[SciPy-Dev] Can a PR be configured to run only the build of the docs?

[Warren Weckesser]

I am working on an addition to the docs that only touches one existing
.rst file and adds one new .rst file.    For the initial pull request,
I want to run just CircleCI and generate the CircleCI docs artifact. I
haven't followed all the changes to how CI is currently configured and
run.  Is there text that I can add to the commit message (or some
other method) so that only the CircleCI jobs are run?
