Reviews Needed: cln, GiNaC

[Quentin Spencer]

These two packages are in CVS and need final approval. The cln library 
is used by GiNaC. The best way to test these two packages is to build 
them both and then run ginsh from the GiNaC-utils package.

cln (Class Library for Numbers):
A collection of C++ math classes and functions, which are designed for 
memory and speed efficiency, and enable type safety and algebraic syntax.

GiNaC
GiNaC (which stands for "GiNaC is Not a CAS (Computer Algebra System)") 
is an open framework for symbolic computation within the C++ programming 
language. This package includes ginsh ("GiNaC interactive shell") which 
provides a simple and easy-to-use CAS-like interface to GiNaC for 
non-programmers, and the tool "viewgar" which displays the contents of 
GiNaC archives.
