+{- $usage
+   This module is intended to allow the launch of the same application
+   but changing the parameters using the user response. For example, when
+   you want to open a image in gimp program, you can open gimp and then use
+   the File Menu to open the image or you can use this module to select
+   the image in the command line.
+   
+   We use Prompt to get the user command line. This also allow to autoexpand
+   the names of the files when we are writing the command line.
+ -}
+
+{- $tip
+
+First, you need to import necessary modules. Prompt is used to get the promp
+configuration and the AppLauncher module itself.
+
+> import XMonad.Prompt
+> import XMonad.Actions.AppLauncher as AL
+
+Then you can add the bindings to the applications.
