libghc-xmonad-dev - 0.14.2-3+b1 main

Xmonad is a minimalist tiling window manager for X, written in
Haskell. Windows are managed using automatic layout algorithms,
which can be dynamically reconfigured. At any time windows are
arranged so as to maximise the use of screen real estate. All
features of the window manager are accessible purely from the
keyboard: a mouse is entirely optional. Xmonad is configured in
Haskell, and custom layout algorithms may be implemented by the user
in config files. A principle of Xmonad is predictability: the user
should know in advance precisely the window arrangement that will
result from any action.

This package is what you need to build your custom configured xmonad
binary.

This package provides a library for the Haskell programming language.
