wmpamgen
Preferred applications menu generator for Fluxbox,OpenBox,Window Maker
...The generated menu only includes entries for the preferred applications which are already installed when wmpamgen is run. Therefore, to ensure the menu is up-to-date, wmpamgen needs to be run on a regular basis: at startup of the window manager, or when a preferred applications is installed/removed for instance. Under Linux, this can be automated using the inotify API.
