As the relationships work on a simple parent child structure more and more pages can be nested as required.
This example also shows that if needed you can automatically have multiple page names point towards the same page. This can be important if you have an old page name that needed to be changed, but has been referenced in the past.
Alternative page names can be set in the pages.json file, using the variable "aliases", and multiple alternative names can be entered as a comma separated list.
