Well, the documentation is certainly wrong (or not up-to-date), as the
default is actually rather '''no'''. (We decided to ''add debug symbols''
by default since that doesn't have a performance impact -- except for
larger files and hence probably slower start-up/loading, but one can strip
these symbols later. `SAGE_DEBUG=yes` in contrast does -- depending on
the spkg -- e.g. disable optimization, add extra code [probably with some
runtime overhead] , so at least ''may'' have a major performance impact.)

W.r.t. the component: I just meant changing the meaning certainly extends
to more than a documentation change (cf. the ticket's title; otherwise I'd
call it "Clarify SAGE_DEBUG", say).
Actually, what you propose is IMHO what we already have (or ''should^TM^
have'')... ;-)
So just correcting or clarifying the documentation may indeed be
sufficient. :-) (But I'd then change the ticket's title, as mentioned.)
