Note: The script will check for the required commands itself, so you do not have to.

hfl-set-mint-theme-to-match-time-of-day

or:

hfl-set-mint-theme-to-match-time-of-day --continuous [ <at_queue>=s ]

or:

hfl-set-mint-theme-to-match-time-of-day (--help | -H | -h | -?)

or:

hfl-set-mint-theme-to-match-time-of-day (--version | -V | -v)

--version, -V, -v
- Print version and copyright information.
--help, -H, -h, -?
- Print the usage message.
--continuous
- Sets up a recursive at job that runs the command when the time of day changes. <at_queue> specifies which at queue to use; if not given, defaults to 's'. This queue needs to be used exclusively for this script.

To make this program run continuously from startup, add it to the "Startup Applications" with the --continuous flag and a delay shorter than the delay of any application with visual elements, such as windows or tray icons.
Theme does not update to some applications and system utilities without restarting the program or logging out and logging back in.
When run in continuous mode, this script logs output and errors to:
```
~/hfl-set-mint-theme-to-match-time-of-day.log
```
This script use at instead of cron because gsettings does not work with cron.

Automated tests are done using shUnit2 and ShellCheck.
