wmArchUp is a very simple program used to monitor for package updates in Arch Linux. It uses the checkupdates script that come with pacman for safe checking if there is any package updates. It is a dockapp that is supported by X window managers such as Window Maker, AfterStep, BlackBox, Fluxbox and Enlightenment.
This dockapp is quite simple. It contains an Arch Linux logo icon. When there is not package updates then the Arch Linux logo icon is greyed. When there are package updates then the Arch Linux logo icon is blue. The program check for updates every 10 minutes.
A newer version may be available in the Window Maker dockapps git repository:
git clone https://repo.or.cz/dockapps.git
