+-- WorkspaceDir is an extension to set the current directory in a workspace.
+--
+-- Actually, it sets the current directory in a layout, since there's no way I
+-- know of to attach a behavior to a workspace.  This means that any terminals
+-- (or other programs) pulled up in that workspace (with that layout) will
+-- execute in that working directory.  Sort of handy, I think.
+-- 
+-- Requires the 'directory' package
+--

+--
+-- > import XMonad.Layout.WorkspaceDir
+-- >
+-- > layouts = map (workspaceDir "~") [ tiled, ... ]
+--

+-- >  , ((modMask .|. shiftMask, xK_x     ), changeDir defaultXPConfig)
+
+-- %import XMonad.Layout.WorkspaceDir
+-- %keybind , ((modMask .|. shiftMask, xK_x     ), changeDir defaultXPConfig)
+-- %layout -- prepend 'map (workspaceDir "~")' to layouts definition above,
+-- %layout -- just before the list, like the following (don't uncomment next line):
+-- %layout -- layouts = map (workspaceDir "~") [ tiled, ... ]
