I think savannah does have such plans.  Maybe we should wait until
they are implemented.

     Do you mean a real linked list or the kind of dynamic vector that
     subclist currently implements?  The properties are quite
     different.  I have an actual linked list ADT in the works but
     it's not ready yet.  If you'd like a dynamic vector, sounds fine
     to me.

Actually I'd forgotten how I implemented it.   The properties are
indeed different, but the differences only become significant when 
there are are lots of elements.   In it's current use, there's never
going to be a subclist which contains lots of elements.  But you're
right I should have thought about it more carefully.  If you're
cooking up a linked list, then I'll wait until it's ready.

     I was hoping to put only implementations of commands in
     commands/, but the suggestion does sound reasonable.

and all of the files in math are indeed (part of) implementations of
commands.

     A procedure processes the active file, a utility does not.

When you say "processes", should I infer "modifies"?  Nearly all of
the commands depend upon the active file in some way.
