Enable debug output.

Wait for command to finish executing before continuing, helpful for ensuring
that a *before-sleep* command has finished before the system goes to sleep.
# DESCRIPTION
swayidle listens for idle activity on your Wayland compositor and executes tasks
@ -36,6 +40,10 @@ Sending SIGUSR1 to swayidle will immediately enter idle state.
If built with systemd support, executes _command_ before systemd puts the
computer to sleep.
Note: this only delays sleeping up to the limit set in *logind.conf(5)* by
the option InhibitDelayMaxSec. A command that hasn't finished by then will
continue running after resuming from sleep.
All commands are executed in a shell.
