Notifies of available updates.

`pacman-update-count.sh` -- run as root to update available count.

`notify-updates` -- run to notify of available updates (gets value stored by `pacman-update-count.sh`).

```sh
# list options:

notify-updates --help
```

## Configuration

Example configuration file: `notify-updates.config`.

Configuration directory (hardcoded for now): `~/.config/notify-updates`.

## TODO

* `notify-updates` triggered to run after `pacman-update-count`
* `update.sh` script
