Nothing should go into the standard Sage until:
(1) it has been an optional package for some nonzero amount of time,
(2) enough people have had a chance to look over the code and
try it in the context of Sage,
(3) there is enough clear demand for it.
Getting R into Sage is a high priority, but it is definitely more than
a week away, since there isn't even an R optional package yet -- only
an R experimental package -- which means that I know that the
package fails to build on some platforms, etc., and hasn't been
well tested. Regarding (2), (3), R is in very good shape.
Atlas (automatically tuned linear algebra software) -- the fast basic
numerical linear algebra library -- also satisfies (2), (3), but there
are some build issues with it too.
Regarding PolyBoRi, (1) it is now an optional package (I just added
it to the optional package list). It would be good if everybody
reading this with interest in polybori and some cycles to spare
could type
sage: install_package('polybori-0.1-r3')
and report the results. Regarding (3) it's clear there is strong
demand for PolyBoRi from several people. (2) needs to happen.
Could Burcin post a link to his patch bundle that provides library
support for PolyBoRi for Sage in this thread, so we can all try
it out? Also, regarding (2) could somebody who isn't the author
of PolyBori actually at least *skim through the code* and make
some comments about the quality, maintainability, lack-of-bad
stuff, etc.?
