In my haste to plug sage-mode, I forgot this:

Here's something that happens to me: I have an object X that has a *lot* of
methods -- matrices and graphs, often -- and I'm wondering if X has a
certain method. Often, I find myself doing
X.a (look through "a" methods...)
X.b (look through "b" methods...)

Nice! Unfortunately the top link for "View Tickets" doesn't point

Can there be a "My Tickets (active, by component)" one as well?
Hopefully this will help the Trac become more organized.

Gfan does a lot more than compute the Groebner fan. My main use for
it is computing tropical prevarieties. Anders Jensen keeps improving
gfan, and in fact our interface to it doesn't wrap all the current
functionality. I think it would be quite a job to replace it.

gfan definitely depends on cddlib.
Unless it is somehow broken I would keep sage.geometry.groebner_fan
and the gfan spkg for now. In the long term we should rewrite
sage.geometry.groebner_fan to work with the new Fan class from the
toric geometry stuff. And I think it would be easy enough to take

I'm pretty sure that it does not randomize the output; certainly grep

reason to call a pseudo random number generator for the

I'd rather leave cddlib for polyhedra over RDF until there is an

I support replacing cddlib with PPL for the default computation of
exact polyhedra.
Eventually I would really like to see lrs as a standard component as
well, because:
1) It is small and compiles on all our supported platforms.
2) David Avis has always been very responsive to any emails about lrs.
Setting SAGE_CHECK=yes just means that after building the pari
library, the self-test routines are also run. It does not affect Sage
after the new spkg is installed.

The short answer is no. The PPL can work with floating point types for
