Module: lib-tde.function.application_runner
This module helps with running applications as defined in autostart.
Running software that guaranteed running only once can be troublesome. For example you have written a shell script that launches a webserver. We would only want to start the webserver once.
-- this will run the script lib-tde.function.application_runner.run_once(os.getenv("HOME") .. "/launch-webserver.sh") -- returns true -- this won't run the script lib-tde.function.application_runner.run_once(os.getenv("HOME") .. "/launch-webserver.sh") -- returns false
