Example usage:
Page reference without image: {{page|1}}
Page reference with non-PDF file: {{page|1|file=filename.jpg}}
Page reference with PDF file: {{page|1|file=filename.pdf|page=1}}
This template also uses two references {{#set_associated_image:}} and {{#set_associated_index:}}. The purpose of those two tags are to associate a specific page in a pdf document with the corresponding page which contains its plain text in the main namespace. In other words, link from File:Something.pdf to </nowiki>Some page</nowiki>. These settings are associated with the "Return to text view" which is displayed at the top of a PDF file (eg here). Note that if you are stepping through a PDF file the "Return to text" link will not update, but if you refresh the page it will become correct. More information can be found on our github page here.
