- Updated the `parse_args()` function to include a new argument `--logfile`, which allows users to specify a custom log file. The default value is "none".
- Modified the `main()` function to check if the user provided a log file using the `--logfile` argument. If a log file is specified, it adds a FileHandler to the logger and sets the logging level based on the `--loglevel` argument.
- Updated the `remindme_caldav.service` file to include the `--logfile` argument in the `ExecStart` command. This ensures that the log file is used when the service starts.
* Move from basic logging to more detailed logging with a log file.
* Improve error handling in several functions.
* Modify the way log messages are displayed.
- The Makefile now includes installation instructions for Debian/Ubuntu based systems.
- The README has been updated with more detailed descriptions of the script's purpose, how it works, and how to use it.
- The service file has been added to manage the remindme_caldav daemon on a systemd-based system.
