%description

Maxima is a full symbolic computation program.  It is full featured
doing symbolic manipulation of polynomials, matrices, rational
functions, integration, Todd-coxeter, graphing, bigfloats.  It has a
symbolic debugger source level debugger for maxima code.  Maxima is
based on the original Macsyma developed at MIT in the 1970's.  It is
quite reliable, and has good garbage collection, and no memory leaks.
It comes with hundreds of self tests.  William Schelter at University
of Texas, has been responsible for development since the mid 1980's.
See http://www.ma.utexas.edu/maxima.html for more information.  He has
recently been able to get DOE to allow him to distribute Maxima under
the GPL.
