I'm afraid I haven't wrote sug an article. Nicolai may be confusing it with the on I wrote about security.
However, it's pretty simple. You create a new file in your module folder,usually naming it [ModuleSystemName]_cpl.aspx. The input fields whose values you want to save, you give them the name of the XPath you want them to represent in GlobalSettings.aspx. If you wanted to create a field that changes the SQL server, you'd set it's name attribute to "/System/Database/SQLServer".
You don't have to worry about saving the values. Simply setting the action attribute of your form to ControlPanel_Save.aspx will save the data in GlobalSettings.aspx.
