-# The jit/docs Makefile uses the executable $(SPHINXBUILD),

-# sphinx is packaged in Fedora and EPEL 6 within "python-sphinx",
-# in RHEL 8 within "python3-sphinx",
-# and in openSUSE within "python-Sphinx".
-#
-# For EPEL6, python-sphinx is sphinx 0.6.6, which is missing various
-# directives (e.g. ":c:macro:"), so we need the variant
-# python-sphinx10 package.  The latter installs its executable as
-#   /usr/bin/sphinx-1.0-build
-# so we needed to override SPHINXBUILD with this when invoking "make".
+# Use the Sphinx installed in a virtual environment so that
+# we don't depend on a system package.
