!goto $help_conf

:pari

PARI/GP is an arbitrary precision number-theoretic calculator. Due to its

high speed, it is the ideal calculator for many computational needs of WIMS.

Many modules rely on it, including most exercises on linear algebra. If this

is unavailable, not much of your server will work correctly.

<p>

Recommended version: 2.1.*. (Other versions may present compatibility

problems.)

!goto end

:mupad

MuPAD is a very good symbolic algebra software. It is a bit slow to load and

is not open source, therefore it has only limited use by WIMS modules.

Modules making use of it include especially calculus-related online tools.

<p>

Due to its license policies, MuPAD must be obtained directly from its 

distributor (http://www.mupad.de/). Please follow instructions in the package

on how to install it, and put the exact installation path into the

configuration of MuPAD command.

<p>

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

problems.)

!goto end

:maxima

Maxima is an open source symbolic algebra package. It is used at most

occasions where derivatives and/or integrals need to be computed.

<p>

It is to be remarked that the most recent Maxima version (5.6 with GCL 2.4) 

has a bug preventing it from compiling under RedHat 7.*. If you run into

difficulties of this kind, get a copy of an earlier version (5.4) from 

<a target=wims_external

href="http://wims.unice.fr/download/other-packages/">http://wims.unice.fr/download/other-packages/</a>.

<p>

Recommended version: 5.4. (Other versions may present compatibility

problems.)

!goto end

:yacas

Yacas (Yet Another Computer Algebra System)

is a new open source symbolic algebra package. Due to its rapid development,

it is a very promising package. Therefore it may find more and more

uses in WIMS.

<p>

!goto end

:octave

Octave is an open source numerical analysis package. It is not yet used by

WIMS. So you can safely skip its installation for the time being.

!goto end

:m2

Macaulay 2 is a powerful software specialized in commutative algebra. For

the time being, it is only used in a few popup calculator tools. If

you don't install it, these few popup calculators will fail, but the rest of

the server will not be affected.

!goto end

:gap

GAP is a powerful calculator for group theory, actually used by two WIMS

tools computing finite groups. You will need GAP if you want these two tools

to work.

!goto end

:povray

Povray is a ray tracing graphing software. It is used in graphing tools to

render high-quality surfaces. It is now included in most recent Linux

distributions. If you have trouble with it, check first whether the package

is installed with your Linux system, and install it if necessary.

<p>

Recommended version: 3.0*-3.1*. (Other versions may present compatibility

problems.)
