2008-09-14Import fricas-1.0.3 as math/fricas.ahoka6-0/+3189
Packaged by Aleksej Saushev with help from Yorick Hardy in the pkgsrc-wip project. FriCAS is a fork of Axiom. FriCAS algebra library is written in a high level strongly typed language (Spad), which allows natural expression of mathematical algorithms. FriCAS uses lightweight developement methodology. Compared to Axiom FriCAS is significantly restructured -- it is more portable and fixed several defects. FriCAS removed rather large unused parts (without removing functionality). It is expected that FriCAS will be much easier to maintain than original Axiom.
