It's sad to realize that you cannot read what you see, yet you're
willing to lecture people on how they should do their job.


      ## Where The OpenAxiom system resides
   27 address@hidden@
   28 address@hidden@
   29 address@hidden@
   30 export AXIOM
   31 
   32 ## We adjust the value of PATH here because, currently, some OpenAxiom
   33 ## programs are called from the executing shell, and relying on the
   34 ## fact that the executables are reachable from the PATH.
   35 PATH=$AXIOM/bin:$PATH


As you can see, on line 29, the variable AXIOM is set *internally* to
the script -- therefore it does not depend on *external* setting of
the variable.  Said differently, if you set AXIOM in your shell and
execute the OpenAxiom script `axiom', the value you set in your shell
will be ignored *from within* OpenAxiom.  And the value set by OpenAxiom
does not change anything outside OpenAxiom.

This is at all opposite to Axiom, which requires manual intervention
of users to set the variable before doing anything.

Hope that helps,
