 -- Functions for setting the wallpaper.
 --
--- There are two levels of functionality provided by this module:
---
--- The low-level functionality consists of two functions.
--- @{set} an already-prepared wallpaper on all screens and @{prepare_context}
--- prepares things to draw a new wallpaper.
---
--- The low-level API can for example be used to set solid red as a wallpaper
--- (see @{gears.color} for details on the supported syntax):
---
---     gears.wallpaper.set("#ff0000")
---
--- Ontop of these low-level functions, the remaining functions implement more
--- useful functionality. For example, given a screen object `s`, an image can be
--- set as the wallpaper as follows:
---
---     gears.wallpaper.maximized("path/to/image.png", s)
+-- This module is deprecated, please use `awful.wallpaper`.
