VAR files use the extension #.var. That is for Jack.html a VAR file would be named Jack#.var. The VAR file is a text format containing single line name=value pairs. For example:
Name=Jack Smith
;Acting CEO, but for public we use just CEO
Title=CEO
Any line starting with a ; is ignored and treated as a comment. In the future VAR files will optionally be able to use XML as well.
