settings (hackage): This library aims to be a tool for constructing a settings management UI on top of the relevant part of your program state. The settings tree structure definition is separate from the actual setting values, so your program logic code doesn't need to be changed. It can access the settings as regular Haskell values.  The settings are presented to the user as a tree hierarchy. The idea has some similarity to git config and Weechat's settings system, but isn't identical.  To get started, see the tutorial in the Data.Settings module.
