Actually as I understand it Silver is supposed to be the
"release candidate" for Axiom Gold. But as Gaby stated in such
an eloquent circumlocution: "We seem to have communications
problems." The procedure as set out by Tim Daly is not really
working and it seems that he is continuing on his own to
manually incorporate some of the changes now in the build-
improvements and wh-sandbox branches, effectively bypassing
the "Silver" stage. This might result in a new "Gold" but
it's pedigree will still be rather uncertain.

wh-sandbox has implemented a radically different algebra build
process that avoids many of the problems associated with the
old "bootstrap" method. It has also implemented some significant
improvements to the way the Axiom database is built. Therefore
it is not clear to me if it would be possible to incorporate
Martin's package in the old Silver release without first
incorporating most (if not all) of the changes in wh-sandbox.
Silver is essentially just the old patch-50 from the tla
archives. You will recall the problems that we had last summer
trying to get Martin's code built on that system.

One could proceed by backporting all (or most) of the revisions
from the build-improvements branch and the wh-sandbox sub-
branch, but that would certainly be a lot of work! I think the
state of the current /silver branch (almost the same as /trunk)
on SourceForge is too distant from both build-improvements and
wh-sandbox branches to continue to serve as the base. It would
much better just to re-define it as something very close to the
current wh-sandbox (or build-improvements with wh-sandbox
