-Maxima is a system for the manipulation of symbolic and numerical
-expressions, including differentiation, integration, Taylor series,
-Laplace transforms, ordinary differential equations, systems of linear
-equations, polynomials, and sets, lists, vectors, matrices, and tensors.
-Maxima yields high precision numeric results by using exact fractions,
-arbitrary precision integers, and arbitrarily precision floating point
-numbers. Maxima can plot functions and data in two and three dimensions.
+
+Maxima is a GPL computer algebra system based on DOE-MACSYMA. It
+is comparable to commercial systems like Mathematica and Maple. It
+emphasizes symbolic mathematical computation: algebra, trigonometry,
+calculus, and much more.
+
+For example, Maxima solves x^2-r*x-s^2-r*s=0 giving the symbolic
+results [x=r+s, x=-s].
+
+Maxima can calculate with exact integers and fractions, native
+floating-point and high-precision big floats.
+
+Maxima has user-friendly front-ends, an on-line manual, plotting
+commands, and numerical libraries. Users can write programs in its
+native programming language, and many have contributed useful packages
+in a variety of areas over the decades.
+
+Maxima is GPL-licensed and largely written in Common Lisp. Executables
+can be downloaded for Windows, Mac, Linux, and Android; source code
+is also available. An active community maintains and extends the
+system. Maxima is widely used.
+
+SBo Installation notes:
+- The info files are not compressed.
+- Two .lisp files install to /usr/info.
+These are required for maxima's help facility.
