[Axiom-developer] changes

[root]

*,

manexp, acot, and get-current-directory lisp functions added (Juergen)
mnt/linux/doc/DeveloperNotes.dvi is now a dvi file (Camm)
head and tail are now boxhead, boxtail (Bill)
the startup msgs are cleaner (me)
summary, copyright exist and work (Camm, David)
more input tests run (me)
rename r2.*.input.pamphlet to r2*.input.pamphlet (me)
expanded README (Camm)
removed Makefile.dvi (Camm)
added RSDCMPK, INTRVL, ODEEF (Juergen, David)
added Clef (Bill)
expanded DeveloperNotes (me)

clef still needs to be enabled. To do that I have to change
axiom to a shell script and that isn't done yet.

A couple of the input files are still failing. Check 
src/input/Makefile.pamphlet and look for VALUESTACK.

Virtually all of the MANEXP failures are now errors of the form:
Error: (7) is not of type NUMBER
which leads me to believe that the MANEXP definition is somewhat amiss.

The GET-CURRENT-DIRECTORY bug has been solved.
The ACOT bug has been solved but now COT is undefined.

ODEEF's test file ode.input fails


I'll check these changes in soon. I want to rebuild from scratch
once more to make sure they work. Paranoia, yaknow?
