-    The  following  function allows  the  user  to  get  the list  of  available
-    wallpapers I have  in my wallpapers directory. This depends  on the variable
-    described  in  [[#Variable_definitions-Wallpapers_directory-23b54f4f]].  By  the
-    way, the assert on line 3 allows Lua to wait for ~popen~ to run.

-    This function is another  one that sets a random wallpaper  from the list of
-    wallpapers  provided  by  ~get_papes()~  described above.  This  depends  on
-    [[https://github.com/l3ib/nitrogen/][Nitrogen]] and [[https://github.com/dylanaraps/pywal][Pywal]].
+    This    function   sets    a   random    wallpaper   from    the   directory
+    =~/Pictures/Wallpapers=, see [[file:bin.org::#pape-update-bdecbadf][pape-update]] in  my custom scripts. This depends
+    on [[https://github.com/l3ib/nitrogen/][Nitrogen]] and [[https://github.com/dylanaraps/pywal][Pywal]].
