of symbolic expressions.
It currently provides the backend for symbolic expressions in SageMath.

+Pynac -- "Python is Not a CAS" is a modified version of Ginac that
+replaces the depency of GiNaC on CLN by a dependency instead of Python.
+It is a lite version of GiNaC as well, not implementing all the features
+of the full GiNaC, and it is *only* meant to be used as a Python library.
