Comment(by rbeezer):
Hi Jason,
The purpose of the line in question is not really a doctest of the
existence of the packages.
The function {{{check_tkz_graph()}}} will emit a warning *once* per
session, if needed, and then be silent. In order to doctest the latex
output, I need to be sure that the warning doesn't get mixed in. So I
call this function in the doctest, which *may* produce a warning. Then
the latex output will be "pure."
So I need to be certain this line runs, and I don't want to test its
(variable) output. If it is tagged "optional" will it always be run in
testing, no matter what?
In any event, if there is a change here, I'll make it as part of some
other revision, so I don't want this to hold up getting this merged.
Rob

one argument against this is that it is not testing the installation of an
optional spkg.

maybe (in a different ticket) we could have a small spkg that installs the
needed .sty files for this into the sage local tex tree.
