Desktop (WinForms) applications based on .NET and Visual Studio use a file named App.config to store configuration settings for most things that are configurable.
The PPJ Framework also uses the App.config file to read its settings.
All the settings supported by the PPJ Framework can be edited easily using the Configuration Tool provided in the PPJ Utility package.
The skinning engine can be configured by code or entirely from outside the application using the App.config file. For the definition of all the supported settings read the Skinning Support Configuration section.
