I would like to teach first-year students how to use
[https://www.usna.edu/CS/qepcadweb/B/QEPCAD.html QEPCAD] to solve systems
of rational inequalities ([https://groups.google.com/forum/#!msg/sage-
devel/QLEFLgkuXRg/bFAbvp6UWXwJ example]).
`sage-6.2.ova` displays the qepcad help with `qepcad?`, but it cannot be
used:
{{{
qepcad('(E x)[a x + b > 0]', vars='(a,b,x)')
Traceback (click to the left of this block for traceback)
...
RuntimeError: Unable to start QEPCAD
}}}
