{- $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.Prompt.AppLauncher as AL
Then you can add the bindings to the applications.
