 Replying to [comment:13 jdemeyer]:
 > I think one should add a note in the documentation about how much disk
 space this is expected to use.  Are the spkgs first all built and then all
 deleted or are they built-deleted one by one?

 I've modified the documentation to try to address this.  I built Sage on
 various machines (sage.math, David Kirkby's machine hawk, various skynet
 machines), and found that

  - the single largest subdirectory of "build" can be up to 1165M (building
 eclib on the skynet machines iras and cleo, ia64 processors).  On all of
 the other machines, it took at most 880M.  On sage.math, cicero, and my
 mac, the largest took 320M.

  - the total amount of disk space, if you keep all of the subdirectories
 can be as large as 5.3G (iras and cleo again) or as small as 2.2G (hawk).

 I've put in conservative estimates for these in the documentation.
