Getting favicon.ico into pelican

I had a need to publish specific files into the root of the generated output of my pelican site.
An easy way to do is using your pelicanconf.py file to designate a folder for these file and modify their path within pelican.
So in the content folder I created a folder 'extra' to accomodate these files.

STATIC_PATHS = ['documenten', 'images', 'extra',]
EXTRA_PATH_METADATA = {
        'extra/keybase.txt': {'path': 'keybase.txt'},
        'extra/robots.txt': {'path': 'robots.txt'},
        'extra/favicon.ico': {'path': 'favicon.ico'},
