Merge branch 'install' into docs-next
Mauro says: Sphinx installation is not trivial, as not all versions are supported, and it requires a lot of stuff for math, images and PDF/LaTeX output to work. So, add a script that checks if everything is fine, providing distro-specific hints about what's needed for it to work.

There's a script that automatically check for Sphinx dependencies. If it can

command line options for your distro::
