When you install cups on a system configured to not install documentation (for example, the fedora 29 docker image), when you access the web interface on http://localhost:631 you get "Not Found" instead. 
Looking at the spec file, the problem seems to be that the /usr/share/cups/www/index.html file is installed as documentation, but without the index file if you want to manage your printers you have to go directly to http://localhost:631/printers or http://localhost:631/admin :

Reproducible: Always

Steps to Reproduce:
1. Install cups with "dnf install --nodocs cups" or with the the line "tsflags=nodocs" in /etc/dnf/dnf.conf
2. Access http://localhost:631

Actual Results:  
You get the message "Not Found"

Expected Results:  
You should see the "home" tab of the web interface

Only the files under the help directory should be marked as documentation, I think. As it is, it's crippling the web interface. Anybody that doesn't know this will think that the web interface has stopped working.
