What I really want to know
is how the library works and how to avoid pulling in a lot of what
should be unnecessary library code. Forking a new process is even
worse for me than that!

I believe that my code pretty much does what the Line Mode browser
would do in the case of "-source".
