Title: Yacas Documentation
Author:	Ayal Pinkus (apinkus@xs4all.nl)
Abstract: Yacas (Yet Another Computer Algebra System) is a small and
 highly flexible computer algebra language. The syntax is very close
 to Mathematica. The distribution contains a small library of
 mathematical functions, but its real strength is in the language in
 which you can easily write your own symbolic manipulation
 algorithms. It supports arbitrary precision arithmetic.
