-- With these functions you can bind a key to start an application if
-- it's not already running, or go to it if it is. You can use it by
-- doing something like this in your bindings file:
--
-- kpress(MOD1.."C", "app.byname('xterm -title shell', 'shell')"),
-- kpress(MOD1.."T", "app.byclass('emacs', 'Emacs')"),
--
-- The byname function expects an executable and a window title, the
-- byclass expects a class.
--
-- For emacs users there's also app.emacs_eval, and app.query_editfile,
-- which interacts with any currently running emacs process (using
-- gnuclient), or starts emacs to run the given command.
-- app.query_editfile is a replacement for query_lib.query_editfile to
-- use the currently running emacs rather than ion-edit.
