Current Version	Released	Terms
1b9	2008-02-03	GPL 3.0

JACAL is an interactive symbolic mathematics program. JACAL can manipulate and simplify equations, scalars, vectors, and matrices of single and multiple valued algebraic expressions containing numbers, variables, radicals, and algebraic differential, and holonomic functions.

JACAL is a GNU package.

New:

Larceny (Scheme) is now supported.
Installation improved.
Error reporting improved.
