parenthesis.

Probably what I say here applies to both Axiom and FriCAS.<br>
<br>
If you start FriCAS via the &#39;fricas&#39; script, then (depending on how=
 you<br>
have compiled FriCAS and what resources are available) it will spawn a<br>
few processes, among them is HyperDoc, a viewport manager, and the<br>
actual FriCAS process (still called AXIOMsys). All this is managed by a<br>
super process (called s(uper)man). In your case, the AXIOMsys process<br>
computes the graphics and wants to transmit it to the viewport manager<br>
(an engine that displays the data and lets you interactively work with it).=

been turned off for some reason by the ./configure run. Without looking<br>
