+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 ':'.
