+  <longdescription>
+ SymPy is a Python library for symbolic mathematics (manipulation). It
+ aims to become a full-featured computer algebra system (CAS) while keeping
+ the code as simple as possible in order to be comprehensible and easily
+ extensible. SymPy is written entirely in Python and does not require
+ any external libraries, except optionally for plotting support.
