:pari
6
PARI/GP is an arbitrary precision number-theoretic calculator. Due to its
7
high speed, it is the ideal calculator for many computational needs of WIMS.
8
Many modules rely on it, including most exercises on linear algebra. If this
9
is unavailable, not much of your server will work correctly.

:mupad
15
MuPAD is a very good symbolic algebra software. It is a bit slow to load and
16
is not open source, therefore it has only limited use by WIMS modules.
17
Modules making use of it include especially calculus-related online tools.
18
<p>
19
Due to its license policies, MuPAD must be obtained directly from its 
20
distributor (http://www.mupad.de/). Please follow instructions in the package
21
on how to install it, and put the exact installation path into the
22
configuration of MuPAD command.

Recommended version: 1.4.*. (Other versions may present compatibility
25
problems.)

:maxima
29
Maxima is an open source symbolic algebra package. It is used at most
30
occasions where derivatives and/or integrals need to be computed.
31
<p>
32
It is to be remarked that the most recent Maxima version (5.6 with GCL 2.4) 
33
has a bug preventing it from compiling under RedHat 7.*. If you run into
34
difficulties of this kind, get a copy of an earlier version (5.4) from

:yacas
43
Yacas (Yet Another Computer Algebra System)
44
is a new open source symbolic algebra package. Due to its rapid development,
45
it is a very promising package. Therefore it may find more and more
46
uses in WIMS.

:octave
51
Octave is an open source numerical analysis package. It is not yet used by
52
WIMS. So you can safely skip its installation for the time being.

:m2
56
Macaulay 2 is a powerful software specialized in commutative algebra. For
57
the time being, it is only used in a few popup calculator tools. If
58
you don't install it, these few popup calculators will fail, but the rest of
59
the server will not be affected.

:gap
63
GAP is a powerful calculator for group theory, actually used by two WIMS
64
tools computing finite groups. You will need GAP if you want these two tools
65
to work.

:povray
69
Povray is a ray tracing graphing software. It is used in graphing tools to
70
render high-quality surfaces. It is now included in most recent Linux
71
distributions. If you have trouble with it, check first whether the package
72
is installed with your Linux system, and install it if necessary.
73

74
Recommended version: 3.0*-3.1*. (Other versions may present compatibility
75
problems.)
