Bill,

re: the main branch

The axiom--main--1 branch needs a minor change to the axiom script
to make it start sman rather than AXIOMsys. There are a bunch of
options to sman which I need to document (in the sman.pamphlet).
Once the 'axiom' script calls sman rather than AXIOMsys the graphics
is always available.

I've attached the original form of the axiom command which we are
incrementally approaching. The current axiom command needs to pick
up the parts that handle the graphics options.

We also have to go into the input/Makefile.pamphlet and enable the
test cases which use graphics. These test cases should work but they
need testing. I believe most of them are under the 'SKIP' list
(around line 6420) in the Makefile.pamphlet

I also have been working with the CRC Handbook of Curves and Surfaces
making new test cases by drawing the graphs shown there. Axiom can draw
up to 9 graphs on the same image. I can reproduce some of the examples
but more needs to be done. It is basically tedious testing. I've found
one bug and I'll post it when I get a chance.
