\frametitle {The Components of SAGE: What and Why}
\begin{itemize}
\item cddlib-094b -- program to generating all vertices and extreme rays of a general convex polyhedron in $\mathbf{R}^d$ given by a system of linear inequalities (needed by gfan, but I wish it's functionality were directly exposed).
\item clisp-2.41 -- the common lisp interpreter (needed by Maxima; could be replaced by GCL, but clisp is the only {\em only} lisp that {\em really} builds everywhere)
\item conway\_polynomials-0.1 -- a database of polynomials that define finite fields (not really used -- should be used to implement natural embeddings between finite fields -- volunteers?)
\item cremona\_mini-0.1 -- Cremona's database of elliptic curves of conductor up to $10000$.
\item doc-2.1.3 -- install guide (good), tutorial (good, but needs update), reference manual (needs way more explanatory overviews and better organization), and constructions guide (needs to be updated!)
\end{itemize}
