Hi,

I would like to propose again that we deprecate the

         sage -upgrade

functionality for "normal end users".   It was definitely never
meant to be used by anybody but developers -- in fact I wrote
it mainly for David Kohel (an early Sage developer) who lived
in Australia and consequently had severely capped bandwidth.

My proposal is that

     sage -upgrade

displays a message about upgrade in place not being implemented.
Then there is a command

    sage -devel_upgrade

(or something) that does the same thing as the current upgrade.  However,
it is only to be used by people that really know something about building
Sage and some of the issues that inevitably arise in building package from
source, etc.

Thoughts?

I think the normal upgrade procedure is best done by:

   (1) people download a completely new copy of Sage -- this is what
most software,
e.g., vmware, Parallels, etc. that I use on my Mac does, or

   (2) for Linux as we get Sage into repositories and building in a
non-monolithic way,
Sage upgrades just go through the normal apt/rpm package management system, or

   (3) we do something involving rsync and binaries (???)
