Sphinx-build -E option

[Csaba O]

Hi!

I was wondering if somebody could confirm whether using the "sphinx-build -E" option (https://www.sphinx-doc.org/en/master/man/sphinx-build.html#cmdoption-sphinx-build-E) differs from issuing a "make clean" command in terms of deleting the build cache or not. Does the "-E" option mean the same "rm -rf $(BUILDDIR)/*" operation or does it "only" rebuild (rewrite) the environment without actually deleting it?

Thank you for your feedback.

Regards,

Csaba
