This is copy of the annoucement that I posted in newsgroups: FriCAS is an advanced computer algebra system. Its capabilities range from calculus (integration and differentiation) to abstract algebra. It can plot functions and has integrated help system.
FriCAS 1.1.0 builds on Linux, many Unix like systems (for example Mac OSX and Solaris 10) and Windows. FriCAS is build on top of Common Lisp; several Lisps can compile and run FriCAS -- currently supported are GCL, SBCL, Clisp, ECL, Closure CL (former OpenMCL) and CMU CL.
