-- Save this file as "aweror.lua" in awesome's system library directory "/usr/local/share/awesome/lib",
-- "/usr/share/awesome/lib", or your own config directory "~/.config/awesome/".
-- You will also need a "ror.lua" file (contains your key bindings) in your config directory.
-- Now you need to generate and add the keybindings in your ~/.config/awesome/rc.lua
-- In the rc.lua file there will be a "root.keys(globalkeys)" command that sets
-- your keys, you need to add the following lines just before that command:
--
-- require("aweror")
-- globalkeys = awful.util.table.join(globalkeys, aweror.genkeys(modkey))


-- get our key bindings from separate ror.lua file
