to exit when you are done. Beware:
* Do not do anything with other copies of Sage on your system.
* Do not use this for installing Sage packages using "sage -i" or for
running "make" at Sage's root directory. These should be done
outside the Sage shell.
Bypassing shell configuration files...

}}}
Consequence : some packages, which need Rscript for installation (because
they try to download some library source tarballs) can no longer be
installed in R. This include notoriously nloptr, on which lme4 (a mixed-
model package ofextremely frequent use) and other often-used packages
depend.
Consequence of this consequence : Sage no longer offers a *replacement*
for system's R. Ouch !
