-GiNaC is a C++ library. Its design is revolutionary in a sense that contrary 
-to other CAS it does not try to provide extensive algebraic capabilities and 
-a simple programming language but instead accepts a given language (C++) and 
-extends it by a set of algebraic capabilities. 
-The name GiNaC is an iterated and recursive abbreviation for GiNaC is 
-Not a CAS, where CAS stands for Computer Algebra System. 
-
-This requires cln.

-# HOW TO EDIT THIS FILE:
-# The "handy ruler" below makes it easier to edit a package description.  Line
-# up the first '|' above the ':' following the base package name, and the '|' on
-# the right side marks the last column you can put a character in.  You must make
-# exactly 11 lines for the formatting to be correct.  It's also customary to
-# leave one space after the ':'.
