Re: Alpha Backend

I should add a note to Marcs's memo on what Alpha is.  While alpha-1 does
indeed support documents & links semantics, it does so as a frontend
function.  There is a library in alpha-1/febe/FeBe-sto.o which contains
all of these functions.  The FeBe library consists of what we have been
calling the "middle end," and will be in large part pushed into the backend
for performance reasons--notably to reduce the number of frontend transactions
that require operating system service for the socket.  As a separate
module, Markm and the frontend crew can tinker with the Docs & Links stuff
without having to relink the rest of the backend all the time.
