12 ### placement does not have a place for the window. ###
13 fallback = windowplacement.random ###

15 ### attempt to place windows even when they ###
16 ### request a position (like XMMS). ###
17 ignore_requested_positions = 0 ###
18 # confirm_callback - set this to a function to have the function called ###
19 ### before attempting to place a window via history. If ###
20 ### the function returns 'true' then an attempt will be ###
21 ### made to place the window. If it returns 'false', the ###
22 ### fallback method will be directly applied instead. ###
23 confirm_callback = 0 ###
25 # filename - The name of the file where history data will be stored. The ###
26 ### number of the screen is appended onto this filename. ###
