Comment(by leif):
TODO:
* Add {{{PARI_EXTRA_OPTS}}}, which is passed to PARI's {{{Configure}}}
when building Sage / installing the PARI spkg.
* Add {{{CPPFLAGS}}}, {{{LDFLAGS}}}, {{{CXXFLAG64}}}?, {{{LDFLAG64}}}?
{{{LD}}}?
* Document that (e.g.) {{{export CFLAGS=""}}} has not the same effect as
{{{unset CFLAGS}}}.
* Add note on not putting a space between {{{-j}}} and {{{NUM}}} in the
description of {{{MAKE}}}, because doing so has a "completely" different
meaning...
* Add warning to (setting) {{{SAGE_CHECK}}}, since this currently breaks
most builds. This will (or should) be fixed in future releases though;
there's afaik a ticket adding more options to the value of this
variable...
* Add a note on / reference to {{{sage-env}}}.
Also, the description of some variables is incomplete, not current (in its
use in all spkgs, e.g. {{{SAGE_DEBUG}}}), misleading, or even wrong
({{{SAGE_TIMEOUT*}}}).
I think the various variations of {{{SAGE_T[E]MP[[_]DIR]}}} are missing.
(I wonder where e.g. {{{TMP}}} and {{{TMPDIR}}} are / may be used instead,
or as a fall-back / default.)
{{{SHELL}}} might be relevant, too.
The {{{*ITER*}}} variables for (parallel) doctesting are missing.
I'm currently not sure if we have a similar section in the ''Developer's
Guide'', but some variables like {{{SAGE_ROOT}}} and {{{SAGE_LOCAL}}}
should be documented (there?), too.
I'm still pretty sure even more variables are missing... ;-)
