[Axiom-developer] lisp dead code

[daly]

I've been using the method of finding the root of the code tree and
walking the branches. At each branch node, the code is collected and
documented, the variables it depends on are collected and documented
and the code is reorganized.  The data structures used in the code are
documented. When this process is completed for a root node it will end
up in a package with only the exposed API functions exported.

The interpreter is gradually moving into bookvol5 and the compiler
will eventually move into bookvol6. Hyperdoc is bookvol7 and graphics
is bookvol8. What remains after the tree is walked must either contain
a new root or dead code.
