jsmath_path = '/javascript_local/jsMath/easy/load.js'
should be
jsmath_path = '/javascript_local/jsmath/easy/load.js'
After rebuilding (with the "--jsmath" option), jsMath should work in the
fast static documentation. For example, visit
http://localhost:8000/doc/static/tutorial/tour_algebra.html .
The live help is already typeset, because a worksheet also loads jsMath,
albeit in a slightly different way:
http://trac.sagemath.org/sage_trac/ticket/4714 .
I suggest adding the following to
SAGE_ROOT/devel/sage/doc/common/templates/layout.html so direct access,
via file://, access also works:
{% block extrahead %}
<script type="text/javascript"
src="../../../../../../../local/notebook/javascript/jsmath/easy/load.js"></script>
{% endblock %}
Also, "sage --advanced" doesn't list the docbuild options, including
"--jsmath".
Sorry, if I'm wrong or these are already known.
